Vertical Roller Mill Training by PAIThis video was made by PAI which introduce the working principle of Vertical Roller mills.
The work-energy principle is a general principle which can be applied specifically to rotating objects. For pure rotation, the net work is equal to the change in rotational kinetic energy: For a constant torque, the work can be expressed as. More. working principle or …
After being rolled over by the rollers, the material is conveyed to a stationary nozzle ring due to the rotation of the grinding table. Gases (air or hot gas) flow through this nozzle ring, take up the ground and dried material and convey it to the classifier where it is separated by the rotating wheel (rotor) into grits and fines.
The material is drawn in between the rollers and grinding table and ground by pressure and shear. The required pressure forces are produced by a hydropneumatic tension system. After being rolled over by the rollers, the material is conveyed to a stationary nozzle ring due to the rotation of the grinding table.

One roller is fixed, while the second roller is screwed down by means of hydraulic cylinders, in order to adjust the grinding gap, or to "relax" it for coarse particles. The hydraulic system is also responsible for balancing out one-sided loadings, i.e., the bladder accumulators increase the pressure on the more heavily loaded side.
