Product Introduction

The High-strength Grinding Mill produced by Henan Zhongde Company is widely used for crushing and high-fine powder processing more than 280 kinds of materials like barite, limestone, ceramics, slag, other non-flammable and explosive mines, metallurgy, chemicals, building materials, etc whose Mohs hardness is not more than 9.3, and humidity is below 6%. The finished particle size adjust in the range of 80-425 mesh (the smallest is 1000 mesh).

  Through the special device added in the machine, it can produce 30-80 mesh of coarse powder. High-strength Mill is also called High-efficiency Mill, Hanging- roller mill or Ore Grinding Equipment.

Advantages of High Strength Grinding Mill:

1. Three-dimensional structure, small occupied area, strong quality of complete sets. It is an independent production system from the block material to the finished powder.

2. Uniform-fineness finished powder, 99% screening rate, which is difficult for other milling equipments to possess.

3. The gearing adopts a closed gearbox and pulley which transmit smoothly, and operates reliably .

4. All important parts adopt high-quality steel, and all wear-resistant parts adopt high-performance wear-resistant materials. The whole machine operates reliably with high –performance wear-resisting property.

5. The electrical system adopts centralized control, the milling workshop can basically achieve unmanned operation, and it is easy to maintain.
