Vertical Roller Mills

Process

CHAENG, as a professional vertical roller mill manufacturer, has a variety of VRMs for sale, which can be divided into GRMR Vertical Raw mill, GRMS Slag Vertical Mill, GRMK Vertical Cement Mill, and GRMC Vertical Coal Mill according to different grinding materials. 

CHAENG GRM series vertical roller grinding mill is mainly composed of separator, grinding roller, rocker arm, grinding table, transmission device, lubricating device, hydraulic pressure device and so on. It has the integrated functions of grinding, drying, powder selecting and conveying, with innovative technologies of high grind efficiency, strong drying ability, low noise, low power consumption and simple process. GRM vertical roller mill is innovative, environmental friendly and efficient, and it has won a number of Chinese technical patents. Especially, The new “one mill, three uses” vertical mill developed in 2015 by CHAENG led Chinese vertical roller mill development to a high peak.

The material through the feed tube fell into the center of the slag vertical roller mill and then the materials outwards the surrounding area of the grinding table at centrifugal force, to form a certain thick layer of materials bed, at the same time, the material was crushed by the vertical mill grinding rollers.

The slag(slag product applications) materials continuous moving to the outer edge of the grinding table, when the material leaves the grinding table and encounters the hot gas entering the mill through the air ring and it will rise into the middle of the separator, in this course materials and hot gas got a fully heat exchange, the water quickly evaporates.

The separator controls the finished product output size, particles larger than the specified size are separated and fall back to the grinding table, and the materials that meet the fineness requirements enter the finished product warehouse through the powder separator.
