During the operation of the ball mill, due to many factors, there will be many failures. If it is not resolved in time, it will directly cause the production to be difficult to proceed smoothly. According to different failure phenomena, analyze the reasons and adopt correct and reasonable solutions to ensure the normal performance of the ball mill.
Ball mill liners is installed inside the ball mill, which has the function of protecting the cylinder body and adjusting the movement trajectory of the medium. In the process of grinding, the ball mill liners are subjected to great impact load, and its own wear is serious, the fracture or wear failure often occurs, which seriously affects the ...
Valley Forge has recently developed a liner bolt innovation to improve the reliability of mill liners and liner bolts in ore grinding mill applications. Recently, concern has been raised about liner breakages triggered by stress concentrations found at the base of the liner pocket where contact is typically made with the bolt head.

Failure Analysis of Ball Mill Liner-Goldpro-First, the main function of the ball mill liner is to protect the mill barrel and drive the grinding ball inside the grinding to do the sloping movement to smash the material in the crushing mill. To this end, the mill liner is required to have sufficient lifting and disturbing ability for the grinding ball.
The ball mill liner is lined in the cylinder of the ball mill. The function is to protect the inner wall of the cylinder from being damaged by the impact of materials and steel balls. At the same time, different liner shapes can be used to adjust the motion state of the grinding medium in the cylinder to help Grinding media can grind materials ...
In these days because of larger face angels, overthrowing steel balls may not be the common reason for liner breakage but poor operation and casting issues can cause more damages and by poor operation I meant low charge level and low solid concentration in SAG mills. Jean Rasczak 6 years ago Like I'd put liner failure to one of two causes.
When the ball mill liners and grinding media material being greater impact chiseling liners, grinding or smashing hit when falling rolling, cutting corners lining material, when liner strength could not withstand the impact generated by chiseling High stress fracture. This is a non-normal failure, in the manufacturing and use should be prevented.
Secondly, it is necessary to ensure that the ball mill has a good power supply and the bearing motor is driven normally to avoid sudden power failure or shutdown failure. Finally, whether it is dry grinding or wet grinding, the normal operation of the dust removal system and the water supply system should be ensured.
