Abstract

The invention relates to a vibration grinding method with active impact and rotational grinding of a grinding medium. A stepless speed regulation motor is used to drive an oscillating shaft, a grinding medium is arranged at the lower end of the oscillating shaft which is provided with an eccentric block, and the grinding medium and the eccentric block are fixed in a proper position of the oscillating shaft at a certain included angle, so that the excitation force mainly acts on the horizontal surface; and the grinding medium and the eccentric block rotate with the stepless speed regulation motor through a transmission device, and actively impact on a material under the action of the excitation force in a grinding chamber and generate rotational grinding with the rotation of the motor. The vibration grinding method provided by the invention has the advantages of high grinding efficiency, low energy consumption, fine grinding size, good spring force condition, and the like.

Description

technical field [0001] The invention belongs to the technical field of mineral grinding equipment, in particular to a vibration grinding method in which grinding media actively impact and rotate grinding. Background technique [0002] my country is a country with rich mineral resources. There are nearly 200 kinds of minerals that have been proven. The total mineral resources rank third in the world, second only to the United States and Russia, accounting for about 12% of the world's total mineral resources. Due to the difficulty of beneficiation or prospecting equipment, the conditions for the development and utilization of many mineral resources are poor. In the process of searching for mineral resources, it is necessary to analyze and test the minerals, so that the mineral samples must be crushed and ground before further analysis. [0003] The crushing of materials is a process that is widely used in industrial and mining enterprises. Most of the original mined materials ...
