Loesche Drive Selection for Large VRMs

2017-8-12  1 A background to drives of vertical roller mills The drive of a vertical roller mill – essentially the mill gearbox – has to fulfill two tasks: The first is to reduce the speed of the electric motor to the selected mill speed and to transmit the torque created by the motor. Secondly, the gearbox has

Modeling Vertical Roller Mill Raw Meal Residue by ...

2019-6-30  Abstract: This study proposes a method for modeling the Vertical Roller Mill (VRM) to predict residue 90 micron and residue 200 micron of the raw meal product using Back Propagation Neural Network (BPNN). The modelling step is input preparation, Artificial Neural Network (ANN) structure determination, optimizer and loss function selection, training ANN and model evaluation.
