The crushing process of the traditional crushing process has a large particle size and it is difficult to implement the energy saving principle of more crushing and less grinding. The process features are: high energy consumption, long process. In general, the crushing operation requires the use of two or more pieces of broken to get the ideal product size, this will result in an increase in the number of pieces of equipment crushing plant area increases, virtually increase the capital investment. Therefore, the design process using large, high crushing equipment is the development trend of crushing process.

In the mining process, the moisture content of the material seriously affect the mineral processing equipment dressing speed, crushing quality, excessive water content can make some equipment blocking material, sieve mesh sieve blockage, affecting the quality of the product, and even make a production line Stop working, bring huge losses to the production work. Mining equipment in the mineral processing process, the mine equipment for water treatment is very important part of the process, the mining equipment for dehydration of minerals are generally by mechanical gravity, pressure, centrifugal force is to make the water out of water or drying equipment to make the water evaporation , To achieve the purpose of dehydration. The reason for the mineral dehydration process for specific reasons are the following:

1.From the metallurgical point of view, concentrate dehydration on smelting is also very necessary, the greater the moisture content of concentrate not only increase the energy consumption of smelting, metallurgical furnace and will also reduce the application coefficient. In addition, the de-watering of mineral processing products is also required in order to enhance environmental protection or to reduce fresh water consumption in areas where water resources are scarce.

2.In the cold area, the storage and ransportation of concentrates containing a large amount of water will freeze up and become more and more unfavorable to the transportation of concentrate.

3.From the transport point of view, the need to stop dehydration concentrate products, or concentrate transport is very difficult, but also to increase transport costs.

4.Not just concentrate dehydration disposal, as on the tailings as well. Tailings often contain more than 70% moisture and are generally dewatered before they enter the tailings pond.
