Disadvantages: the heat consumption of the wet process is too high, usually between J/kg and the consumption of ball mill vulnerable parts is also large. Compared with other processing methods, the clinker manufactured by the wet process has a low temperature when it comes out of the kiln, so this method is not suitable to produce the ...

suit all mill OEM's. Key benefits. Cement grinding. The feed for a cement grinding unit will normally be dry and. needs to be ground to a high degree of fineness. To achieve this efficiently, most mills will be split into two chambers. The first is set up for coarse grinding with a target to grind the feed materials down to around 1 mm.

Closedcircuit ball mills have been operated for cement milling for decades [[7], [8], [9]].Fig. 1 shows the process flow of a closedcircuit, twocompartment cement ball mill. The closedcircuit operation helped to reduce overmilling of particles [10], resulting in lower specific power consumption [11] in comparison with opencircuit operation, where the ball mill is operated without the ...

Indeed, according to Boulvin et al. [44], experimental data from a grinding circuit show that mill throughput impacts the separating curve. A recent experimental study on parameters affecting the VRM performance shows a correlation between product fineness and dynamic separator speed, mill throughput, and the rollers hydraulic pressure applied to the grinding table of the VRM [45].

Material is directly conveyed to the silos (silos are the large storage tanks of cement) from the grinding mills. Further, it is packed to about 2040 kg bags. Only a small percent of cement is packed in the bags only for those customers whom need is very small. The remaining cement is shipped in bulk quantities by mean of trucks, rails or ships.
