XMGQΦ305 Grinding Bond Ball (Rod) Mill is mainly applied for testing the grinding work index of the material of every kinds of ores, slag, etc. Under the specific rotation speed for dry grinding, then screening the products, weighing, repeat operation several times,Comparative study of SPEX and planetary milling . · that the higher milling speed in the SPEX milling method leads to a higher milling energy and consequently lower particle size. For the same milling time of 2 h, the particle size decreases down to nano-scale using a SPEX ball mill whereas the planetary ball mill products contained a varied size in the range of micron and submicron regimes.[PDF] Why is the Bond Ball Mill Grindability Test done theThe 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.Ball MillingBall milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force.
