Bond Work Index FormulaEquation
In the standard AC closed circuit ball mill grindability test the work index is found from. where Pi is the opening in microns of the sieve mesh tested and Gbp is the net grams of mesh undersize produced per revolution of the 12 x 12 test ball mill. The closed circuit 80 passing size P averages P1/log 20 for all sizes larger than 150 mesh.
F.C. BOND BICO BALL MILL
This Ball Mill can be used continuously or it can be used for any number of revolutions according to the type of grind desired. For instance the Fred C. Bond Grindability Tests were made in the Bico Mill running at 70 revolutions per minute with a charge of 285 iron balls ranging in size from 3/4 inch to 11/2 inch in diameter and weighing
Bond Work Index Procedure and Method
Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done: Add about 500 g of silica sand into the mill containing the ball charge. Seal the mill. Rotate for 20 revolutions to clean. Empty the mill charge and sand into the ball try once grinding is complete. Clean out the mill using a brush. Put the lid on the mill.
Bond Work Index Energy equation Grinding and Classifi ion
You need a twostage solution first stage opencircuit mill and then second stage closedcircuit mill. First stage will be broken into two parts as well you use a Bond rod mill work index for the coarse component of the ore 2.1 mm and the Bond ball mill work index for the fine component 2.1 mm .

FC Bond Ball Test Mill Sepor Inc
The FC Bond Mill was designed by F. C. Bond for use in determining the Bond Ball Mill Index a measure of grindability and power required to mill various ores. FC Bond Mills are used in laboratories throughout the world. A copy of Fred C. Bonds Method of Crushing and Grinding for determination of the Bond Index is included with each mill.
FC Bond Mill Sepor
Actual FC Bond Mill Charge Weight versus the FC Bond Weight as prescribed by Fred Bond Theory Meets Manufacturing Reality 1. Due to the varying tolerance in manufacturing of grinding balls a fraction of an inch in diameter variance on a grinding ball will make a difference on the total weight of the grinding charge.
