LM vertical coal mill

LM vertical coal mill, also known as medium-speed coal mill, realizes the domestic large-scale high-end vertical coal mill. LM vertical coal mill system can be drying and grinding at the same time, can realize drying while grinding.

Input Size

<50mm

Capacity

5-100T/H

Applications:

It is widely used in power plants, thermal power plants, cement plants, steel plants and other industries that require pulverized coal fuel and desulfurized stone powder.

Processed Materials:

calcite, dolomite, barite, talc, calcium carbonate, bentonite, slag, etc.

1.High grinding efficiency

High grinding efficiency and low energy consumption, saving 40% -50% power consumption compared to ball mill

2.Low overall investment cost

It integrates crushing, drying, grinding, powder selection and conveying into one, with simple process flow and compact layout

Working Principle

The main motor drives the grinding table to rotate through the reducer, and at the same time, the wind enters the mill from the air inlet. The material falls through the screw feeder's discharge port and falls in the center of the grinding table. When grinding the roller table area, it is crushed by the grinding roller, and the bulk material is crushed directly, and the fine-grained material is extruded to form a material bed for inter-particle crushing. The crushed materials continue to move toward the edge of the grinding table until they are taken away by the strong air flow at the wind ring, and the larger granular materials fall back onto the grinding table to continue crushing. Under the action of the blade, the coarse particles are returned to the grinding table for grinding. Qualified fine powder is discharged with the air flow and collected by the system's powder collector. The collected powder is the product of the ultra-fine vertical grinding.
