Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).
Ball breakage contaminates the ground material and can damage the mill. Particularly at risk are the grinding body separation devices such as separation gaps, sieve gaps and sieve cartridges as well as the mechanical seal. Ceramic balls in the diameter range up to 3.5 mm can be produced in large quantities by means of spray and droplet processes.
Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

Furthermore, it is worth mentioning that the application of ceramic balls in tumbling mill is exceedingly economic, given that the power consumption of the tumbling mill has been reduced by 38.5%, and the wear consumption of the grinding media by 60%. ... A family of possible methods to the resolution of this calculation is the iterative ...
This study explored the breakage kinetics of cement clinker in a lab-scale ball mill loaded with steel or alumina balls of 20, 30, and 40 mm sizes and their mixtures. The temporal evolution of the particle size distribution (PSD) was measured by sieving and laser diffraction. A global optimizer-based back-calculation method, based on a population …
The grinding ceramic ball mill uses different ball mill ceramic liner types according to production needs to meet different needs. The finess of ceramic ball mills depend on the grinding time. The electro-hydraulic machine is auto-coupled and decompressed to reduce the starting current. Its structure is divided into integral and independent.
The grinding efficiency of a ball mill is determined by the product size distribution, energy consumption, and the grinding costs. According to Hassanzadeh [ 6 …
