steel ball High hardness is not good for grinding
When choosing a steel ball, two problems are often overlooked: the steel ball is not as solid as possible, but has its proper hardness value; the steel ball density is also a problem that can not be ignored. Generally speaking, with the increase of hardness, as long as no crushing occurs, the unit load of steel ball will decrease; moreover, the deformation of the sphere will be small, the deformation of the sphere will be small during the crushing, and the energy can be more used to crush the mineral particles. Mill productivity can be increased. However, the increase of steel ball hardness can only be modest, there is an appropriate range, not the harder the better.
If you consider only the ball consumption, the higher the hardness lower consumption. However, for mill productivity, the productivity increases with the increase of steel ball hardness within a certain range, but when the hardness exceeds a certain range, it adversely affects the mill productivity and reduces the mill productivity. steel ball When the hardness is too high, there are two reasons for the disadvantage of grinding:
①steel ball rebound bounce serious, causing some of the energy loss in the rebound, so the steel ball energy is not used more for crushing, thus affecting the crushing;
②steel ball When the hardness is too high, the ball and the ball contact each other when sliding, can not effectively kerchief live ball between the ball, so that the grinding effect of mineral particles weakened.
As for the effect of steel ball density on grinding, in general, the same size ball has a large productivity and a low density has a low productivity.
