What is a construction waste crusher? It is simply a machine used to pulverize construction waste. The so-called construction waste is what we commonly refer to as abandoned building concrete, as well as masonry, etc. Usually, people think that the use of construction waste itself is of little value, but after it is crushed by pulverizers like abandoned building concrete and masonry, it can be renewed. The production of building materials such as concrete, floor tiles, and wallboard can be applied to the base of highway pavements. At the same time, it also saved a large amount of landfills, avoided the destruction of the soil, and effectively protected the environment. With these two points, the construction waste shredder has become an environmental guard for the machinery industry. First, each time before starting construction of the garbage crusher, it is necessary to carry out the idle load operation, and to check whether there is any leakage phenomenon or other abnormal phenomena on the next line to prevent damage to the wearing parts. Second, the operator should regularly inject new oil into the vulnerable parts of construction waste to maintain the lubricity of wearing parts, and it is also necessary to replace the butter when it is critical. Third, the crusher is the most easily damaged part of the construction waste crusher. In the crushing process, if the material is mixed with other iron and impurities, it will accelerate the damage of the blade, so install a filter at the feed port. Net, sieve the material out. Fourth, if you want to extend the use of construction waste crusher wearing time, an effective way is to ensure the stability of the voltage at work, can not be ups and downs, but also to avoid long-term overload operation of the equipment. The maintenance method of the construction waste crusher wearing parts is introduced here for everyone. Knowing these methods can greatly reduce the damage rate of the accessories and reduce the cost for the users. At the same time, it also achieves the output. A certain standard.

In the process of urbanization, rubbish as a product of urban metabolism was once the burden of urban development, especially construction waste accounted for the majority of urban waste. Looking at the course of development of various countries in the world, many cities have embarrassed the situation of rubbish besieging the city. Human society will inevitably be bound by oneself at the same time. Nowadays, with the transformation of ideas and technological advances, the construction waste industry is considered to be an inexhaustible “urban mineral deposit” with development potential and a “misplaced resource”. Research shows that more than 90% of the construction waste can be used as raw materials for construction materials and reused in urbanization. This is not only the deepening and deepening of people’s understanding of construction waste, but also an inevitable requirement for urban development. The construction waste crusher industry in China started relatively late, but through the rapid development in recent years and the increasing popularity of the country in environmental protection, China’s construction waste treatment industry has begun to take shape, and the capacity of the waste treatment market has increased significantly. The penetration rate has rapidly increased and the number of companies entering the sanitation industry has also increased rapidly. Now China's construction waste crusher market has entered the growth period from the lead-in period and is rapidly moving towards maturity. With the environmental protection concept deeply rooted in people's minds, environmental issues have gradually attracted the attention of governments and people of all countries. Energy conservation and environmental protection have gradually become one of the world's development themes. They have begun to provide a broad development opportunity for the construction waste management industry. In the world, billions of tons of garbage are produced each year, and the average annual growth rate of garbage is 8.42%. While the growth rate of garbage in China is more than 10%, it is one of the fastest growing countries in the world. It only generates nearly one billion tons of cities each year. construction rubbish. The cumulative stockpiling of municipal solid waste in China has reached 7 billion tons, of which construction waste accounts for the bulk of this. Under such a huge weight of urban waste, there is reason to believe that the waste processing industry will become the star industry in the future.

Grinding is one of the most important steps that need high cost in the ore beneficiation plant. The grinding fineness of the construction waste crusher has great influence on the gradation level of the minerals and the recovery rate of the materials. As the domestic mining industry is developing rapidly, the construction waste crusher manufacturers have made strict requirement for the grinding fineness of construction waste crushers. Therefore, how to effectively control the grinding fineness has been the concern for most mining machinery enterprises and customers. Here our experts will give users some advice about how to make the most use of the construction waste crushers for realizing the perfect grinding effect: 1. The abrasion degree of the construction waste crushers blades is a core problem we need to care about. When the blades are worn, few materials will be fed back which will cause the grinding fineness to become larger. 2. Strong abrasion will influence the smooth work of the construction waste crusher by reducing the service life. Therefore, users should try their best to reduce the abrasion between construction waste crushers accessories. 3. We should also pay attention to the rotary speed of the construction waste crusher. To rotate too quickly or too slowly will cause serious problems to the equipment. Therefore, before and during the operation of the construction waste crusher and classifier, we should adjust the rotary speed to the proper one in order to guarantee the excellent performance of the mining machines. 4. The size and height of the construction waste crushers opening mouth plays an important role in the ore beneficiation process. The bigger the opening mouth is, the larger the material feeding amount gets and the finer the grinding materials will become; vice versa.

