The feeder (A) introduces raw material into the grinding chamber in the base of the Roller Mill (B) at a rate determined by pressure variations with the grinding mill. Plows located ahead of each roller direct the material upward and between the grinding rolls and the heavy alloy steel bull ring where it is ground to size.
A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls. These backup rolls are larger and contact the back side of the smaller rolls.

The invention relates to a method of producing a grinding roll in which a roll tire made from a highly wear-resistant bainitic cast material is applied to the basic roll body. In order to create a roll tire with particularly high reliability against fractures and with relatively high wear resistance and compression strength, the roll tire is produced from a ductile bainitic spheroidal graphite ...
Custom roll grinding and finishing services. Capabilities include crush roll, diamond roll and CNC profile grinding.

While uncommon in roll grinding, semi-synthetic fluids are a combination of synthetic and soluble oil fluids. Most coolant also contains biocides, surfactants, extreme pressure agents, anti-oxidants and corrosion inhibitors. Selecting the optimum coolant for an application depends on the roll material ground and the grinding wheel specification.
Three stationary grinding rollers roll on a rotating grinding table. 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 rolls themselves rotate at a constant speed, hence at some point in the roll zone the surface velocity of the rolls and that of the material are exactly the same. This is point is known as the no slip point. Before this point the rolls are moving faster than the material, after this point the material is moving faster than the rolls.
