Double-vibration barrel-shaped stirring mill

Abstract

The invention provides a double-vibration barrel-shaped stirring mill. Materials can be strongly ground and dispersed, and the double-vibration barrel-shaped stirring mill is good in grinding grain size and high in production efficiency. The double-vibration barrel-shaped stirring mill comprises an upper inner mill rotating barrel, the upper inner mill rotating barrel is a hexagonal barrel, a lower inner mill rotating barrel connected with an outer mill barrel is arranged outside the upper inner mill rotating barrel, and a grinding channel is formed among the upper inner mill rotating barrel, the lower inner mill rotating barrel and the outer mill barrel. Grinding media are placed in the grinding channel, a feeding opening communicated with the grinding channel is formed in the center of the bottom end of the lower inner mill rotating barrel, the top end of the upper inner mill rotating barrel and the top end of the outer mill barrel are connected with a separator, a discharging channel is formed by the matched portions of the upper inner mill rotating barrel, the outer mill barrel and the separator, a discharging opening is connected with the discharging channel, the upper inner mill rotating barrel is connected with a driving device, and the lower inner mill rotating barrel is connected with a vibration device.

Description

technical field [0001] The invention relates to the technical field of liquid material dispersing machinery, in particular to a double vibrating cylinder stirring mill. Background technique [0002] In the chemical industry, dispersion engineering has always been an important part, including coatings, paints, inks, dyes, printing, pesticides, etc. must use dispersion engineering, the original various mixing mills, mostly use dispersion [0003] The high-speed rotation of the blade or pin and the grinding action of the grinding medium cause the particles in the slurry to be subjected to forces such as impact, friction, grinding and shearing to realize the dispersion and grinding of the particles. However, due to the large grinding space, the dispersion The centrifugal force generated by the rotation of blades or pins is limited, so that the grinding medium is easy to deposit when it is still. The bottom of the cylinder is not easy to start, and the beads are fragile, which gr...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems of low efficiency, high energy consumption and unsatisfactory dispersion effect of existing stirring mills, the present invention provides a double vibrating cylinder type stirring mill, which can powerfully grind and disperse materials, and has better grinding particle size, high production efficiency
