Low-noise ball grinder

Abstract

The invention discloses a low-noise ball grinder which comprises a discharging opening. One end of the discharging opening is fixedly connected with an enclosure. The upper portion of one end, far away from the discharging opening, of the enclosure is fixedly connected with feeding openings. A motor is arranged on the side face, far away from the discharging opening, of the enclosure. The motor is arranged below the feeding openings. A rotor of the motor is connected with a rotating shaft. The rotating shaft stretches into the axis of the enclosure and extends to the other end of the enclosure. A support is arranged on the bottom face of the motor. An anti-vibration pad is fixedly connected to the bottom end of the support. The end, far away from the motor, of the rotating shaft is sleeved with a bearing pedestal. Stabilization devices are arranged on the lower side face of the enclosure. A noise reduction and vibration prevention device is adopted in the enclosure. According to the low-noise ball grinder, a novel noise reduction device is adopted, a structural layer is additionally mounted in the enclosure, and therefore the intensity of generated noise is reduced, noise transmission is effectively cut off, and the decibel of the noise is lowered; and a noise reduction shell is additionally mounted on the outer portion of the enclosure, and therefore noise transmission is further stopped.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a low-noise ball mill. Background technique [0002] The mechanical equipment is very extensive, and the ball mill is one of the important components. The ball mill is the key equipment for crushing the material after it is crushed. It is widely used in the production industries of cement, silicate products, new building materials, refractory materials, fertilizers, non-ferrous metal beneficiation, glass ceramics, etc., for dry or wet grinding of various ores and other grindable materials. The ball mill is It is composed of a horizontal cylinder, a hollow shaft for feeding and discharging materials, and a grinding head. The cylinder is a long cylinder with a grinding body inside. The cylinder is made of steel plate and fixed with a steel liner. The grinding body is generally Steel balls are loaded into cylinders according to different diameters and certain proportio...

AI Technical Summary

Problems solved by technology

Since the working principle of the ball mill is friction and collision, and the processed materials are all hard materials, the noise and vibration generated by collision and friction are relatively large. When there are people near the ball mill, they will feel noisy and uncomfortable. Working in an environment that also affects workers' health
