Raw Mill

Coal mill is an important auxiliary equipment for coal-powder furnace

Raw Mill Is Widely Used In Cement Plant

Raw mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding.

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.

Zenith's raw mill also have small ones, which offer an ideal choice for those cement producers who seek cement raw mill for rent or sale.

Raw Mill Main Benefits And Features

  1. Strong adaptability.
  2. Continuous production.
  3. Large crushing ration.
  4. Easy to adjust the output product's size.

How Does The Raw Mill Work?

The raw mill uses pressure and shear generated between the rollers and the rotating table to crush and grind raw materials. Feed material is directed onto the grinding table by the feed chute. The rotation of the grinding table accelerates the material towards the grinding track and passes it under the rollers. Partially ground material passes over the dam ring encircling the grinding table and into the hot gas stream coming from the nozzle ring.
