The Ball Mill’s working efficiency directly affects the concentrator economic benefits of the Beneficiationfactories Therefore improve the efficiency of the mill is very importantGenerally speaking, the factors restricting the improvement of the ball mill efficiency as following:1 The electric currentFor ball mill, enlarging the current is to increase the rotate

Due to the high energy demand and the inherently lowenergy efficiency of conventional ball mill grinding, the cement industry is continually searchingfor new ways to reduce the energy use by improvements in mill design and circuit configurationIn recent years, the use of alternative fuels has already increased significantly, however thepotential for further improvements still exists

Enhance the barrel volume can improve the ball mill working efficiency Ordinary alloy liner plate has thick thickness and large weight, which reduces the ball mill volume and increase the power consumption, lower the working efficiency Therefore, the liner plate quality is very important, ZGMn13 liner plate is the suitable choice This plate is wearable with suitable thickness, the surface

parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change • Population balance modelling was deemed unsuitable for this purpose As noted by Meloy et al, (1990), any number of different

Due to the high energy demand and the inherently lowenergy efficiency of conventional ball mill grinding, the cement industry is continually searchingfor new ways to reduce the energy use by improvements in mill design and circuit configurationIn recent years, the use of alternative fuels has already increased significantly, however thepotential for further improvements still exists In

Ball mills are usually the largest consumers of energy within a mineral concentrator Comminution is responsible for 50% of the total mineral processing cost In today’s global markets, expanding mining groups are trying to optimize mill performances Since comminution is concerned with liberating valuable minerals for recovery in the separation process, it is crucial to run the mills at the

Both mills are driven by 4500 HP motorsIn 2007, several comminution circuit studies were performed to assess circuit performance and map a course for improvement This paper discusses the results of those studies including an analysis of minetomill opportunities, grinding work index efficiency, and ball mill functional performance Subsequently, improvements to the circuit were made to

One of these, "Circuit Classification System Efficiency" (CSE), is the fraction of "coarse" material inside the ball mill upon which grinding energy is deliberately expended, versus the remaining
