Bauxite Grinder Roller

Bauxite Grinder Roller supplier AGICO CEMENT CHINA told cement plants how bauxite hlm vertical mills can increase production.

The bauxite hlm vertical mill is mainly driven by a motor to drive the reducer to drive the grinding disc to rotate. The material to be ground is fed into the center of the rotating grinding disc by the air lock feeding equipment. Under the action of centrifugal force, the material moves to the periphery of the grinding disc and enters the grinding roller. road. Under the action of the pressure of the grinding roller, the material is crushed by extrusion, grinding and shearing.

What are the main ways to increase the production capacity of bauxite HLM vertical mill?

(1) Add scraper

The scraper plate is added to ensure that the material in the center area of ​​the grinding disc is leveled, and a stable material layer is formed to avoid material accumulation and improve production capacity.

(2) Hydraulic system pressure

The grinding pressure is proportional to the output. We can appropriately increase the positive pressure of the material on the grinding disc, thereby increasing the grinding efficiency. However, it should be reminded that if the pressure is too high, the motor load will also increase, which will affect the life of the whole machine. Therefore, we must consider the problem of equipment life while increasing the production capacity.

(3) Enhance the grindability of materials

Material fineness, humidity and hardness are all important factors that affect the production capacity of bauxite hlm vertical mill. Usually, bauxite is not a big raw material. When grinding, we mainly reduce its humidity to avoid water entering the mill. The feed tube is clogged. Increase its dryness, thereby increasing productivity.

(4) Increase the differential pressure

The pressure difference in the mill and the pressure difference between the two parts of the bag collector directly affect the product quality and output. The pressure difference inside the mill refers to the local ventilation resistance caused by the hot air nozzle ring entering the mill and the fluid resistance of the suspended material between the top of the nozzle ring and the pressure point. The size of the pressure difference of the bag collector directly affects whether the finished product can be collected well after the material is discharged. Therefore, real-time monitoring of the pressure difference is also a crucial link.
