If you still have questions about the cement grinding system, or are interested in something ...
These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive wide acceptance.
This roller press can improve the grinding capacity by 50-100% compared to ball mill systems and reduce the grinding system’s power consumption by 30-40% and 20-30% of finished cement. The squeezed materials are easy to grind, and 0.08mm fine material accounts for 30-30%, …
The roller press is often used where energy-efficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles (microscopic cracks), so that the subsequent fine grinding is easier. When used as a pre-grinding system in ball mill circuits, production increases of ...

Vertical roller mills are adopted in 20 cement plants (44 mills) in Japan. Results Table Energy saving effect of the vertical roller mill Ball mill Specific power Cost estimation About 14million US$ [Newly-built] and about 230 million US$ [retrofitted], including the cost of supplemental facilities [200t-RM/h] [1US$=¥110] Related matters References Fig.1 Vertical roller mill Vertical roller ...
This cement mill roller press can be used for the grinding of raw materials, clinker, slag and steel slag in cement production lines, as well as industries like mining, steel, chemical, electricity, metallurgy, etc. Working Principle The roller press is designed according to the principle of material bed grinding. The rotation of the roller is achieved by the drive. The material from the ...
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.
