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. SBM Machinery Co., Ltd. is a company dedicated to large and medium-sized series crusher, sand making machine, mobile crushing station, mobile screening station, feed screening equipment, urban construction waste crushing equipment and wear-resistant materials, integrating research and development, production Sales and sales of high-tech enterprises. Among them, the mobile crushing station of construction waste treatment equipment is one of the company's main research directions. The technology in the field of construction waste disposal has taken the lead in China and no one can compare with it. The problem of construction waste has become a problem that people in the country have attached importance to. With the development of science and technology, SBM Machinery Co., Ltd. will change the fate of construction waste, turn construction waste into treasure to benefit people, realize clean production and self-closing. Circular economy industrial chain, protect the urban ecological environment, and help the city to embark on a virtuous cycle of sustainable development in the reconstruction or expansion.
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. If you want to engage in the construction waste treatment industry, please contact us and we will serve you wholeheartedly.
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.
Construction waste is produced along with the development of the city, especially in large and medium-sized cities in China. Due to the dense population of cities, more and more city buildings are being replaced, and a large amount of construction waste has become an intractable problem. The matter, and the government attaches great importance to the disposal of construction waste, and encourage the development of construction waste-related industries. However, for everyone or manufacturers, more consideration is given to the benefits of construction waste crusher. If the benefits are realized, it is better to bring greater social and environmental benefits. Construction waste crusher manufacturers solve this problem. The construction waste crusher currently has quite mature technology, and its function is gradually improved. In the past, construction waste needs to be pulled down to treat the construction waste around the city. However, there is already a construction waste crushing station that can be exploded in situ. The benefits can bring about the greatest reduction in transportation costs, thereby reducing the difficulty of recycling construction waste. The current construction waste crusher has the same crushing capacity as gravel production and ore crushing. It is easy for the crushing of construction waste. What needs to be improved is how four-line maneuvering is flexible and clean and environmentally friendly because construction waste is carried out in cities. Processing, if the equipment is not flexible enough will increase the equipment transport, installation time and cost issues, if the equipment is not environmentally friendly, secondary pollution such as noise and dust will directly affect people's normal work and life. Our company's own equipment has a strong capacity for construction waste crusher, and it has a flexible body, clean and environmentally friendly protection measures, so that the construction waste crusher can play a huge role in the city's construction waste disposal without any equipment of the past. , And has produced huge social and economic benefits, not only solved the city construction waste, and beautified our urban environmental problems.

Jaw crusher is a kind of equipment to deal with construction waste. Jaw crusher is an indispensable equipment in construction. construction waste crusher are required for concrete and large stones, and then conveyed by a belt conveyor to a cone crusher to be broken again. The working part of the jaw crusher is divided into two jaws, one is the fixed jaw (fixed jaw), its position is vertical (or the upper end is slightly cambered) and is fixed on the front wall of the body, and the other is the movable jaw. (Moving), its position is inclined, and the fixed jaw plate forms a large and small crushing chamber (working chamber). The activity sacral plate performs periodic repetitive motions against the fixed sacral plate. Open it, and close it. When opened, the material enters the mouth and the finished product comes out from below; when closed, the material placed between the two jaws is broken by crushing, bending, and chapping. In recent years, construction waste has increased at an annual rate of 80%. In addition, the garbage has been dumped indiscriminately and has caused serious environmental pollution in the city. Of course, some construction scrap metal such as steel bars and iron wires can be collected and classified and then processed into various useful steel materials. The really useless steel can also be made into various aggregates. For example, waste concrete blocks can be sieved to obtain coarse aggregates and fine aggregates. As coarse aggregates, they can be used as reinforcements for reinforcing foundations. Fine aggregates can be used as masonry mortar and mortar. Of course, these secondary manufacturing materials need to be completed through the use of a full set of production line processes such as jaw crushers, mobile crushers, and construction waste disposal equipment. As a result, the jaw crusher is so important. Zhejiang Shuangjin Machinery Group Co., Ltd. has just such a good jaw crusher.
