Working principle of vertical roller mill

vertical roller mill drive motor through reducer rotating disc, the material falls from the mouth feed the central disc, while hot air from the air inlet into the mill, under the centrifugal force, the material to the disc edge moving through the circular groove on the disc is subject to Roller The rolled and crushed, after crushing the material in the disc ring at the edge of the wind with a high-speed airflow, the large particle goes straight into the disc to re-grinding, the material flow through the separator, the rotor rotating under the effect of coarse powder falls disc re-grinding, qualified with a fine powder with the air current mill, powder devices in debt collection, represents the product. Water containing materials in contact with the hot gas was the process of drying, to achieve the required product water.

1. vertical roller mill operating cost is low ;

vertical roller mill grinding, high efficiency, low power consumption, and the ball compared to 40 ~ 50% reduction in power consumption.

Less wear, roller sets, lining with special material, long service life, reduce operating costs.

Can be equipped with an external loop devices can further reduce power consumption.

2. vertical roller mill building low-cost,

vertical roller mill system can be reduced compared to an area of about 50%, construction costs reduced by about 70%.

As the set of broken, drying, grinding, grading conveyor in one, the system simple, open-air layout, so the building of low-cost.

3. vertical roller mill operation easy and reliable

Equipped with automatic control device, can realize remote control, easy to operate.

Equipped with a roller to prevent direct contact between the liner and the disc device will not be disruptive severe vibration.

4. vertical roller mill easy maintenance

Through the maintenance of tanks, turn rotating arm, roller sets, lining in a very short period of time can be more
Change.

5. vertical roller mill less pollution

Little vibration, low noise, negative pressure system is in operation, no dust spills.

6. vertical roller mill product quality and stability

Material stays in the grinding time is short, easy-to-particle size and chemical composition of the product testing and control, product quality is stable.
