estimating the required energy for milling (Levin, 1989) and mill scaling-up (Man, 2002). Kinetic grinding test approach to estimate the ball mill work index 343 The W i parameter is obtained from Bond's ball mill grindability test (Bond, 1961).
The laboratory test work program was carried out on SAG belt cut and geo-unit samples of two BC copper-porphyry orebodies yielding an exponent of -0.56 across the range of typical ball mill particle size targets. For validation, the equation was run against African data by Levin (1989)

levin test on ball mill_Levin Grindability Index Test Method & ProcedureThe requirement of 2030 kg may be a prohibitive factor. The Levin test is a modified Bond Ball test.
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.
The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...
Laboratory Ball Mills; Ball Mills use grinding media in spherical or cylindrical shapes in rotating containers to grind a wide range of material types to very fine sizes. Jars and grinding media are available in a wide variety of material types to optimize performance characteristics for long-term wear-resistance, low contamination levels, or ...
The Ball Mill Abrasion (BMA) test was developed by the University of Queensland Materials Performance group to simulate the high stress abrasion conditions experienced in production ball mills.
