Description

Technical Field

[0001] The utility model relates to the technical field of ball mill assembly, in particular to an easy-to-install ball mill slurry lifter. Background Art

[0002] At present, most ball mills are overflow type. The hollow shaft diameter at the discharge end of the overflow ball mill is slightly larger than the hollow shaft diameter at the feed end. When the internal slurry surface height is higher than the lower busbar of the discharge port, the slurry overflows from the discharge port and is discharged from the ball mill.

[0003] Overflow ball mills have sufficient grinding and good grinding effect. However, the discharge efficiency is too low, and the over-grinding of minerals brings inconvenience to subsequent processing, and it is not flexible and can not meet the needs of equipment use.

[0004] In order to improve the discharge efficiency of the overflow ball mill, our company customized a pulp lifter for the discharge end of the overflow ball mill, and changed the overflow ball mill to a grid ball mill. The slurry in the ball mill is actively discharged through the pulp lifter, which reduces the time the slurry stays in the ball mill, greatly improves the discharge efficiency of the ball mill, and reduces excessive wear of the minerals. However, when the customer's equipment was changed from an overflow ball mill to a grid ball mill, there were too few fixing holes in the ball mill shell that could be used to fix the pulp lifter, which made the installation of the pulp lifter difficult.
