Through the analysis of the forces inside the cement ball mill grinding medium
and material between the trajectory, combined with the principle of ball
mill feeding device can be found that the root cause of this phenomenon is:
1, in the feed way, material is first into the innermost of the trajectory-the weak
of the grinding ability, 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 p
oor 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.
