摘要/Abstract

摘要： 红土镍矿物料粘性大且夹杂大块矿石的原料特征导致其破碎效率不高,为了提高双齿辊破碎机对其的破碎效率,通过仿真分析研究了红土镍矿物料在双齿辊破碎机中的破碎过程。首先通过单轴压缩试验对红土镍矿物料中的矿石进行离散元参数标定,接着结合离散元方法(DEM)与Tavares破碎模型分析了破碎机齿牙数量、辊齿齿高、齿辊转速等对红土镍矿物料处理量及产品粒度分布的影响规律。结果表明:破碎机齿牙数量越多、齿高越高、齿辊转速越低,物料黏附情况越严重;齿牙数量为3、辊齿齿高为40 mm、破碎机转速为70 r/min时,红土镍矿物料的破碎处理量与粒度控制达到最佳平衡,出料粒度能够满足后续分选或冶炼的工艺要求;在破碎腔齿辊两侧加装梳齿板后, 物料处理量提升至91.5 kg,相较于无梳齿板工况增加13%,显著改善了破碎作业效果;在高粘性红土镍矿物料破碎中,辊齿形状对处理量提升作用有限。研究结果可为针对粘性物料的破碎工况提供理论和技术支撑。

Abstract: The raw material characteristics of laterite nickel ore,such as high viscosity and inclusion of large ore lumps, lead to low crushing efficiency.To improve the crushing efficiency of the double-tooth roller crusher for this ore,the crushing process of laterite nickel ore in the double-tooth roller crusher was studied through simulation analysis.First,the discrete ele ment parameters of the ore in laterite nickel ore were calibrated via uniaxial compression tests.Then,combined with the dis crete element method (DEM) and the Tavares crushing model,the influence laws of parameters such as the number of crusher teeth,tooth height of the roller teeth,and rotation speed of the roller teeth on the processing capacity of laterite nickel ore and the particle size distribution of products were analyzed.The results showed that:the more the number of crusher teeth,the high er the tooth height,and the lower the rotation speed of the roller teeth,the more serious the material adhesion.When the num ber of teeth is 3,the tooth height of the roller teeth is 40 mm,and the rotation speed of the crusher is 70 r/min,the crushing processing capacity and particle size control of laterite nickel ore reach the optimal balance,and the discharge particle size can meet the process requirements of subsequent separation or smelting.After installing comb plates on both sides of the roller teeth in the crushing chamber,the material processing capacity is increased to 91.5 kg,which is 13% higher than that without comb plates,significantly improving the crushing operation effect;In the crushing of high-viscosity laterite nickel ore,the shape of the roller teeth has a limited effect on improving the processing capacity.The research results can provide theoretical and technical support for the crushing conditions of viscous materials.
