Bond Work Index Procedure and Method

2020-6-25  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.

Grinding Ball Mill Power Design Calculation

We have Grinding Ball Mill Power Design Calculation,The bond work index, w i, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a given size of
