Test The Grindability of Your Favourite Elements - Sepro Labs

Test The Grindability of Your Favourite Elements. A grindability test is a procedure that evaluates the resistance of a material to ball milling. This test is an effective way to calculate and compare the Bond Work Index (BW¡) of different ores. The higher the Bond Work Index, the more difficult it is to grind the material.

Determination of the Bond work index of binary mixtures by ...

Apparatus and methods. Traditional Bond ball mill (Ø305 × 305 mm) and Hardgrove mill were used for the measurements. The traditional Hardgrove Grindability Index (HGI) was determined by using the following equation: (3) HGI = 13 + 6.93 m P where m P means the mass of product particles finer 75 μm in grams.
