In the mine operation, what is the crushing mode of the gravel production line and the crusher. Stone crusher, also known as crushers, are widely used in many departments such as mines, smelting, building materials, highways, railways, water conservancy and chemical industry. At present, the commonly used macadam machines include jaw crusher, impact crusher, hammer crusher, hydraulic cone crusher, macadam production line, stone production line, etc.
According to the process requirements, the gravel processing system is composed of coarse crushing workshop, screening, medium crushing, mud washing, finished product silo, finished product feeding system, water supply and drainage system, power supply and distribution system and corresponding auxiliary facilities. The workshops are connected by belt conveyor. The pollution source treated by the dust removal system in the gravel production line is mainly the dust generated during crushing, screening and transportation, so as to achieve a cleaner production environment. The commonly used dust removal technology can clean the dust generated in production, and build a new environmentally friendly gravel production line,as a new type of gravel production line, environmental friendly gravel production line has been built in many places. The design of dust removal system on environmental friendly gravel production line plays a very important role in the overall environmental protection production.
In the selection of dust collector equipment, we can try to choose dust collector equipment with high dust removal efficiency and no blockage of filter bags, and frequent maintenance of dust collectors can greatly improve the working efficiency of dust collectors and the cleanliness of the production environment.This system process design, considering the whole of the goupitan project required artificial various requirements of crushed stone, concrete construction should not only meet the needs of the peak intensity of production, and considering the operation economy of the slack time production, and focus on the system operation reliability and economy of for a long time in process design and equipment selection configuration given full consideration.
The key equipment of the macadam processing system adopts the internal and external equipment with good technology, reliable quality and large single machine production capacity to ensure the reliability of the long-term operation of the system. At the same time, the production capacity of the system has relatively large adjustment space, the macadam production adopts a relatively technological process, the discharge chute of the first and third screening workshops is controlled by a flap door, which can flexibly adjust the production and distribution of finished aggregate to meet the needs of concrete. Referring to the dehydration treatment process of finished sand in Ertan, Xiaolangdi and other hydropower station projects, the method of combining mechanical and natural dehydration is adopted, with small land occupation and fast dehydration speed, ensuring the stability of water content of finished sand. In addition to the small stone silo, the finished crushed stone silo is equipped with a slow-down device to prevent the aggregate from being broken again, and the product quality is improved.
