CONTROLLED VIBRATING MILL FOR GRINDING BULK MEDIUM

Abstract

One of the advanced types of grinding equipment are vibrating mills, which provide high specific productivity at relatively low energy consumption, adjustable tone of grinding products. Vibration impact on the product significantly increases the shock-absorbing effect with the possibility of wide and separate variation of shock and abrasion factors. Significant speed of mechanical and heat and mass transfer processes, a high degree of homogeneity of the obtained products, the possibility of efficient fine grinding and dispersion of the product at relatively low energy consumption lead to the widespread use of vibratory grinding. The constructive scheme of the mill is developed, in which the flat vertical vibrating field provides lifting of a part of loading and by means of the transport-reloading device carries out its continuous adjustable movement from one grinding chamber to another, thereby circulating-spatial movement of the environment in which there is a grinding process. shock interaction of grinding bodies and material that is crushed. The priority direction of development of science and technologies at the modern level is the development, creation and implementation of new generation mechatronic systems. One of the most important rules for the construction of vibrating mills is the need to maximize the degree of their automation in order to increase productivity, improve the quality of grinding and reduce the cost of the process. Also in the article the structural model of the controlled vibromill with spatial-circulating loading movement which at change of weight of a working body in the course of separation and unloading of the crushed material from a grinding chamber constantly adapt to a resonant mode of work at the set technologically optimum parameters (productivity) and the minimum power consumption.
