Aug 171971 encompasses production of both portland and masonry cementis shown in Figure 11.6-1. As shown in the figurethe process can be divided into the following primary components: raw materials acquisition and handlingkiln feed preparationpyroprocessingand finished cement grinding. Each of these process components is described briefly below.
When grinding cementthe ball mill has a yield of 3001000gtand the grinding system of the roller press has a yield of 0.5gtso it can meet the requirements of white cement. Low noise. The ball mill noise is above 110 dBwhile the roller press is about 80 dB.
Closed-circuit Grinding System. The closed-circuit grinding system of the ball mill is shown as follows: materials mixed in a certain proportion will firstly enter the cement ball mill for grinding and then be sent to the powder concentrator by bucket elevator. The powder concentrator divides the materials into coarse and fine materials.
The size of the grinding material is largethe system air volume is insufficientthe grinding pressure is lowthe system leaks airthe material layer is unstablethe material ring is lowand the roller surface or the grinding disc wears seriouslywhich will cause the grinding machine to slag more.
