【摘要】:圆锥破碎机在破碎粉磨工业中被广泛的使用,直接影响着冶金、电力、化工、建材等工业部门的生产过程。压缩比是影响破碎产品质量至关重要的参数之一,通过研究发现,在对破碎机破碎腔腔形的设计中,通常不去考虑主轴转速与物料运动的关系,导致压缩比损失的现象,进而影响了产品的质量,造成了不必要的能量损失。所以对腔形进行深入研究对节约能源、提高产品质量有重要意义。深入研究了层压破碎理论,在对腔形设计中,引入分层破碎理论,结合物料运动形式,提出一种新的腔形设计方法。分析物料的运动模型,提出破碎机生产率计算公式。在对腔形进行设计中,利用Matlab进行编程计算,绘制三种不同破碎型号的腔型曲线,分别为粗碎型、中粗碎型、细碎型。在腔形的设计中,通过将腔形参数与主轴转动相互搭配,最大限度的解决压缩比损失现象,提高破碎效率。通过对物料的压缩实验,模拟物料破碎过程。通过分析实验结果,拟合出选择函数和破碎函数。利用整体平衡原理,完成对三种不同腔型曲线产品粒度的预测,并做出分析。证明这种新的设计方法对于提高破碎产品质量具有一定的可行性,对实际生产和今后研究具有指导作用。
[Abstract]:Cone crusher is widely used in grinding industry, which directly affects the production process of metallurgical, electric power, chemical, building materials and other industrial sectors. Compression ratio is one of the most important parameters affecting the quality of crushing products. It is found that in the design of crusher cavity shape, the relationship between spindle speed and material movement is not considered, which leads to the loss of compression ratio. In turn, the quality of the product is affected, resulting in unnecessary energy loss. So it is important to study the cavity shape to save energy and improve product quality. In this paper, the laminated crushing theory is deeply studied. In the design of cavity shape, a new method of cavity shape design is proposed by introducing the theory of layered crushing and combining with the material movement form. The movement model of material is analyzed and the formula for calculating the productivity of crusher is put forward. In the design of cavity shape, Matlab is used to program and calculate, and three kinds of cavity curves of different broken models are drawn, which are coarse broken, medium coarse and fine broken. In the design of cavity shape, by matching the parameters of cavity shape with the rotation of spindle, the loss of compression ratio is solved to the maximum extent, and the crushing efficiency is improved. The process of material breaking is simulated by compressing experiment. By analyzing the experimental results, the selection function and the fragmentation function are fitted. The particle size prediction and analysis of three different cavity curve products are made by using the whole balance principle. It is proved that this new design method is feasible for improving the quality of broken products and can be used as a guide for practical production and future research.
