Introduction Ball mill is an efficient tool for grinding many materials into fine powder.
May 22, 2019 The larger the ball to material ratio, the higher the grinding efficiency. But too high a ball ratio is unhelpful. Because the amount of charge is reduced when the filling factor is constant, it is bound to reduce the productivity of the set, and sometimes reduce the alloy properties Figure 8-2. The ball ratio is usually selected from 21 to 51.
Oct 23, 2020 03 3.Keeping the suitable steel ball filling ratio. Under certain rotating speed, the larger steel ball filling ratio is, the more hits of materials and the larger grinding area is. So, the energy consumption is also large. It easily leads to the change of steel ball motion state, which reversely reduces the hit effect of large particle material.

The invention concerns a method which consists in establishing, by modeling, an algorithm which defines a relationship between the filling ratio of a ball mill and the angular positions of the bottom and the top of the mill content as well as of its absorbed power, in measuring, in the mill whereof the filling rate is to be determined, the angular positions of the bottom and the top of the ...
The LD ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15, 20 and 25.
The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 3035 of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.
Jun 26, 2021 Grinding powders in a ball mill is a complex operation in which many parameters, such as geometrical factors , filling ratios , powder properties or the energy transferred to the vessel can influence the characteristics of the resulting powder.