At present, when China treats construction waste, the way that is consistent with sustainable development is to recycle the reused construction waste, and to use it in the pavement base course, building materials field, etc., and to produce concrete bricks and concrete blocks. The acceleration of the urbanization process requires us to invest more in construction waste crusher and apply them effectively. The mobile crushing plant produced by SBM Heavy Industries is a crushing equipment for the treatment of construction waste. It has the following advantages: Easy to move The customer can open the construction waste mobile crushing station to the construction site according to their own actual needs. After completion, the customer can directly go to the next site and do not need to build additional auxiliary facilities to solve the transportation problem. Multi-level combination The mobile crushing station can select jaw crusher, impact crusher, cone crusher and the like according to the crushing material, and the selectivity is more flexible, and the work can be performed at any time and place. Simple process Ordinary crusher reaches the construction waste crusher cavity of the crusher. The feeder and the crusher are transported by a belt conveyor placed on the surface of the crusher, and the crusher and feeding device of the crushing station to which the mobile crushing station belongs. The machine is closely adjacent to each other and does not require the transmission of the conveyor. The raw material of the mine surface is directly transferred to the feed inlet of the crusher by electroplating, and the raw material is injected into the crusher at a fixed speed, which not only reduces the The necessary processes also speed up production and save costs. What the SBM mobile crushing station “eats” into is construction waste such as bricks and concrete blocks. What spits out is a recycled building aggregate that can replace natural sand and gravel. It is a construction waste crusher that is in line with the current sustainable development strategy. . SBM mobile crushing station can not only be used for the crushing of construction waste, but also can be used on site for construction site access and foundation backfill on the spot. It can also be used to raise reinforced concrete in the site. It is a multi-purpose machine and is your ideal crushing equipment.

At present, the use of construction waste as a gravel aggregate after treatment and recovery can meet the national standard sand standards, and it also faces the problem of recognition. In order to verify this problem, the research project of the Handan City Science and Technology Bureau undertaken by the Hebei University of Engineering has recently passed the provincial level research project “A Study on the Influence of Recycling Construction Aggregate Recycled Aggregate on the Performance of Reclaimed Concrete Aggregates for the Three-year Change of Handan City”. Expert acceptance and identification. After 1 ton of construction waste crusher, 70% are coarse aggregates such as gravel and fine stone, and the remaining 30% are fine aggregates such as sand. These recycled aggregates can completely replace natural sand and sand, even better than natural sand. stone. According to reports, after more than two years of experimental research, the research team conducted comparative tests on the compressive strength, tensile strength, flexural strength, elastic modulus, and bond properties of recycled aggregates of construction waste, and pointed out the use of construction. Garbage Recyclable aggregates can be made from medium-strength concrete instead of natural aggregates. Experts agreed that this research topic is in line with the national industrial policy and provides a strong theoretical basis and data support for the use of a large amount of construction waste generated from the demolition of old cities. Comprehensive utilization of a large amount of construction waste reduces the pollution to the environment and reduces natural resources. The mining and consequent energy consumption and transportation will help relieve traffic pressure, reduce environmental treatment fees and landfills. Its social benefits, economic benefits, and environmental benefits are significant, and it has broad prospects for popularization and application. At present, as China attaches more and more importance to the development of the value of construction waste, it will also promote the gradual maturity of China's construction waste crusher technology.

