Ball Mill Design Pdf
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 you are designing for. Use this online calculators for and as well as. In extracting from I will also provide 2 Ball Mill Sizing (Design) example done ‘by-hand’ from tables and charts.
Today, much of this mill designing is done by computers, and others. These are a good back-to-basics exercises for those wanting to understand what is behind or inside the machines.
Example Calculation A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power. The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is calculated from known tables ‘the old fashion way’.
Here is a section of a mill in operation. The power input required to maintain this condition is theoretically: The value of the angle “ a” varies with the type of discharge, percent of critical speed, and grinding condition. In order to use the preceding equation, it is necessary to have considerable data on existing installations.
Continuous Ball Mill Design
Therefore, this approach has been simplified as follows: Five basics conditions determine the horsepower drawn by a mill:. Diameter. Length.% Loading. Speed. Mill type These conditions have been built into factors which are given in the figure above.
