internal feed
1.Inspect internal-build spare parts quality and feed back the problem to tool shop.
4.According to the tests on ball-feed ratio, medium filling percent age, ground pulp density, active power and grinding efficiency, the authors anal yse main factors affecting ball mill′s active power and grinding efficiency, es tablishing the relationship between ball mill′s internal state (such as ball-f eed ratia, medium filling percentage and ground pulp density) and external param eters (such as active power and grinding efficiency) and giving appropriate oper ating parameters for improving grinding efficiency.
