Working principle and characteristics of three-roll mill

How it works: The natural hopper is added by the middle and rear two rollers and two baffles. The opposite asynchronous rotation of the middle and rear rollers leads to violent friction and overturning of the raw material, and the strong shearing external force destroys the structural stress between the molecules in the raw material particles. After the high-speed secondary grinding of the middle and front two rollers, rapid crushing and dispersion can be achieved, and various raw materials can be uniformly mixed.

The three-roll mill is suitable for grinding products with high viscosity and fine particle size. Complete specifications, non-standard design, customization, products are exported at home and abroad.

The three-roll mill can be installed horizontally or slightly inclined. It achieves the grinding effect through the mutual extrusion of the surfaces of the three horizontal rollers and friction at different speeds. The steel drum can be hollow and cooled by water. Add material between the middle and rear rolls. Because the three drums rotate in different directions (speed increases from back to front), it has a good grinding effect. After grinding, the material is scraped off by scrapers installed in front of the front rollers.
