Added water amount, grinding ball, raw material, electric current, dispersing agent, reduction gear influence the working efficiency of ball mill greatly. So we shall improve the efficiency of ball mill .

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.

Dec 26, 2017· Several factors affect the efficiency of a ball mill for cement grinding. In this article, we shall be looking at some of these factors that have been proven to influence grinding efficiency: Mill Geometry And Speed According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the [.]

The grinding efficiency of ball mill is low, the treatment capacity is low, the production energy consumption is high, the product fineness is unstable and so on, which are the problems that most concentrators will encounter. How to effectively improve the grinding efficiency of ball mill is an important problem.

For many decades the twocompartment ball mill in closed circuit with a highefficiency separator has been the mill of choice. In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely ...

Cylindrical Ball Mills. ... Here, as the size of the balls progressively decreases, there is a corresponding increase in the area of grinding surface per unit of ball charge volume and so in the efficiency of grinding, and the particles, passing through the cone from smaller to smaller balls, receive successively lighter and lighter blows, with ...

The ball mill''s low grinding efficiency, low processing capacity, high production energy consumption, and unstable product fineness are problems that most concentrators will encounter. How to effectively improve the grinding efficiency of the ball mill is an important issue. This article summarizes 10 ways to improve grinding efficiency.

The major factors discussed were: (1) As mill diameters increase critical speed specified in rpm decreases. (Bond, 1960). This is an inverse relationship of the square root of the mill Increases in grinding efficiency with increasing ball mill diameters makes. Factors Affecting Ball Mill Grinding Efficiency 911 Metallurgist
