Semi-finishing grinding system: after ground by cement roller press, materials are divided into three parts through an air classifier: coarse, medium and fine, in which the coarse material is returned to the roller press for re-grinding, the medium material is put into a ball mill for further grinding, and the fine material is directly discharged as the finished …
The roller mill's ability to reduce materials to a uniform particle size provides more control of product characteristics and minimizes waste, as shown in Figure 1. The mill's controlled reduction action requires less energy than other grinding methods, improving production effi-ciency and saving energy dollars. Roller mill components and ...

Designed for granulated blastfurnace slag (GBS), this roller press remains in operation. However, roller press design has been adapted to grind raw materials, cement and slag as part of a continuous process to improve and extend its use. Today it remains the most cost-efficient comminution method.
The high-pressure grinding roll has proven to be extremely effective for the grinding of mineral raw materials. With numerous POLYCOM® installations in different industrial sectors, ThyssenKrupp Industrial Solutions is the worldwide market leader for this technology. Thanks to the application of ultramodern production processes, the plants …
This roller press can improve the grinding capacity by 50- compared to ball mill systems and reduce the power consumption of the grinding system by 30-40%, and 20-30% that of finished cement. The squeezed materials is easy to grind and 0.08mm fine material accounts for 30-30% and material smaller than 20 mm accounts for 65-85%.
F.L. has developed this cement grinding system which is a fully air-swept ring roller mill with internal conveying and grit separation. This mill is a major improvement of the cement grinding systems known today which are ball mill, roller press (HPGR)/ball mill, vertical roller mill and closed-circuit roller press for finish grinding.
The high-pressure grinding roller press (HPGR) is centered around two counter-rotating rollers. These are supported in the frame by spherical roller bearings that are inherently self-aligning and extremely robust.
