Units are kWh/t based on Morrell's empirical calibration. This value is used in the Morrell Mi models. Levin B parameter is calculated for a sample if the following are available: umClosing, F80, P80, gpr, fdpassing. Units of the Levin B are mWh per revolution of a standard Bond grindability ball mill …
Here is the old Allis-Chalmers Bond Work Index Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. It is screen analyzed and packed by shaking in a 1000-cc graduated cylinder, and the weight of 700 cc is placed in the mill and ground dry at 250 per cent circulating load. The mill is 12 in. x 12 ...

Grinding is a process of reduction of lumps to powder depending on the requirement of particle size and particle shape. The present investigation involves the identify the physical properties of three different types of iron ores by using Bond ball mill. The result shows that the maximum Bond work index of 14 KWh/mt was obtained for `A' type iron ore sample.
A laboratory size ball mill was used with ball media of sizes 10 m. . It is however widely determined that ball mills have very low efficiencies in terms of . of industries such as the minerals processing, metallurgy, mining, chemicals, . material dependent and thus depended on the grindability or hardness of the sample ore.
mills. 2.1 Terms Associaed with Ball Mill Operation 2.1.1 Grindability (G): Grindability is the number of net grams of screen undersized product per revolution [1]. The chief purpose of study of the grindability is to evaluate the size and type of mill needed to produce a specified tonnage and the power requirement for grinding. Detailed ...
Bond Grindability Test Procedure. The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured.
