Vertical raw mill is one kind of raw mill, generally used to grind bulk, granular, and powder raw materials into required cement raw meal in the cement manufacturing plant. Vertical raw mill is an ideal grinding mill that crushing, drying, grinding, grading transfer set in one. It can be widely used in cement, electric power, metallurgy, chemical industry, non-metallic ore, and other industries.

Features

1. High grinding efficiency and low power consumption. This kind of machine consumes 20-30% lower power. And with the growing of moisture content, its energy-saving effect will be more obvious.

2. Strong dry ability. Air is used to send materials, and the temperature of the air can be controlled according to the moisture content of materials.

3. Large feeding size. The feeding size can be as large as 5% of the diameter of the grinding diameter, that is, 40 to 100mm. Therefore, secondary grinding is unnecessary for large-scale and medium vertical mill.

4. Stable chemical composition and even particle size products.

5. Simple process flow and small in size. There is a segregator in the cement vertical raw mill, which makes powder separator and elevator unnecessary. Grinded dusty air can directly enter into the environmental protection equipment.

6. Low noises, few dust, and environment friendly. There is no direct contact between the grinding rollers and grinding disc, so there is no impact sound caused by the colliding between the steel balls or between the steel ball and lining plate.
