DetailsBall mills are commonly used for crushing and grinding the materials into an extremely fine form the ball mill contains a hollow cylindrical shell that rotates about its axis this cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it
DetailsIf it has been previously established that there is a reliable linear relationship between mill load and filling then two well separated points will suffice a critical parameter in the load filling relationship and in modelling a mills performance is the ball load and this should be established through grindout
DetailsSep 07 2011 re vrm and ball mill circulating load mainly in usa the term circulating load is more often used than the circulation ating load is percentage of coarse return in relation to fines it can be calculated by coarse return tph x 100 mill output range of cirulating load in a conventional close circuit ball mill is around 100200
DetailsWe have circulating load of a ball millwhy have a large circulation load if a product all finer than a certain critical size is required the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier fig 70
