Raw Mill for Mineral Processing

Raw Mill Introduction

Raw mill is mainly used in grinding raw materials and end products in cement plant. It is also suitable for various ores and other materials metallurgy, mine, chemical and construction. Besides, it has two forms of milling, one is an open form, and the other is a recycle close form equipped with powder concentrator. It is widely applied in many industries and has convenient operation.

In cement plant, After being sintered in the kiln, clinkers are cooled and then conveyed to the hopper. They are then fed, by the metering feeder, to the horizontal raw mill. The clinkers preliminarily crushed here are fed to the finishing mill, and finely powdered before being fed to the separator.

  • High responsibility to the material blending system (because of the short material residence time in the crusher)
  • Can dry the material with kiln exhaust gas while milling it.
  • Small footprint and low noise
