In many grinding plants mills which have metallic or rubber liners suffer from bolt breakage. Our technicians come across broken mill bolts at many sites around the world, to the operators of the mills it is an almost normal occurrence, but if you have breaking bolts there is an underlying problem which needs to be fixed.

TowerMill is a vertical agitated media mill developed in Japan in the 1950s. Until now, TowerMills have been used in ferrous and non-ferrous mines for processes of ore grinding, flue gas desulfurization (FGD), limestone grinding for neutralization and futher in other industries such as environmental fields all over the world, for the advantageous capability of high capacity and fine grinding.

There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade. Ball mills working as the secondary portion of a grinding circuit will utilize the ...

The two main functions of a mill liner consist in protecting the mill shell against wear and in transmitting the energy of the mill motor to the grinding charge to carry out the required size reduction in the most efficient way. For a mill liner, the design as well as the liner material are to be considered. The required movement of the mill charge to carry out effi-
