ball mill shell Material and Installation techniques

Ball mill cylinder material with high strength, good plasticity and weld metal materials with good sex, most using ordinary steel structure, large-scale ball mill cylinder body generally made of 16 mm steel is mainly due to the fifty percent higher than the average, the elasticity of the material strength and corrosion resistant capability is strong, impact toughness are better, especially at low temperatures, the performance is more good.In terms of processing, can be used as a convenient branch cutting and cutting, welding, material fatigue resistant wear resistant property.


Because of ball mill for a long time at a high speed, barrel temperature have different equipment caused by the axial deformation, this is the effect of heat bilges cold shrink, the discharge end due to close to the transmission device, there is no any change of axial, this gear is to guarantee the normal occlusion.So, just at the feed end design can adapt to the axial with heat - structure.Two ways to adjust the axial deformation of the problem: when installed in the position of the hollow bearing neck shoulder, and set aside a certain gap between the bearing;Or in the middle of the bearing seat and floor level to install a few root steel roller, when the cylinder heated increases and changes in feeding the main bearing base can move along the steel roller.
