How to design a Ball Mill

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.

ROM ball mill design

A side by side study: RoM ball and AG mill with F80 around 50 mm and a mill product P80 of around 250um, indicated the OWI is also considerably higher, and although it is known to be biased against finer products, the difference is sufficiently large to indicate that the RoM ball mill is less efficient than AG milling.

Grinding Media in Ball Mills for Mineral Processing

Autogenous and semi-autogenous mills are used in primary grinding whilst rod and ball mills are used in secondary grinding, with the ball mills being the most commonly used. The ball mills are either used in a dry-milling or wet-milling set-up depending on the needs of the industry in which they are utilised.

Ball Mills

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for …

Ball Mill Circuit Classification System Efficiency

A simple method for estimating the relative coarse solids inventory in the ball mill has been selected. It is the average of the coarse fraction in the ball mill feed and discharge size distributions. In closed circuit grinding, the shift in these size distributions is normally quite small.

the rotating charge inside most industrial ball mills. Most industrial ball mills have lifters. Data from 40 ball mills show that the average critical speed is 0.73 (Morrell, 1996). Research in mill charge motion (eg. Mishra and Rajamani, 1992; Inoue and Okaya, 1994) reveals how the charge motion vary with mill speed and liner/lifter profile.
