Process introduction

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

 

The slag(slag product applications) materials continuous moving to the outer edge of the grinding plate, off the grinding plate materials rising with the hot air which enter from wind ring into the vertical roller mill, through the vertical roller mill shell into the middle of the separator, in this course materials and hot gas got a fully heat exchange, the water quickly evaporates.

 

Separator controls the finished product output size, greater than the specified size are separated and fall back to the plate, while meet the fineness demands are brought through the separator into the finished product warehouse.

 

Slag Vertical Roller Mill
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 *0% 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 **0~**0 ㎡/kg, to meet customer different requirements on fineness.

3. Power consumption per set of GRMS is not more than *0Kwh

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 *0% - *0% compared with the ball milling system;


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.**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.
