摘要/Abstract

摘要： 现有旋回破碎机生产率理论模型与实际生产数据存在明显偏差,限制了新规格设备的开发设计与优化应用。针对该问题,以Metso公司60-110E型破碎机为研究对象,从堵塞层特点出发,分析物料在破碎腔中以不同下落方式运动时的速度分布与区域特征,构建了考虑上拱区与下落区物料运动规律的生产率预测模型。在此基础上, 利用SOLIDWORKS与EDEM建立破碎机三维仿真模型,结合矿石物性试验参数对颗粒模型进行修正,模拟破碎过程并获得预测生产率。同时采集现场运行数据,开展理论预测、仿真分析与实测结果的对比验证。研究结果表明:在动锥底角82.41°、进动角0.342°、开边排料尺寸160 mm条件下,动锥摆速100~600 r/min区间内理论计算与仿真趋势基本一致,均表现为生产率随摆速先增大后减小,当摆速过高时生产率趋近于零。在130 r/min工况下,理论值与实测值的相对误差为6.58%,仿真结果与实测值误差为2.98%,均在10%以内,验证了模型的准确性。该理论模型能够较好地描述旋回破碎机生产率的变化规律,为设备设计优化与性能提升提供了理论支持,具有一定的工程应用价值。

Abstract: There is a significant deviation between the existing theoretical model of gyratory crusher productivity and the actual production data,which limits the development,design and optimization application of new specifications of equipment. Aiming at this problem,the 60-110 E crusher of Metso Company is taken as the research object.Based on the characteristics of the blocking layer,the velocity distribution and regional characteristics of the material moving in different falling modes in the crushing chamber are analyzed,and the productivity prediction model considering the material movement law in the upwarp are a and the falling area is constructed.On this basis,the three-dimensional simulation model of the crusher is established by u sing SOLIDWORKS and EDEM,and the particle model is modified by combining the ore physical property test parameters to simulate the crushing process and obtain the predicted productivity.At the same time,the field operation data are collected to carry out the comparison and verification of theoretical prediction,simulation analysis and measured results.The results show that under the conditions of the bottom angle of the moving cone of 82.41°,the precession angle of 0.342° and the opening size of 160 mm,the theoretical calculation and simulation trends are basically the same in the swing speed range of 100~600 r/min.The productivity increases first and then decreases with the swing speed,and the productivity tends to zero when the swing speed is too high.Under the condition of 130 r/min,the relative error between the theoretical value and the measured value is 6.58%,and the error between the simulation result and the measured value is 2.98%,both within 10%,which verifies the accuracy of the model.The theoretical model can better describe the change law of gyratory crusher productivity,and pro vide theoretical support for equipment design optimization and performance improvement,which has certain engineering applicationvalue.
