· Once the grindability and floatability indices are calculated individually, the following index will be proposed to evaluate the performance of the regrinding mill in the mineral processing plants: (3) I = A + D 2 where A and D denote the values obtained from Steps 1 and 2, respectively. This index usually varies between −1 and +1. From a theoretical point of view, it is possible that

Determining the Bond work index is a standardized method for characterizing the comminution performance of mineral samples. CEMTEC uses this method for designing rod and ball mills. The comminution performance is, just like the desired comminution step and the production capacity, crucial for determining the required mill size. The necessary minimum sample quantity is 15 kg. The test .
based on square root of two (√2). This was followed by grinding under the same parameters of mill size, grinding media, mill charge and tumbling time at 1425 rpm and final sieving. Using Gaudin Schumann relation for the determination of 80% feed and products of the reference and test ores; the grindability was determined from the
Terms Associaed with Ball Mill Operation 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 prediction of grinding rate and product size distribution from ...
