Chaeng (Great Wall Machinery )GRM series vertical mill pre-grinding Introduction

Vertical roller mill develop many years , through continuous improvement summary and, at present, the technology is mature and stable, with a good grinding effect, running high efficiency, low maintenance costs, power consumption and small significant advantages.

These advantages of Vertical mill gradually is applied to pre-grinding system. Great Wall Machinery launched by the GRM series vertical mill and the ball mill pre-grinding system supporting material before entering the ball mill, vertical mill adopts continuous rolling of the material pre-grinding, its unique design and roll grinding material layer technology, effectively reducing the feed size. At the same time, rolling the material after the increase micro-cracks, grindability, and can improve overall system capacity by 50% -100% 10% -25% node.

What is the difference of Vertical mill pre-grinding mill system and traditional ball mill ?

Great Wall Machinery for cement plant launched GRM series cement vertical mill pre-grinding system, with the traditional vertical machine is different is that the abolition of internal device separator, and fan. What good is it?

1, the abolition of separator and blower, etc. in the vertical mill system can be reduced approximately 50% of the installed power.

2, the roller mill and ball mill grinding system consisting of a pre-open pre-grinding, circular pre-grinding, mixing grinding, combined grinding systems, production increased by 50% -100%, to achieve energy saving and efficient grinding Yield lower consumption targets.

working principle

Vertical mill pre-grinding system consists of motor, reducer, disc, roller, hydraulic equipment, lubrication devices and other components. Cement clinker enters through the inlet valve is central disc, since the disc rotation generates centrifugal force, the material thrown into the grinding zone by pressurized grinding rolls and grinding the material for extrusion. Material crushed through the outer ring of the disc, fall within the lower part of the mill housing, scraper plate is scraped into feed downpipe discharge.
