YuFeng introduction Ball Mill deformation causes and preventive measures

Article source：

Ball mill grinding system is an important equipment, long-term use is bound to be some problems, such as barrel distortion. If you can not handle the production

yield will have some impact. So to find a solution in time causes problems, in order to avoid this happening again, in the course you want to take precautions. Mill

shell deformation for two main reasons: one, the mill stopped for a long operation, the grinding media and part of the material is not timely unloading, the weight of

the cylinder itself, grinding and material weight together, causing cylinder deformation . 2, stop grinding mill is operating, the cylinder temperature (temperature of

the mill by IMPACT) is relatively high, in the natural cooling process, the discontinuity caused by the cylinder barrel distortion. Mill shell deformation approach 1,

troubleshooting methods. 1) to mark the lowermost part of the cylinder (available chalk). 2) The cylinder flip 180 °. 3) try to pass hot air inside the cylinder. If you do

not have the conditions, you can place several mill shell bottom stove, baking cylinder (note that when the stove is not in the baking Egypt near bush, fire can not

pounced cylinder and distance appropriate). 4) every 30min, the mill running half circle until visual mill shell restored to normal. 5) the withdrawal of cylinder heating

device for grinding lined plate and the screw connection of parts inspection, repair, cylinder deformation caused due to joint failure. Mill shell deformation failure

prevention measures 1, the mill is stopped for some reason when working in more than 30min Alley downtime should stop grinding mill operation after every 30min

to a half circle, stopping opposite the original position until the mill cylinder cool completely so far. 2, the mill intends to stop bullying long, should the mill grinding

media and materials, all poured out (clearance). Then the method described above operations until the mill shell cool completely so far. Please indicate Henan YuFeng
