The grinding process in ball mills (where grinding balls are used as grinding medium) is one of the widely used methods in practice to reduce the size of material particles. There are quite a lot of works devoted to the detailed consideration of interaction process of the grinding balls with the particles of the material. At the same time, the number of works on the calculation of the optimal ...

Abstract Ball drum mills (BDM) are one of the main types of coalgrinding equipment in Russia. A significant drawback of BDM is high power consumption (a significant part of the TPP's own needs). With a huge scale of production, reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and ...

The filling degree is defined as the volume of the grinding media (balls) as a percentage of the total mill volume. Since mill speed, liner shape and mill diameter are usually unchangeable parameters, the only adjustment in a mill can be made with filling level and ball size 3 shows the movement of balls as a function of ...
