Description

Technical Field

[0001] The utility model relates to the technical field of a grading three-roller grinder, in particular to a grading three-roller grinder for producing powder cosmetics. Background Art

[0002] Roller mills can be divided into two-roller, three-roller, four-roller and multi-roller. Three-roller mills are commonly used in industry. Roller mills are widely used in wet grinding of raw materials in chemical industries such as paints, coatings, plastics, rubber, lead cores, leather, medicine, food, cosmetics and insulating materials. It has multiple functions such as crushing, dispersing, emulsifying homogenization, and color matching, and can make the raw materials highly evenly mixed. The three-roller mill mainly relies on three horizontally arranged rollers, which squeeze each other and achieve the grinding effect through friction at different speeds. The rotation directions of the three rollers are opposite, and the speed increases step by step. This design helps the material to be effectively ground, sheared and compressed between the rollers. The material is usually added between the middle roller and the rear roller. Using the faster speed of the middle roller and the slower speed of the rollers on both sides, the material is forced to be sheared and compressed between the rollers, thereby achieving particle size refinement, uniform mixing and dispersion. This design not only helps to improve the fineness of the material, but also prevents the accumulation of materials and the occurrence of stringing. The ground material is discharged from the lower discharge port to complete the grinding process.
