The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
balance modeling, for the identification of the optimum ball filling during quartz grinding and the scaleup of laboratory mill results to fullscale. 2. Theoretical background Let''s consider a mass of material M in a ball mill that after breakage needs to be divided, by using x i screens, into i + 1 narrow size classes. Normally, for a size ...

Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc. The applications of ball mills are ubiquitous in mineral
Although it was developed nearly 50 years ago, Bond''s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.

Ball Mill Scaleup by this method is known as collision energy based population balance appropriateness of this model is shown for 38cm ball mill. Comminution in ball mills account for a significant amount of power consumption in mineral processing plants.
A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances to simulate the mill. The energy balance relies on temperature and mass flow data. The key control parameters to be measured are mill temperature (feed and discharge streams), mill power draw and the mass flow rate in the feed stream.
