在分析当前旋回破碎腔型结构及衬板磨损特征的基础上,通过计算破碎腔各截面通过率确定破碎产能,采用三次样条曲线对破碎腔型进行几何描述.以破碎生产率和啮角为约束条件建立破碎腔的目标函数,对旋回破碎腔进行优化设计,利用计算机绘制腔型曲线.按照高铝矿的破碎实际要求制定了实验方案.实验结果表明,采用优化后腔型和新衬板,其破碎产能、破碎产品的合格率和衬板耐磨寿命均有显著提高.
Based on the analysis of the wear characteristics of the current gyratory crushing cavity structure and lining, the crushing capacity was determined by calculating the passing rate of each section of the crushing cavity, and the cubic spline curve was used to describe the crushing cavity geometry.Restricted by the crushing productivity and the nip angle The objective function of the crushing chamber is established, the optimum design of the crushing chamber is made, and the cavity curve is drawn by the computer.The experimental scheme is set up according to the actual requirement of crushing the high-aluminum ore.The experimental results show that the optimized chamber, Its crushing capacity, crushing products and liner wear rate of life have significantly improved.
