Through the analysis of the ball mill grinding medium and material between the trajectory of the forces, combined with the principle of ball mill feeding device can be found that the root cause of this phenomenon is:
1, the feed way of ball mill, material is first into the trajectory of the innermost - grinding ability of the weak, only rely on the circular motion of the centrifugal force and continuously feeding material thrust in the grinding medium clearance of material to the trajectory of the outer movement, step by step in to the ground after running a certain distance, to move into the path of the outer layer, due to poor liquidity in the coarser particles in gap, less fine particle movement is fast, it is difficult to reach the trajectory of the outer layer, more concentrated in the area near the ball mill feed end a distance.
2, cross section area is the lining of the trajectory, grinding effect is small, coarse particle is not effective, so rich with a lot of coarse particles. As can be seen in the cross section in the ball mill, material is from the grinding ability of the weakest to the strongest in movement, coarse material movement to the grinding ability of the strongest hard outer layer, material distribution is not reasonable, is not conducive to give full play to the ball mill grinding.