What can construction waste do? In the past, people dealt with construction waste simply by stacking and burying it. Its understanding only differs from that of domestic waste. It is bulky and difficult to transport and has no concept of recycling of construction waste. However, with the soaring construction waste volume and the introduction of circular economy, people have to re-emphasize and define construction waste, and vigorously promote the recycling of construction waste. Since the 21st century, China's Construction waste crushing production line road has gone through nearly 20 years of ups and downs. In the past two years, the recycling of construction waste has achieved a real breakthrough. The reason is better than the improvement of current policies, the research and development of construction waste disposal equipment, and the transformation of people's ideas. In times of favorable conditions, the construction waste is becoming a major trend. Why is it important to mention construction waste disposal equipment? In the initial stage, China had cited foreign technology equipment. Naturally, the high cost of the previous period would not have been said. Problems occurred in the production process, and there was no way to deal with it in time after the sale. At the same time, the standards for recycled building materials and domestic Some access to the construction waste industrial chain into a deadlock. For this reason, only by mastering the core technological means can a comprehensive construction waste recycling become a reality. As the earliest company to carry out construction waste crusher in China, we took the lead in developing a mobile construction waste crushing station to help cities solve the construction waste crisis. The mobile equipment is very suitable for urban operations due to its advantages of flexibility, convenience, high efficiency, and environmental protection, realizing the source treatment of construction waste, and processing construction waste into various recycled aggregates on site.

In construction waste crusher, the first step is usually ore crushing, hence, selecting a suitable type and specification of crusher machine is very important for improving production efficiency of construction waste crusher. Factors influencing selection of crushing equipment are mainly physical properties of the ores like hardness, density, viscosity, clay content, and moisture and so on, handling capacity, product granularity, equipment configuration, etc. The crushing equipment can be divided into coarse, medium and fine types. The largest ore block of coarse crushing equipment is generally not more than the 0.8 to 0.85 times of the width of crusher feeding port. While that of medium and fine crushers is generally not more than 0.85 to 0.9 times. 1. Selection of coarse crushing equipment The coarse crushing equipment of metal mine concentrator is usually jaw crusher which is most widely used or gyratory crusher. In some non-metallic or cement industries, when processing medium harness or soft ores, we also can use impact crusher. In designing large and medium construction waste crusher, when selecting coarse crushing equipment, we should carry out technical and economic comparison such as installed power, equipment weight, infrastructure investment, production and operation fees, device configuration, advantages and disadvantages of technological operation so as to determine to use jaw crusher or gyratory crusher. While designing medium and small construction waste crusher, in order to adapt to large size of ore block of quarry plant, we should use the coarse crusher which is suitable for sizes of ore blocks. Advantages of jaw crusher are simple structure, light weight, low price, easy maintenance and transportation, reliable work, convenient adjustment of row ore mouth and so on. When crushing wet ore or ore containing more clay, it's not easy to jam. Disadvantages of jaw crusher are easy abrasion of lining board, low handling capacity compared with gyratory crusher, uneven product granularity, etc. Generally speaking, the jaw crusher has wider application, which can be used in large, medium and small construction waste crusher. Merits of gyratory crusher are low power consumption, continuous crushing, high handling capacity, even distribution of abrasion of lining plate in crushing cavity, even product granularity. Demerits of gyratory crusher are heavy body weight which requires s a solid foundation and high machine body which increase height of plant. What we should pay attention to is that taking ore receiving of both sits when using gyratory crusher in large construction waste crusher so as to improve handling capacity of crusher and make abrasion of lining board even. 2. Selection of medium and fine crushing equipment We generally use cone crusher including single-cylinder hydraulic cone crusher as the medium and fine crushing equipment when crushing hard or medium ores. While select short-head cone crusher as the fine crushing equipment. When crushing especially hard ores, we can use super-heavy cone crusher. While crushing brittle materials, we use roller crusher, impact crusher and hammer crusher. Advantages of cone crusher are large crushing force, light weight, small external dimension, low price, large production capacity, big reduction ratio and so on. Disadvantages of cone crusher are the manufacturing of hydraulic system and bearing structure of dynamic cone is relatively complex. Merits of roller crusher are simple structure and easy manufacturing. Disadvantages are easy abrasion of roller and low handling capacity.

