Feeding sizes: ≤15-≤25mm
Production capacity: 0.6-52 t/h
Applicable materials: Limestone, calcite, calcium carbonate, dolomite, barite, talc, gypsum, diabase, quartz, bentonite, etc.
Applications: Calcium carbonate crushing and processing, gypsum powder processing, power plant desulfurization, non-metallic mineral milling, and pulverized coal preparation.

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.
