The rotational speed of the conveyor pulley determines the speed of belt, which affects the conveying capacity of the belt conveyor and the production capacity of coal mining work. Because of the bad working environment and improper use and maintenance in the coal mine, many conveyor pulleys need regular maintenance and the main reasons for regular maintenance of the conveyor pulleys are as follows：
1) The belt of conveyor pulley is worn so badly that the offset of rubber belt occurs.
2) The roller shaft is bent and deformed under the action of belt tension.
3) The serious oil leak causes the burn out of the shaft inside the shaft block.
For this reason, the following put forward corresponding improvement measures according to the above reasons.
Improvement of the ceramic roller plastic bag wrapped up on conveyor pulley At present, the most of the conveyor pulleys adopted hot vulcanization cladding.Its technical characteristics is below: before the assembly of the conveyor pulley, we put the sheet on the lathe first, and then turned about 2~3mm deep screw thread grooves with the middle of the sheet as the boundary and brushed two layers of adhesive (iron adhesive, rubber adhesive). We then pressed the raw rubber plate solidly on the sheet and put into a vulcanized steam furnace heated to 180 degrees Celsius for vulcanization.After the vulcanization, put it on the lathe turn the rubber plate into a pattern. And finally we can assemble the shaft, the shaft block etc.
Its disadvantages are below: under hot vulcanization, for its low vulcanization pressure, high sulfur content and poor wear resistance, the roller coating processed is easily aged and degummed in the use. Its disadvantages are below: under hot vulcanization, for its low vulcanization pressure, high sulfur content and poor wear resistance, the roller coating processed is easily aged and degummed in the use. Besides low adhesion to the conveyor belt often causes the offset of the belt. By the cold vulcanized ceramic cladding process, we can solve this problem.
By this, the cold vulcanized ceramic cladding process can solve this problem. It can improve the friction between conveyor pulley and the conveyor belt to reduce the offset of the conveyor belt, and it also has a self-cleaning function, which can reduce the adhesion of materials on its surface reducing the deviation and wear of the conveyor belt. With this rubber sheet, the service life of it is 4 times more than the original casting rubber.
