Description

Technical Field

[0001] The utility model belongs to the technical field of roller edges of roller mills and relates to a novel modular alloy roller edge for a roller sleeve of a roller mill. Background Art

[0002] Roller mill is developed based on the "laminated crushing principle" and has been widely used in crushing industries such as mining, building materials, and metallurgy. It consists of a pair of relatively rotating squeezing rollers, the roller edges at both ends of the squeezing rollers and the side baffles to form a closed crushing chamber. The material is compacted and crushed by the high-pressure force of the squeezing rollers; since the side baffles cannot completely fit the roller edges, a certain gap should usually be left. The roller edges are easily worn, fallen off, broken, and cracked due to material squeezing or encountering metal foreign objects. They should be repaired in time after wear, otherwise the "side effect" will be aggravated, the amount of returned materials will increase, the crushing effect will be reduced, and the overall wear rate of the roller surface will be accelerated.

[0003] In order to solve the problem of roller edge wear resistance, the existing alloy roller edge structures mainly include U-groove, T-groove and other structures.

[0004] Although the wear resistance of the existing alloy roller edge structure has been improved, the following problems still exist:

[0005] U-shaped and T-shaped alloy roller edge structure: U-shaped groove and T-shaped groove are processed on the end surface of the roller sleeve base, and the corresponding U-shaped and T-shaped alloy roller edges are embedded in the groove;

[0006] Disadvantages: The U-groove and T-groove structures on the end face of the roller sleeve base are extremely difficult to process and require special CNC equipment; the U-shaped and T-shaped alloy roller edges are difficult to manufacture and require high dimensional accuracy and high manufacturing costs; the clearance between the roller edge and the groove is too large, and the roller edge is very easy to fall off, break, and crack when encountering material extrusion or metal foreign matter; online replacement and maintenance are difficult, and special tools are required to pry out the remaining roller edge before replacement.

[0007] In summary, the utility model provides a novel modular alloy roller edge for a roller sleeve of a roller mill. Summary of the invention
