We all know that machinery and equipment such as sand making machine generate a lot of noise when they are working. Noise pollution is also a kind of environmental pollution. Noise not only plagues workers in frontline production but also affects the daily life of the surrounding residents. So how to effectively reduce the production process of sand making noise problems, is to lift you from the following aspects: 1, sand production process in the high-pressure, high-speed airflow by reducing the pressure drop and reduce the flow rate, or change the shape of the airflow nozzle to indirectly reduce the noise. 2. Controlling the use of additional barriers to prevent the spread of noise in the production line of sand making use of barriers such as earth slopes, woods, bushes or tall buildings that are not afraid of noise, preventing the spread of sound. The sand production line uses the directivity of the sound source to control the noise, such as venting the exhaust towards the wilderness or sky to reduce the impact on the surrounding environment. 3, the entire production line to take sand muffler, sound absorption, sound insulation, vibration isolation, vibration and other measures to reduce the noise from the source and transmission of noise. 4, the noise of the recipient's protection: take workers rotation homework, shorten the workers into the high noise environment working hours. Personal protection of workers, such as wearing headphones, ear plugs and other anti-noise supplies. 5, sand making daily maintenance, regularly check whether the parts are loose, aging, etc., to reduce the failure rate of sand making machine, and effectively reduce the noise due to equipment failure aging. Such as: sand work on the belt tensioning belt size should be properly adjusted so that the triangular belt force balance, dual motor drive, the triangular tape on both sides should be grouped matching, try to make the length of both sides consistent.
Sand making machine is widely used as a kind of mechanism sand equipment, which integrates sand making machine and plastic shaping, and has wide range of applications. It is especially suitable for aggregate sand production of various rocks in mine crushing. The rotor as a sand making machine "heart", the daily use of the need for regular maintenance and care. Heavy industry is summed up several factors affecting the sand making machine rotor and maintenance methods: 1, A direct factor of rotor damage is the loosening of the locating screw of the rotor core and the base of the sand making machine. To solve this problem, only the fastening bolts need to be fastened for routine inspection and maintenance. If it is found that the screw is missing, a tightening should be added. 2, sand making machine bearing on the rotor. Bearings and rotors are complementary, the bearing damage will directly affect the rotor's work, so if the bearings have problems immediately repair or replacement, so as to avoid greater losses. 3, the rotor rusty problem. We know iron is rusty, but we can do something to a lesser extent to reduce the frequency of rusting and increase rotor life. A good way to avoid rusting the rotor is to apply a layer of insulating varnish to the sand making machine. If it is found that the rusting area is sanded with sandpaper as soon as possible, the problem is small and needs to be polished in time. The rotor is a core part of the sand making machine and needs special attention. In order to make the sand making machine play its performance better, pay special attention to the daily maintenance and maintenance of the sand making machine equipment, so that the regular inspection, the damage of the damaged small parts should be promptly replaced, promptly handled, Production efficiency, prolong the service life of sand making machine.
Crusher market is not very booming now, the main reason is because our products are not new enough, not innovative. China's economy has always relied on exports, investment and consumption, especially investment, counterattacking the disintegration of construction waste crusher. Therefore, China's economy has been slowly facing a downturn. Foreign markets are getting bigger and bigger. First of all, we should actively respond to the development needs of our products and have a follow-up service to society and the market. This is also the future development of the crusher in the future. And then, our fine crusher manufacturers should unite as one, eliminate the outsourcing of products, give full play to their own advantages and conditions, and properly manufacture and manufacture all the crusher. Let our economy grow stronger. Now our crusher market is big but not strong. Find the cause should be completely radical. In the future development. Fine work with the hardness of the material, let our country grow stronger economy, such as artificial sand, raw materials of quartz glass raw materials processing, stone stone cement clinker production and other various mines, gravel plants, construction waste crusher, Metallurgical powder is not, the new building materials, refractory materials used in various sectors of the stone hardness.

Winter Raymond mill maintenance precautions: Yesterday, the beginning of winter, in this cold winter we should pay attention to warm clothes! The maintenance of a large raymond mill in the cold winter is also important and takes longer than in summer because the cement is completely solidified after the foundation has been treated. 1, the first winter roll assembly and some other parts of the refueling should be replaced by butter for winter, so that in the cold winter butter is not easy to freeze. 2, Second, when the boot can be preheated for 5 minutes, and then start feeding production. When the first open analysis machine boot, and then open the last fan to open the host. 3, in the winter monsoon is relatively large, outdoor dusting bag Raymond mill must be tight, do not loose, bag once a day beating, keep breathable. Bag is not breathable, Raymond mill is no production. Raymond mill plus use roller grinding, the principle of wind selection crushed material, so the use of wind is very crucial. The law of nature is to heat up cold shrinkage, this time Raymond mill screws can be tight again, the flange of the link must check the open seal is qualified to ensure that there is no place for gas leaks. In addition, some users will ask Raymond mill output will be higher than usual production, is not the principle of thermal expansion and contraction, the winter material is more brittle and easier to process it? My company's Raymond mill engineer said the winter Raymond mill boot maintenance should pay more attention than in summer, especially Raymond mill in the outdoor processing of materials users should pay attention to Raymond mill maintenance, butter is best to use Winter-specific, general butter winter is not easy to get into, the roller assembly will wear more powerful.
Vertical roller mill (referred to as vertical mill) and raymond mill grinding mechanism similar to all belong to the rolling crush, which is destined to produce less than the amount of fine powder per unit time. As the roller pressure is used hydraulic method, the roller pressure roller material greater, so the grinding efficiency is much better than the Raymond mill. Initially, vertical mill are two roller structure, mainly used for the production of 400 meals the following meal. In order to improve the content of fine powder per unit time, three-roll vertical mill was developed later, and the content of fine powder has been greatly improved, but generally, the products below 1000 heads are still mainly produced. Later, some people on the upper classifier has been transformed, can be directly produced 1250 mesh powder. The use of the raymond mill out of the 600 head -1000 head products, the other with ultra-fine grading machine for second grading, can produce more than 1250 heads of products. At the same time, the equipment system investment cost is too high. Vertical mill R & D and production of high technical requirements, China's relevant research institutes in the 1980s proposed to vigorously promote the legislation in the cement industry legislation, and when there are some manufacturers have introduced their own vertical mill products. However, at the time of the limited research and development level, vertical mill products at this time had unavoidable technical defects. Therefore, many cement manufacturers finally switched to ball mill again. In recent years, with the R & D and development of milling machinery increased dramatically, vertical mill technology of foreign mill manufacturers has matured, vertical mill product technology advantages have become increasingly prominent. In this situation, the domestic manufacturers of milling machines to learn from the successful experience of foreign countries for major technological reforms, but also have re-launched with their own patented technology vertical mill products, and gradually accepted by the domestic cement, electric power, chemical industry , Become the preferred equipment grinding industry.
