Three-roll grinder is referred to as three-roll grinder for short. Three-roller grinder can be divided into experimental three-roller grinder and production three-roller grinder. Three-roller grinder is suitable for manufacturing paints, inks, pigments, plastics and other slurries. Working principle of three-roll grinder: Three-roll grinder achieves grinding effect through mutual extrusion of the surfaces of three horizontal rollers and friction at different speeds. Three-roller grinding machine is the most effective equipment for grinding and dispersing high viscosity materials.

trait

Three-roll mill, referred to as three-roll mill, is the most effective equipment for grinding and dispersing high-viscosity materials. Mainly used for grinding paint, ink, pigment, plastic, cosmetics, soap, ceramics, rubber and other liquid pastes and paste materials.

structure

The three-roll grinding machine has three rollers mounted on an iron frame, and the centers are in a straight line. It can be installed horizontally or slightly obliquely. The grinding effect is achieved by mutual extrusion of the surfaces of three horizontal rollers and friction at different speeds. Steel drums can be hollow and cooled with water. The material is added between the middle roller and the back roller. Because the rotating directions of the three rollers are different (the rotating speed increases from back to front in turn), a good grinding effect is produced. After grinding, the material is scraped off by a scraper installed in front of the front roller. ?

Usually, the roller of three-roll grinder adopts centrifugal casting chilled alloy cast iron, and the surface hardness is above HS70. After precise grinding and fine processing, the circular diameter of the drum can make the grinding fineness of materials reach about 15μm, so it can produce uniform and fine quality products. SM405 and S260 three-high machines are used for batch production, while SM 150 and S65 are used for small batch or laboratory use.