The construction waste treatment production line is a device specially designed for processing and processing construction waste. It can be divided into fixed construction waste crusher and mobile type, while the mobile type is the current industry using more advanced technology, process technology is superb. The fixed construction waste production line includes feeders, belt conveyors, H-breakers, counter-attack breakers, vibrating screens and other equipment. It has relatively high site requirements and a large area of ​​occupied land. Therefore, in order to make up for the shortcomings of large occupied area, , Our company has developed and produced a more flexible and convenient mobile crushing station equipment. This medium-to-large equipment is a simplified part of the fixed equipment, installed in a set of drive racks, thus forming a mobile construction waste processing line. After effective disposal of construction waste, there are many new uses, such as processing recycled bricks. There are too many building rubbish in the brick-concrete structure, more than mixed concrete waste, but the ordinary concrete crusher equipment can not effectively break the clay brick, such as smashing, counterattack, cone crushing, because the clay brick absorbs water and has high humidity. And clay bricks have low strength and are not suitable for making coarse aggregates. They can only be made into fractals and used as cementitious materials. So we combine the grinding and recycling mode of fly ash, plus the roller crushing process to form the combined grinding and co-pressing operation mode. This process technology can solve hundreds of millions of tons of brick-concrete construction waste in China, and have the capacity of concrete construction waste crusher, which can be described as “a knowledge of art”. Through the reuse of construction waste, the amount of construction waste can be effectively reduced and the amount of construction waste can be reduced. At the same time, the use of new materials through waste recycling and reuse is also a double-edged phenomenon. Currently, there are not many investors in the construction waste disposal industry. If you want to get involved, you can contact us. Our professionals will give a warm reply.

Today's construction waste can no longer be called garbage. With construction waste crusher, they are "treasures." Construction waste is now a resource that plays an important role. Previous construction waste can be accused of polluting the environment and occupying the area of ​​use. But now, with the development of the domestic economy, we can make the most reasonable use of construction waste - construction waste processing equipment. The use of construction waste disposal equipment not only reduces our reliance on non-renewable resources, but also reduces the pollution caused by construction waste. Most of construction waste is solid waste, which is generated during the maintenance and demolition of old buildings. The pollution-free inorganic substances in construction waste account for more than 90%. Inorganic materials have the characteristics of acid resistance, alkali resistance, water resistance, chemical stability, and stable physical properties. These properties of construction waste determine that it is treated as a good recycled building material, and wastes with pollutants can be reused as renewable resources. Of course, although we now have a good way to deal with these construction wastes, we need to reduce the sources of construction waste. Strongly support the establishment of construction waste crusher. Improve the utilization rate of construction waste, and adopt various preferential policies to vigorously develop and promote recycled materials products. However, in our country, most engineering contractors do not want to increase their input in waste management, except for the immediate value of construction waste that is recovered, because the cost of waste management under investigation is significantly higher than the cost of waste disposal as waste. Therefore, we should also increase the disposal costs of construction waste, and encourage more processing companies to provide more preferential policies.

In the crushing operation of construction waste crusher, the crushing process is the first step in the construction waste disposal operation. The normal stability of this process directly affects the follow-up work of construction waste. The construction waste treatment equipment and test sieve are the second part of the closed circuit, which can guarantee the product's particle size requirements without affecting the grinding operation. The construction waste crushing process generally includes the construction waste screening operation, and the total of the broken parts constitutes a broken replacement surface flow. Generally used in the smashing process is two-stage or three-stage crushing. The two stages of the crushing process are divided into two sections, open and closed. The crushing granularity of construction waste treatment equipment products must meet the requirements of users, and at the same time as meeting the requirements, it can ensure that the normal operation of the machine is not affected. In the construction waste treatment production process, the crushing stage is the first stage, according to different types of waste treatment, and different crushed particle sizes. In the process of crushing construction waste disposal equipment, in general, the crushing of building waste crusher is broken by primary. In the two stages of crushing process, most of the waste disposal processes are closed-circuit processes. Segments are produced from construction waste crusher and screen cables. The construction waste crusher is mainly classified and broken in two parts. During the crushing process, the ore is bulky and it is impossible to crush it to the desired fineness, and it must be segmented. The secondary process is only applicable to the mining of small ore, the total reduction ratio is not large, the number of broken ore is not large, generally less than 1 kiloton per day. In the process of processing, because the last stage of garbage disposal is open, the requirements for the granularity of broken products are often used in large-scale garbage disposal, in which objects with relatively high moisture content are treated, and when the materials are processed, the construction waste treatment equipment is still used. Plays an important role.
