Description

Technical Field

[0001] The invention relates to the technical field of grinders, in particular to a vertical hydraulic three-roll grinder. Background Art

[0002] The vertical hydraulic three-roller grinder is an efficient industrial grinding equipment with three high-precision rollers. It is widely used in chemical, coating, ink and other industries. It can finely grind various materials, refine material particles to the required particle size, improve the dispersion and uniformity of materials, and significantly improve product quality and production efficiency. The vertical hydraulic three-roller mill usually consists of a frame, three rollers, a control system and a hydraulic system. The material to be ground is evenly fed into the space between the three rollers through a feeding device. There is a speed difference between the rollers. The material is rolled into the space between the rollers under the friction and shear force of the rollers. During the grinding process, the material continuously circulates between the rollers, gradually being refined and evenly dispersed to complete the grinding of the material. Different types of materials require different rollers. For example, when processing materials with higher hardness, high-hardness rollers are required; when grinding softer materials, conventional rollers are used; when grinding corrosive materials, corrosion-resistant rollers are required. However, the upright hydraulic three-roller grinder in the prior art is not convenient for replacing rollers, which causes limitations.
