Select the required three Raymond mill rolls

Grinding roller is the main component Raymond. In production will be able to achieve the effect of grinding, development of raymond mill need to bear greater radial pressure of work. At the same time also with the roller surface friction material have a strong effect. Need roller has the following requirements; 1) require roller should have a certain toughness, wear resistance and good thermal conductivity. 2) require the roller surface is not trachoma, porosity, hardness varies or manufacturing defects such as cracks. 3) In order to achieve smooth operation and maintenance of rolling distance between two roller, cylindrical roller should maintain accurate, flat surface, its runout should be less than 0.05 mm, no axial straightness of less than 0.01 mm, roller concentricity deviation at both ends of the minor axis is not greater than 0.02 mm.
