used coal preparation equipment

Natural sand resources can not meet the need and therefore the importance of the manufactured sand is growing.

Using used coal preparation equipment to make sand, sand production rate is high, products grain shape is good and production costs is low with small amount of construction and installation works.

used coal preparation equipment has a variety of models and operating modes, the selection of is the model is the first problem to be solved and it must be weighed from both the quality of products of sand making and the cost of sand making.

The material has been crushed are discharged from the discharge port in the lower position and forms a closed circuit with circulating screening system and generally after three times of circulation materials can be crushed into products that are lower than 20 mesh.

In the whole crushing process, material impact and crush with each other and does not directly contact the metal components, but to make impact, friction and grinding with materials lining, which reduces the angle pollution and extends the mechanical wear time.
