How to deal with the problem of roller teeth wear of tire cr

It is mainly suitable for grinding tires, wire tires, steel wire tires and various waste rubber products or scraps to make it into rubber powder and achieve the required fineness (mesh). Tire shredder has small investment, low cost and benefits Large, easy to operate, save time and effort, energy saving and environmental protection features! It is often used in the early stage of waste recycling in my country to provide reliable quality equipment for volume reduction and volume reduction. However, in the tire crusher, the roller teeth are a key wearable component, and the phenomenon of wear often occurs. Faced with the phenomenon of roller wear, how should we respond?1. Increase the hardness of the roller teeth: To increase the hardness of the roller teeth, the surface of the roller teeth is surfacing so that the degree of the tooth surface reaches above HRC58;2. Reasonable distribution of high and low teeth: Due to the abnormal wear of roller teeth, all teeth are ground to the same height, and it is no longer possible to distinguish the specific positions of the original high and low teeth. The distribution plan can be formulated according to the number and layout principles of high teeth and low teeth, and a mark should be made at the place of high teeth to enable accurate construction during welding;3. Surfacing on the roller teeth: Since the material of the roller teeth is high manganese steel alloy steel, the welding performance is relatively poor. High technical content is required for electrode material selection and surfacing construction. After selecting the appropriate wear-resistant electrode, surfacing directly on the surface of the roller teeth, using 5mm transition layer and 15mm wear-resistant layer for the high teeth, and repairing the low teeth by 2mm~5mm;4. Surfacing method: first disassemble the tooth plate from the crusher rotor and lay it flat. All the parts that need to be welded are polished to a metallic color with a polisher. A DC welding machine is used, the welding wires are reversed, and a single pass welding process is used for welding. The current of the wear layer is controlled at 150~180A, and the current of the transition layer is controlled at 90~110A. Control the temperature of the welding layer to be below 100 degrees Celsius, lay-up welding to the required thickness, the thickness of the single layer is controlled at 1.5mm~2.0mm.
