Energy Saving Low Consumption Limestone Vertical Mill 45t/H

Energy Saving Low Consumption 45t/h Calcium Carbonate Grinding Equipment/Limestone Vertical Mill

Description

Limestone vertical mill integrates fine crushing, drying, grinding, powder selection, and transportation, without the need for additional drying, powder selection, and lifting equipment. The dust containing gas from the grinding can be directly collected by a high concentration bag dust collector or electric dust collector, with a compact layout and can be arranged outdoors. The building area is about 70% of the ball milling system, and the building space is about 50-60% of the ball milling system. Therefore, its simple process flow, small footprint and occupied space make the construction cost low.

The vertical mill motor drives the grinding plate to rotate through a reducer, while hot air enters the vertical mill from the air inlet. The material falls into the center of the grinding plate from the discharge port. Due to centrifugal force, the material moves from the center of the grinding plate to the edge of the grinding plate. When passing through the annular groove on the grinding plate, it is crushed by the grinding roller, and the crushed material continues to move towards the edge of the grinding plate until it is carried away by the airflow at the wind ring, And the large particles of material fall onto the grinding plate and continue to be crushed.

When the material in the airflow passes through the upper separator, under the action of the guide vanes, the coarse material falls from the cone bucket onto the grinding plate, and the fine powder is discharged from the mill along with the airflow, collected by the system's dust collector. The collected powder is the product produced by the vertical mill. The material is dried during contact with the gas in the shell to achieve the required dryness and humidity of the product. By adjusting the angle of the separator guide vanes (not adjustable for small vertical mills) and the speed of the separator rotor, the required fineness of the product can be achieved.

Working principle

The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing water are dried in the Contact process with hot gas to meet the required product moisture.

Product advantages:
1. More obvious energy-saving effect
Due to its advanced concept, simple process, and small installed capacity, the desulfurization limestone vertical mill can save 45% to 60% of electricity when grinding ultrafine limestone compared to traditional tube grinding systems.
2. High grinding efficiency
By hydraulic pressure boosting, the grinding force can be increased, thereby increasing production and improving grinding efficiency. At the same time, there is also a limiter device that only grinds the material to prevent accidental contact between the grinding roller and the grinding ring from causing equipment vibration or even wear.
3. Equipment is environmentally friendly, with low noise, less dust, and a clean operating environment

In the operation of a vertical mill, the grinding roller and grinding disc do not directly contact each other, and there is no metal impact sound of steel balls colliding with each other or hitting the lining plate in the ball mill. Therefore, the noise is low, which is 20-25 decibels lower than that of a ball mill. In addition, the vertical mill adopts a fully sealed system, which operates under negative pressure, without dust, and the environment is clean.
