Brief Introduction

Vertical roller mill is called vertical mill also. FTM new type vertical mill is developed on the basis of many years of production and development of pulverizers, analyzing and studying the advantages and disadvantages of similar products at home and abroad. The vertical mill adopts advanced material bed grinding and partial external circulation technology, which integrates grinding, grading, drying and conveying. This large-scale advanced high-yield energy-saving grinding product has become the mainstream equipment in the milling industry.

It is suitable for---barite, calcite, potassium feldspar,talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, cement, phosphate rock, gypsum, etc。

Working Principle

The main motor drives the grinding disc to rotate through the reducer, and the fixed grinding roller rotates along the raceway of the grinding disc. The material falls from the feeding port to the center of the grinding disc. Under the action of centrifugal force, the material moves from the center of the grinding disc to the edge at a constant speed. When passing through the grinding raceway, it is crushed by the grinding roller. The grinding force is provided by the hydraulic loading system. The material is directly crushed, and the fine-grained material is squeezed to form a material bed for intergranular crushing.

Drying and grinding are carried out at the same time. The primary hot air enters the surrounding of the grinding disc evenly through the air ring, and the pulverized materials thrown out tangentially from the grinding disc after grinding are dried and transported to the upper powder separator. Under the action of the rotor blades, Coarse particles return to the grinding table for grinding (internal circulation), and the qualified fine powder is milled together with the airflow, and is collected by the system powder collector, which is the finished product.
