It falls on the table placed at the bottom of the mill. Due to the centrifugal force generated by the rotation of the main shaft the grinding rollers are pressed closely upon the grinding ring and grind the material fed into the mill (raw, cement or coal for instance) as they roll.John Frank
In July 2012, RWE Power in Essen commissioned a new vertical roller mill from Loesche (Fig.). The second coal mill was install in Ville/Berrenrath and should increase production of pulverized lignite dust at this location by 500 000 t/a. The plant mills dry lignite to grained fuel. The first preparatory work for construction of this.
Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.

1 Introduction. Two mill systems are employed for most coal grinding applications in the cement industry. These are, on the one hand, vertical roller mills (VRM) that have achieved a share of almost 90 % and, on the other hand, ball mills whose share decreased to just over 10 %. Gebr. Pfeiffer SE supplies stand-alone MPS.
Zhang et al. developed a nonlinear mathematical model for the normal grinding process of Vertical Spindle coal mills using on-site measurement data and an evolutionary computation technique in 2002 . A realistic technique for implementation of the model in real-time was demonstrated in 2006 [4,16]. Niemczyk et al.
APPLICATIONS. UBE Vertical Mill, having an advantage that drying, classification and pneumatic transportation can be carried out simultaneously with pulverization, is suitable for grinding of cement raw materials, coal, cement clinker, blast furnace slag and other material.

The POITTEMILL pendulum roller mill is a vertical mill that works by compressing the material bed. The pendulums mounted on a star wheel are driven by a vertical shaft. Each pendulum is fitted with a grinding roller that rotates upon its axis. The rotation of the star wheel combines with the articulation of the pendulum to.
Rollers and Table Segments: Both are cast in High Chrome Alloys in the range of 16% to 27 % with a 55-62 HRC hardness. The use of High Chrome increases the wear life versus low and medium chrome alloys. We are able to send to your plant site engineers and sales staff to re-engineer and/or draft your vertical mill.
