Roller press is mounted at +9.8m level floor in front of the mill and below mill hopper. Rollers are mounted on a steel frame bolted to reinforced concrete beam-column frames. Four reinforced concrete columns of size 800mm x 800mm in M-20 mix (28-day characteristic cube strength = 20 MPa) are provided upto +9.8m level only to support roller press floor.
As new-type and energy-efficient cement grinding machine, cement roller press has advantages of energy-saving, high efficiency, less steel consumption and less noise. Both apply for new cement plant building and old cement plant revamping. According to the data, roller press helps ball mill system to increase the output by 30-50%.
The most noticeable feature of the roller press cement pre grinding system is that the fine material power ground at the middle part of the roller will be sent to the ball mill for further grinding. The cement grinding process in this system is rather simple with less equipment required.
But for vertical roller mills, the growth rate of that of material will gradually decrease. From this point of view, roller press is superior to vertical mill. In roller press, the contact area between the two rollers and the material is small; the material is ground by only passing through the roller press once due to the large grinding ratio.
