LM Vertical Mill

Good environmental effect,High drying efficiency, Low running cost

Applications: Cement, coal, power plant desulfurization, metallurgy, chemical industry

Overview

it is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality. It is equipped with one device,which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration.
