Talk with the Experts at Paul O Abbe about your process requirements and Ball Mill the ball charge for to the Ball Mills and Ceramic Lined Mills
This paper focuses on the use of a numerical tool known as the discrete element method DEM to study the motion of ball charge in ball mills DEM is employed to simulate the motion of individual balls While doing so the effect of liner design on the grinding performance of the mill is studied Two important factors such as the configuration of the liner and the geometry of the lifting

Optimization Of Ball Mill Inlet ball mill charge foster wheeler ball mill ball charge
The energy efficiency of tumbling mills can be examined by directly looking at the motion of rocks and steel balls inside the mill The make up of the charge and the lifter bars attached to the inside of the mill shell can be designed particularly to maximize the mass of ore fractured per unit of energy spent on the mill
Mill liners need to protect the mill shell from damages due to wear and transmit the energy from the rotating mill to the ball charge The rules that guide the design of a liner depend on the grinding mechanisms required for the specific mill
