MR Series Grinding Mill
The MR Series Grinding Mill is Mingrun's high-efficiency, energy-saving powder making machine for non-metallic minerals in metallurgy, mining, building materials, power and chemical industries. It produces ground calcium carbonate, desulfurization limestone powder, coal powder, petroleum coke powder and more.
- Feed size
- ≤35 mm
- Capacity
- 2–30 t/h
Advantages
Stepped rollers and ring
Longer grinding time per pass for higher crushing efficiency.
High-density classifier rotor
Finer product and higher output at the same time.
High-efficiency centrifugal fan
Die-formed fan that outperforms conventional fans.
Easy fineness control
Adjustable classifier blade gap to set product fineness.
Working principle
After crushing, material is lifted to the hopper and fed evenly and continuously into the grinding chamber. Ground powder is carried by the airflow to the classifier; qualified fine powder is separated in the cyclone collector, while oversize particles fall back into the mill for regrinding. The airflow system works in a closed circuit for a clean working environment.
Applications
Metallurgy, mining, building materials, power, chemicals
Suitable materials
Limestone, calcite, dolomite, marble, talc, coal, kaolin, barite, petroleum coke, bauxite and more
