Grinding Mill Design & Ball Mill Manufacturer
The different types of grinding mills are based on the different types of tumbling media that can be used: steel rods (rod mills), steel balls (ball mills), and rock material (autogenous mills, pebble mills). ROD MILLS. The grinding charge in a rod mill consists of straight steel rods with an initial diameter of 50-100 mm.

Tumbling Mills | Encyclopedia
Tumbling mills have been widely implemented in many industrial sectors for the grinding of bulk materials. They have been used for decades in the production of fines and in the final stages of ore comminution, where optimal levels for the enrichment particles’ sizes are obtained. Even though these ubiquitous machines of relatively simple construction have been subjected to extensive ...

Tumbling Mill Working Capacity Influencing Factors
Tumbling mill is also known as a ball mill or rod mill. They are all composed of a cylindrical cylinder lying horizontally on the bearing, and the material is ground into powder by rotating the cylinder. When we want to discuss the factors that affect the tumbling mill working capacity, we must first know the working principle of the tumbling mill.

Grinding Mill Power - 911 Metallurgist
The power required to drive a tumbling mill is of interest both to the designer and to the mill operator: to the former as a basis of design for the determination of the necessary size of the elements of the machine; and to the latter because all other factors being equal, the most economical machine is that which demands a minimum power for driving.

DEM-PBM approach to predicting particle size distribution ...
Then, thepopidation balance model (PBM), based on impact energy distribution, was used to predict the final particle size distribution in a batch mill and compared with experimental data. It is demonstrated that the DEM-PBM approach allows a reliable solution to predict particle size distribution for tumbling mills.

Rod Mills - Mineral Processing & Metallurgy
Historically there has been three basic ways of grinding ore, hammer mills, rolls, or wet tumbling mills. Hammer mills and rolls are not used that often and then usually only for special applications as in lab work or chemical preparation. The type of mill that is used for grinding ore in a modern concentrator is the wet tumbling mill.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

The next step is power prediction by the discrete element method–based tumbling mill simulations. Since the density of grinding balls and ore particles is considered in this method, it is equally applicable to ball mills as well as SAG mills. The two-dimensional DEM code is easy to use, and it does not require extra computational resources.
