Ball mill and rod mill are suitable for different materials 1. Selection by material's hardness Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2. Selection by required particle size
Ball mill, as an indispensable grinding equipment in mineral processing, brings economic benefits to the separation plant.Ball mill is mainly used for grinding materials in the industrial production process. Because of the large volume and tonnage weight of the ball mill, the noise in the production process is relatively large, and the noise is generally above 95dB (A), which can exceed 1MdB ...
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
Nov 12, 2015· The method is used to size a cement ball mill. Efficiency correction factors are applied with the Bond equation. The method is valid both for clinker grinding and for raw materials grinding. This method only gives a rough and initial idea for sizing a cement ball mill.

Industrial uses – raw material for cement production, filler in paper making, industrial coatings and ... Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill .
The established technique for determining power requirements for ball mills is the Bond method (Bond, 1961). This method also involves the application of some 'efficiency factors' as described by Rowland (1975). Bond's equation describes the specific power required to reduce a feed from a specified feed F80 to a product with a specified P80:
Ball Mill Design/Power Calculation. The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and ...
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
