Mining machinery operation is used in mining, beneficiation and so on. It has a very important position in the development of national economy. It is one of the important equipment manufacturing industries to provide equipment for the mining and processing of solid raw materials, materials and fuels. Usually serves in black and non-ferrous metallurgy, coal, building materials, electricity, chemical, nuclear industry and other important basic industrial sectors. The processed products are also widely used in the basic construction of transportation, railway, construction, water conservancy and hydropower.

       The main process of mining includes the stone and sand crushing production. More about the stone crushing equipment, usually, including the following parts:

        Feeding system:

        Usually, one stone crushing line adopts truck delivery the materials to hopper, then trough the vibrating feeder delivery the materials continuously, uniformly and stably to crushing equipment for crushing.

       Crushing system:

       The crushing system is the main part of a stone production line, which is generally divided into coarse crushing, medium crushing and sand making. Coarse crushing is the Primary crushing, usually using jaw crusher. Medium and fine crushing is secondary and third crushing, usually using cone crusher, impact crusher, if the raw material is granite, basalt, river pebble and other high hardness stone, cone crusher suitable for the secondary crushing, if the raw material is very hard with high capacity demand, single cylinder hydraulic cone crusher and Multi-cylinders hydraulic cone crusher suitable, which can improve the production capacity of complete crushing line. If raw material is limestone, calcite and other low hardness stone, the secondary crusher can use impact crusher. The raw material be fed into jaw crusher crushing by vibrating feeder, material after coarse crushing, be delivery to secondary crusher by belt conveyor for crushing again, the products after crushing, be delivery to vibrating screen for separating, the bigger size material be delivery to crusher for crushing again, forming a closed circuit for multiple cycles.

       Sand making system:

       After crushing by cone crusher, impact crusher, can get different size stone. If want to get sand, can match a sand making machine after secondary crusher. If choose dry processing, can match a classifier and pulse dust filter to separate the coarse and fine powder. If choose wet sand making is used, the material that meets the particle size requirement of the finished product is sent to the stone washing machine for cleaning, and the finished product conveyor belt is output after cleaning.
