Factors affecting ball mill s active power and grinding efficiency 球磨机有功功率和磨矿效率影响因素研究
Under given conditions there is a correspondence between the active power and the grinding efficiency , which is one of key parameters for evaluating the grinding efficiency 在一定磨矿条件下磨机有功功率与磨矿效率有明显对应关系,而且是判断磨矿效率的重要参数之一。
Industrial application and the analysis of technological economy showed that chme steel lining board ' s producing process is simple and controllable and the duriablity of chme steel lining board is 30 percent higer than zgmnl3 lining board while the first price of chme steel lining board is little higer than zgmnl3 lining board 而技术经济分析则表明, chme钢衬板的生产成本虽然略高于2gmn13衬板,但综合考虑磨矿效率与磨耗成本后,生产每吨chme钢衬板仍可比zgmn13衬板多获利1230元,具有明显的经济与社会效益。
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 通过对球磨机球料比、介质充填率和磨矿浓度与有功功率和磨矿效率试验,分析了影响球磨机功率和磨矿效率的主要因素,建立了球磨机内部状态(球料比、介质充填率和磨矿浓度)与外部参数(有功功率、磨矿效率)之间的关系,提出了改善磨矿效率的合理操作参数。
