Wear prediction of multi-material time-varying chamber of cone crusher

为动态分析计算圆锥破碎机物料质量以支持产品的优化设计,利用RMT-150B岩石力学实验系统对圆锥破碎机层压破碎过程进行模拟实验,以此建立1个基于物料抗压强度、压缩比和粒度分布系数的多种物料破碎力求解模型。基于层压破碎理论和物料运动学特性,并结合物料破碎生产线的圆锥破碎机腔型磨损量,得到关于破碎腔表面磨损的时变磨损模型。采集分析破碎腔磨损的实验结果,并与时变磨损模型的求解结果进行对比分析。研究结果表明:利用所建立的时变磨损模型可以对破碎腔磨损量进行求解,其求解结果与实验结果相符,可实现生产线中对圆锥破碎机腔型表面磨损量的预测。

In order to analyze and calculate crushing quality and support for cone crusher optimization design, RMT-150 B rock mechanics test system was used to simulate the interparticle breakage process of cone crusher. A multi-material crushing model was built by experimental research based on the compressive strength, compressive ratio and size distribution index. The kinematics of rock material in the crushing chamber was analyzed by the inter-particle breakage theory. A time-varying chamber wear model was obtained by studying the chamber wear of a crushing circuit. Experimental results of chamber wear and solving results of time-varying chamber wear model were comparatively analyzed. The results show that the model can be used to solve wear cone crusher, the wear of the model is consistent with the research results, and the prediction of wear can be realized.
