磨球外形虽简单,但却是磨机的复杂机械部件和基本元件。要想达到设计寿命和磨矿目的,磨球的物理特性和质量必须符合要求。坚硬且不易碎裂是磨球应具备的基本条件,尺寸、质量、硬度、化学组成和微观结构是磨球的重要变量。应对这些重要变量进行设计、标定、控制和检验,以获得最佳的磨矿效果。如果没有详细标定磨球的性能,或者磨球未达到期望的性能和质量要求,可能会引起磨矿生产率的下降及成本的增加,以致危及到选矿厂在激烈竞争的矿山工业中的生存。 Ball shape is simple, but it is the mill’s complex mechanical components and basic components. To achieve the design life and grinding purposes, the physical properties and quality of the balls must meet the requirements. Hard and not easy to break the ball is the basic conditions for the ball, size, quality, hardness, chemical composition and microstructure is an important variable ball mill. These important variables should be designed, calibrated, controlled and tested for optimal grinding results. Failure to detail the performance of the ball or to fail to achieve the desired performance and quality requirements may result in lower mill productivity and increased costs that threaten the viability of the concentrator in the highly competitive mining industry.
