LM Vertical slag mill

LM Vertical slag mill, integrating drying, grinding, powder selection and conveying together, is a special equipment for grinding industrial waste into powder. It adopts a unique grinding device to achieve the integration of grinding and powder selection, focus on slag milling. The area is about 50% of the ball milling system. Energy consumption is 30% ~ 40% of the ball milling system.

Input Size

38-65mm

Capacity

7-100T/H

Applications:

It is widely used in the production of cement and concrete, as well as the recycling and milling of steel slag and water slag in steel plants.

Working Principle

The slag vertical mill is a negative-pressure air-sweep type grinding equipment, which dries the slag and grinds the slag. When working, the main motor drives the grinding table to rotate through the reducer, and at the same time, the hot air enters the body of the vertical mill from the air inlet, and the material falls from the discharge port to the center of the grinding table. In the area of the upper grinding roller, 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 material continues to move toward the edge of the grinding table until it is taken away by the strong air flow at the wind ring, and the larger particulate material falls back onto the grinding table to continue crushing. When the material in the air flow passes through the upper separator, the rotor under the action of the blades, the coarse particles are returned to the grinding table for grinding, and the qualified fine powder is discharged with the airflow and collected by the system's powder collector. The collected powder is the product of the vertical grinding.
