Background
Crushers generally handle larger pieces of material, with coarser product sizes, typically greater than 8 mm. The structure is characterized in that certain gaps are arranged among the crushing pieces and the crushing pieces are not in contact with each other. The crusher can be divided into a coarse crusher, a medium crusher and a fine crusher. Generally, the ore mill is used for processing fine materials, and the product granularity is fine and can reach 0. 074 mm, even finer. The structure is characterized in that the crushing components (or media) are contacted with each other, and the adopted media are steel balls, steel bars, gravels or ore blocks and the like. However, some machines have both functions of crushing and grinding, such as an autogenous mill.
The existing crushing roller has the technical defect of low disassembling efficiency.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the utility model provides a dismantle convenient crushing roller, includes the pivot, be connected with the crushing roller in the pivot, through lock ring and pivot pin connection between crushing roller and the pivot, the upper surface coating of crushing roller has one deck resistant friction layer, the thickness on resistant friction layer is 1-2mm, a plurality of louvres have been seted up on the both sides face of crushing roller.
Furthermore, the diameter of the heat dissipation holes is 1-1.2 mm.
Furthermore, the surface of the crushing roller is provided with a plurality of crushing teeth, and the crushing teeth and the crushing roller are of an integrated structure.
Furthermore, the crushing teeth are annularly arranged on the surface of the crushing roller, and the side surfaces of the crushing teeth are triangular.
Furthermore, the height of the crushing teeth is 2-3mm, and the side surfaces of the crushing teeth are equilateral triangles.
Furthermore, the locking ring is connected with the side surface of the crushing roller through threads, a circle of internal threads are arranged on the inner surface of the locking ring, a locking seat is arranged on the side surface of the crushing roller, and a circle of external threads are arranged on the outer surface of the locking seat.
Further, shaft pin holes are respectively formed in the locking ring and the rotating shaft.
Furthermore, the number of the crushing rollers is two, the rotating shafts of the two crushing rollers are respectively connected with a gear, and one of the rotating shafts is connected with a driving motor.
The technical scheme adopted by the invention has the beneficial effects that:
according to the crushing roller, the crushing roller is connected with the rotating shaft through the locking ring and the shaft pin, the upper surface of the crushing roller is coated with the friction-resistant layer, the thickness of the friction-resistant layer is 1-2mm, the two side surfaces of the crushing roller are provided with the plurality of heat dissipation holes, the structure is adopted, the crushing roller is convenient to mount and dismount, the friction resistance of the crushing roller is improved due to the structural design of the friction-resistant layer, the service life of the crushing roller is prolonged, the heat dissipation performance of the crushing roller is improved due to the structural design of the heat dissipation holes, and heat generated in the crushing process can be dissipated in time.
