Rotary mute ball grinding mill

Abstract

The invention provides a rotary mute ball grinding mill. The rotary mute ball grinding mill comprises a rotary shaft, a ball grinding mill body and a chain wheel, wherein the ball grinding mill body is horizontal; the rotary shaft is inserted into the ball grinding mill body; the ball grinding mill body comprises a ball grinding barrel; a feeding hole and a discharging hole are formed in the two ends of the ball grinding barrel respectively; a feeding lining is arranged at the connection part of the feeding hole and the ball grinding barrel; the ball grinding barrel comprises an outer ball grinding barrel and an inner ball grinding barrel; a sound insulation layer is arranged between the outer ball grinding barrel and the inner ball grinding barrel; the inner ball grinding barrel is internally provided with a stirring device; the stirring device comprises a stirring rod and a scraping plate; and the ball grinding mill body and the chain wheel are symmetrically distributed along the rotary shaft. According to the rotary mute ball grinding mill, the stirring direction of the stirring device is opposite to the rotary direction of the ball grinding mill body; the movement speed of the ball grinding mill is increased through the stirring device which rotates in the opposite direction, and an effective crushing region is increased; the sound insulation layer is arranged between the outer ball grinding barrel and the inner ball grinding barrel, so that the noises are effectively lowered; and bidirectional rotation and muteness are effectively combined and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ball mills, in particular to a rotary silent ball mill. Background technique [0002] The ball mill is the key equipment for further crushing after the material is destroyed. It is widely used in the production industries such as cement, silicate products, new building materials, refractory materials, chemical fertilizers, ferrous and non-ferrous metal beneficiation, and glass ceramics. Other grindable materials are subjected to dry or wet grinding. [0003] Ball mills are generally divided into two types: ordinary cylinder ball mills and stirring ball mills. Most of these two ball mills have disadvantages such as complex structure, small effective pulverizing area, high noise, and low production efficiency. Contents of the invention [0004] The invention aims to solve the deficiencies of the prior art, and provides a rotary silent ball mill. [0005] In order to achieve the above object, the present...
