Dry process clinker grinding ball mill for cement production

 1.Introduction of cement clinker grinding ball mill

This series of cement clinker grinding ball mill is suitable for cement,ore dressing, chemical and refractory industry to operate fine grinding.Bearing-type drive cement clinker grinding ball mill is a technological changing type, compared with the traditional grinding ball mill ,15% lower operating current and reduce the starting current 50%, according to Babbitt burning, downtime, the phenomenon of stopping production, not enough to improve the ball concentricity, run instability, current fluctuated,  wear serious phenomenon hollow shaft. While use of rolling bearing, the hollow shaft can continue to use, save 90% lubrication oil, improve the loading of 20%, increase production by 15%, 10% speed increase , each saving at 20%-30% power.

2.Working priciple of cement clinker grinding ball mill

1) This cement clinker ball mill,a horizontal type and tubular running device, has two chamber. This machine is grid type. The material enters first warehouse spirally and evenly along the input material hollow axis by input material device.

2) The cement clinker grinding ball mill is usually divided into at least two chambers,(Depends upon feed input size presently mill installed with Roller Press are mostly single chambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter). Ball diameter here is in the range 60–80 mm. In a two-chamber mill, the media in the second chamber are typically in the range 15–40 mm, although media down to 5 mm are sometimes encountered. As a general rule, the size of media has to match the size of material being ground: large media can't produce the ultra-fine particles required in the finished cement, but small media can't break large clinker particles.
