Technical Field

[0001] This utility model relates to the field of high-pressure roller mill roller body technology, specifically a high-pressure roller mill roller body structure that can be quickly replaced. Background Technology

[0002] The rollers of a high-pressure roller mill are the core working components of the equipment. Their main function is to apply high pressure to the material through pairs of counter-rotating rollers, causing the material to break, densify, and develop micro-cracks under the action of extrusion and grinding. Through the pressure transmission of the roller surfaces, large pieces of material are broken into smaller pieces, while the extrusion force between the rollers is used to achieve ultra-fine grinding of the material, greatly improving the efficiency of subsequent processing.

[0003] The high-pressure roller mill disclosed in the existing patent publication number CN214553857U includes a base and a feed hopper. The base is respectively provided with a frame base and a feed hopper support. The feed hopper support is connected to the feed hopper located between the upper parts of the two frames. The frame base and the feed hopper support are respectively set on the base to ensure that the frame base and the feed hopper support are on the same horizontal plane, which facilitates installation and occupies a small area.

[0004] During long-term operation, the roller body inevitably experiences wear due to continuous contact and compression with the material. However, the disassembly and replacement process of the roller body in the above-mentioned device requires the removal of a large number of screws, which is quite complex and cumbersome, and consumes a lot of time. To address these issues, a roller body structure for a high-pressure roller mill that can be quickly replaced is proposed. Utility Model Content
