Problems solved by technology

The higher the relative speed of the grinding medium, the greater the collision force and the better the grinding fineness; the action mode of a single disc or eccentric disc sand mill makes the effect of relative movement of the grinding medium not very ideal. The ideal fineness needs to be ground many times, the grinding time is long, the energy consumption is high, and the efficiency is low

Abstract

The invention provides a horizontal sand mill of a combined rotary dispersion disk grinding structure. The horizontal sand mill of the combined rotary dispersion disk grinding structure is composed of a machine frame, a motor, a main shaft, a grinding unit, a material pump and an electric system. The grinding unit is of the rotary dispersion disk grinding structure combining a crescent round dispersion disk and an eccentric dispersion disk, and is composed of an outer grinding cavity barrel body, an inner grinding cavity barrel body, the main shaft, a discharge separation device, a discharging end sealing cover, an abrasion-resistant plate, a barrel end sealing cover plate and a ball discharging valve. The horizontal sand mill of the combined rotary dispersion disk grinding structure has two different shearing forces and can change the movement mode of balls and materials in the barrel bodies, thereby increasing the relative movement speed and impact probability of balls and material particles, obtaining higher relative movement speed and impact force compared with a single round disk or eccentric disk, enabling materials to reach the ideal fineness as soon as possible, and obtaining higher grinding efficiency. The horizontal sand mill of the combined rotary dispersion disk grinding structure further has abrasion resistance and corrosion resistance, is long in service life, is convenient to clean and replace, and is widely applied to processing and production of paints, ink, pigment and other fields.

Description

technical field [0001] The invention relates to a horizontal sand mill, in particular to a horizontal sand mill with a combined rotating dispersing disk grinding structure, which belongs to the technical field of grinding machinery. Background technique [0002] At present, most of the sand mills used in industries such as coatings, inks, inks, pigments, and dyes are single disc or eccentric disc grinding structures. The basic principle is: a closed cylinder is equipped with media for grinding such as Zirconium beads, glass beads, etc., move the media in the cylinder through the dispersing disc installed on the rotating shaft, so that the media will move relative to each other, and the materials to be ground will pass through the media to achieve the effect of crushing. The higher the relative speed of the grinding medium, the greater the collision force and the better the grinding fineness; the action mode of a single disc or eccentric disc sand mill makes the effect of rel...
