A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
Mar 08, 2013· calculation of ball mill grinding efficiency. dear experts . please tell me how to calculate the grinding efficiency of a closed ckt & open ckt ball mill. in literatures it is written that the grinding efficiency of ball mill is very less [less than 10%]. please expalin in a n excel sheet to calcualte the same. thanks. sidhant. reply
What are the dimensions of the ball mill you are looking at? 40% ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points.
Reliable, planetary gear unit for ball mills – with peak efficiency. ... During maintenance, the low speed ZCF coupling remains in place between the gear unit and the ball mill, while the dismounted high speed ZEXF coupling provides enough axial space to disassemble the gear unit without moving the main motor.
Earlier work by Fuerstenau and Kapur on the comminution of quartz in a single-particle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22%. Thus, as a mechanical device for producing fine particles, the ball mill is reasonably efficient energetically.

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. In this paper, 10 methods to improve efficiency are summarized.
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 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.
