wear rate of roller press cement mill

Cement Roller Press, Roller Press In Cement Plant AGICO ...

When grinding cement, the ball mill has a yield of 300~1000g/t, and the grinding system of the roller press has a yield of 0.5g/t, so it can meet the requirements of white cement. Low noise . The ball mill noise is above 110 dB, while the roller press is about 80 dB.

Cement Roller Press - Roller Press In Cement Plant ...

Cement ball mill is a main cement grinding mill with a low energy utilization rate (only 3%-5%). Compared with the grinding energy consumption, most of its energy is consumed by collision heating and noise. Therefore, we usually adopt the cement roller press to replace the fine crushing and coarse grinding role of the ball mill. This increases the output of the ball mill system by 30-50%, and 20-35%

16/11/2015  The actual wear rate for both the roller and table liners before hardfacing was 0.30 g/T. The measured wear rate with hardfaced liners was 0.12 g/T. The 50% reduction in wear rate with hardfaced liners was expected as data from other vertical cement mills indicated such a savings could be expected. In either case the wear rate has exceeded expectations and operation has not been detrimentally

Ball Mills Or Vertical Roller Mills: Which Is Better For ...

The rate of wear is greater in a ball mill but the cost of replacement is lower. On the other hand, the wear rate is lower in VRM, the cost of replacing the parts is significantly higher. Product Quality. When VRM was first mooted as an alternative in cement production, one of its seeming challenges was its particle size distribution (PSD). Due to their high separation efficiency and its high circulation factor, VRM tends to produce cement
