The Way to Improve Grinding Efficiency of Ball Mill

There are many factors influencing the grinding efficiency of ball mill.When processing one mineral, the influencing factors of grinding efficiency include property of grinding media, matching of grinding media, filling ratio of grinding media, ratio of grinding balls to materials, grinding density and feeding granularity.It is very difficult to precisely and scientifically calculate the influence relation of every factor. However, there is one influencing factor which is the most direct, clear and most efficient, feeding granularity.

When the grinding plant, grinding balls and grinding density are the same, the grinding efficiency is mainly related to feeding granularity. Grinding mills are used for processing large materials to products with the required granularity, so that if the granularity of feeding materials is similar to that of required, the working load of grinding mills will be smaller and the working efficiency will be higher.


According to our calculation, when reducing the feeding granularity from 20mm to 5mm, the relative productivity of grinding mills will be improved by about 30%, which means that the ball grinding mill can process 30% more ores in unit time. When such cost as energy consumption and personnel is certain, if 30% more concentrate products can be got in ore beneficiation plant, the increase in economic benefits for the ore beneficiation plant will be huge, for this reason, reducing the feeding granularity is the most efficiency way of improving the grinding efficiency of ball mill.
