摘要
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.
On the basis of analyzing the structure and abrasion of a traditional gyratory crusher＇s chamber profile, its crushing capacity was defined by computing the flux ratio of every section along the chamber height. The chamber profile was geometrically de- scribed by means of a thrice spline curve. The chamber profile target function was built with productivity and nip angle as constraint conditions, then the gyratory crusher＇s chamber profile was designed and its curves were protracted. A test scheme was set down to meet the aluminum ore crushing demand. After the crushing test of aluminum ore with the optimized chamber profile and new linings, it is shown that the crushing capacity, the certified ratio of crushing products and the working life of linings are better than those with the traditional chamber profile.
