Safe high vibration strength elliptical vibromill

Abstract

The invention discloses a safe high vibration strength elliptical vibromill which comprises a motor, a barrel rack, an upper barrel, a lower barrel, a frame, a base and an excitation dynamic damper. The safe high vibration strength elliptical vibromill is characterized in that by adopting the barrel with an elliptical movement locus, the motor is fixedly arranged on the frame, the motor is coupled with a main shaft of the excitation dynamic damper by virtue of a coupler; the barrel rack is mounted on the frame, the upper barrel is arranged on the top of the barrel rack and the lower barrel is arranged at the bottom of the frame; a steel ball, a steel rod or other grinding media are mounted in the barrel; the upper barrel and the lower barrel are arranged at eccentric position of the main shaft of the excitation dynamic damper by using a flange disc with a bearing by virtue of the barrel rack. The safe high vibration strength elliptical vibromill disclosed by the invention has the advantages of increasing the work efficiency by times, eliminating the vibratory load, moving elliptically, being high in vibrating strength, safe and reliable and the like.

Description

technical field [0001] The invention relates to processing equipment for crushing and ultrafine crushing of brittle solids, in particular to processing equipment capable of rapidly crushing superhard and brittle materials into ultrafine powders of different particles. Background technique [0002] Vibrating mills are used in many industrial industries such as metallurgy, coal, chemical industry, and mining in the national economy. Its characteristics are: relatively simple structure, reliable operation under certain conditions, and high crushing efficiency compared with other types of grinding equipment; its vibration intensity is mostly controlled within the range of about 10g (g is the acceleration of gravity), resulting in low production efficiency. The production efficiency of the vibration mill is directly proportional to the vibration intensity. [0003] Thus, the inventor invented a vibration-absorbing type centrifugal vibratory grinding machine in May 2009, as follo...

Problems solved by technology

[0005] Yet the inventor finds after using for a period of time that this mill also has some defects: 1. When the vibration amplitude is too large, it is difficult to feed the material, and there is still an energy-depleted area in the lower cylinder

2. The vibration load is transmitted to the spring, frame and foundation, which seriously affects the service life of springs, motor couplings and other components, and has high requirements for the installation foundation

And from the traditional vibration theory, the negative side effects of vibration of vibrating machinery cannot be eliminated
