The oil supply units for our vertical roller mill gear units and drive systems includes low-pressure pumps to feed bearings and toothings with filtered and cooled lubrication oil. If required high-pressure pumps supply the oil for the thrust bearing from a separated compartment of the tank filled with filtered oil from the low-pressure part.
Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.
The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding. Within the cement industry vertical roller mills are becoming more important as more cement producers look to increase their use of clinker substitute .
Based on screening analysis laser size analysis grindability and rigidity tests of samples collected on line from a cement and a power plant a simulation of the grinding process in vertical roller mills was carried out. The simulation calculation used a breakage function B. The results indicate that the breakage function B and the selection function S in the form of a matrix can be .
