CHAENG GRMS slag vertical roller mill integrates the functions of fine crushing, grinding, drying, powder selecting and conveying, with the advantages of high grinding efficiency, strong drying capacity.

1. Reduce investment costs, intelligent control

GRMS integrates the functions of crushing, grinding, drying, separating and conveying, with compact structure, covering an area of approximately 50% of that of ball mill system. And it can be laid outdoors, so that investment cost is greatly reduced; it is equipped with PLC/DCS automatic control system, can realize remote control and simple operation.


2. Adjust fineness according to demands

A new efficient cage-shaped rotor separator ensures the finished surface area can be adjusted flexibly in the range of 400~550 ㎡/kg, to meet customer different requirements on fineness.

3. Power consumption per set of GRMS is not more than 30Kwh

The horizontal grinding table and conical grinding roller are adopted to ensure the material to form a stable material bed. The energy consumption is low, saving 30% - 40% compared with the ball milling system;

Metal recovery rate of per-ton slag (%) 0.2-0.3 0.2-0.3 0.2-0.3

4. Remarkable energy-saving and environmental protection, convenient maintenance

The system is in the state of negative pressure, no dust overflow. Environment is clean, meeting the environmental protection requirements; through the maintenance of the oil cylinder, turning the rocker arm to replace the roller sleeve and lining plate is convenient and fast, so as to reduce downtime losses.

5. Original spare parts to reduce maintenance worries


Grinding rollers, rocker arms and other spare parts in the whole system are manufactured by CHAENG originally, ensuring the quality and greatly reducing the customer's worries of no where to find the spare parts.


6. Metal recovery rate of per-ton slag is great

Special design of the iron removal device can make pig iron recovery rate reach 0.2-0.3%, so that the per-ton production of slag can get higher metal income, and to avoid the metal "enrichment" phenomenon, reduce the consumption of wearing parts and decrease maintenance costs.


Referring to the investment income of GRMS46.41 made by CHAENG, it is can be known that annual benefits can reach 18,000,000 yuan.
