This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.

The Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a non-additive behavior. The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant .
3.1 This test method is used to determine if a freshly mixed refractory castable is of the proper consistency to provide optimum performance. There are times when the manufacturer's specified water content and consistency will purposely not lead to the correct ball in hand but should be used to provide optimum performance.
A ball mill is a type of grinder or mill used to mill the materials into fine powder in pharmaceutical industry, It was found that this method termed mechanical alloying could successfully produce fine, uniform dispersions of oxide particles in nickel-base super, Ball Mill is widely used in metal and nonmetal mines, building materials and ...
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
Therefore, a fast grindability test method that uses less sample material than the Bond test is required. In this thesis, a new laboratory test method is developed. The aim of this test method is to use the Outotec Mergan mill for the grindability test, and scale the results to the Bond ball mill test. The
