Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop. The stirred mills are charged with a media size of 10–12 mm and operated at a maximum tip speed of 3–8 m/s.

— 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. These mills may be divided into three types ROD MILLS, BALL MILLS and AUTOGENOUS MILLS.
This article describes the Hogg and Fuerstenau (1972) method for estimating the power draw of a tumbling mill. Model theory
The media and material are rotated to generate a tumbling action, causing the grinding media to collide with the material and break it into smaller particles. The ball mill diagram typically consists of a horizontal cylinder with a diameter and length that …

— In case you're new to hammer mills in pharmaceutical and food processing industries, here are three crucial steps that will help you understand how this equipment works. Before that, you can watch this video to see how hammer mills work: ... Place all your materials in the section labelled "1" above. Depending on the design of the hammer ...
model, simulate and validate charge behaviour in tumbling mills. These numerical models give possibilities to better understand the physical and mechanical behaviour of particulate material systems during grinding in a tumbling mill. This is important in order to develop and optimise future high-capacity grinding circuits and save energy.
— For the first approach, the power draw was calculated using a variation of the "torque arm" principle commonly used for tumbling mills in comminution literature; for example Harris and Schnock, 1985.The centre of mass was based on the previously calculated residence time fraction distribution and not necessarily equal to the mean …
IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both …

— Low speed: At low speed, the mass of balls will slide or roll up one over another and will not produce a significant amount of size reduction. High Speed: At high-speed balls are thrown to the cylinder wall due to centrifugal force and no grinding will occur. Normal speed: At Normal speed balls are carried almost to the top of the mill and …
The most common types of tumbling mills are the rod-, ball- and autogenous mills. Depending on the type of ore, there are different charge media to be used. In rod and ball mills, the different charge media are usually made of steel and added to the mill. In autogenous mills, the ore itself is used as charge medium.
