Coke ball mill design stability test

The raw coal and petroleum coke samples were ground with a laboratory-size ball mill, and then passed through a 100 mesh sieve to obtain experimental samples. The PSD of the sample was determined using a Mastersizer 2000 (Malvern Ltd., Britain). PCLS preparation was standardized and used for all samples tested. At the outset, lignite, petroleum

    Technical Note Why is the Bond Ball Mill Grindability Test

    The Bond Ball Mill Grindability Test is a locked-cycle laboratory grinding test. It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling. This Index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill scale-up. The test has existed for more than 40 years
