Mar 25, 1980nbsp018332the crosssection of the grinding chamber is defined by liner plates and is generally polygonal and preferably approximately square. at the corners, the liner plates are directly supported on the inside surface of a shell which surrounds the liner. elsewhere, the liner plates are supported on the inside surface by spacers.
We specially design the material for cement mill liners ,which includes boltless liners,shell liners, grate plates ,end liners etc..the material can not only achieve ideal hardness more than hrc50 but also ideal toughness value ak30100j. the liners are more reliable and safer than normal liners,
Sectional, solid liners made of refractory concrete, pumice concrete or terracotta, sectional solid liners are only likely to be used if the existing stack is particularly large and straight, or if the stack is rebuilt, in which case they will be builtin as the stack is rebuilt.

1. liners protect the outer shell of the mill from wear liners are renewable. 2. lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge.
This signature could be effectively used to optimize the milling performance by investigating this signatures relation to mill product size, mill throughput, makeup ball size, mill speed, liner profile and ball addition rates. at the same time, it can also be used to design balls and liner systems that can survive longer in the mill.
