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

Vertical abrasive bed grinding after years of development, 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.

Vertical mill these advantages gradually be applied to pre-grinding system. CHAENG launched by the GRM series vertical mill and the ball mill pre-grinding system supporting material before entering the tube 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 for the vertical mill pre-grinding mill system and traditional ball mill ?

CHAENG for cement plant launched GRM series cement vertical mill pre-grinding system, with the traditional vertical mill 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 vertical 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, grinding table, grinding roller, hydraulic equipment, lubrication devices and other components. Cement clinker enters through the inlet valve is central Grinding Table, since the Grinding Table 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.

Vertical mill pre-grinding system application

Indonesia cement plants use CHAENG’S vertical roller mill pre-grinding system, the production of cement grade P.O42.5 system capacity 180t / h-200t / h, the system grinding energy 32kwh / t or so.
