1.improve the efficiency of next process; 2.enhance the economic benefit; 3.wide range of applicable.

description 

  Primary machine is mainly used for lean ore enrichment, also called roughing, such as ore grade is 3%-5%, use of the machine can be thrown to a primary election, more than 70% of the waste rock and magazine, can make the magnetic iron grade reaches 20-40%, equivalent to the poor become rich.

  

  It can effectively improve the procedure efficiency or reduce transport costs, greatly reduces the cost of production (ball mill can improve the efficiency of 5-8 times), so as to achieve the goal that raises economic benefits.This machine is optional, lean ore tailings, river sand, sand, slag, fly ash and so on, have a very good effect.
