Rollers of the pipe body corrosion resistance, wear resistance. A higher percentage of sulfur in the coal mine, most of the water, 4.5 mm thick steel pipe roller, pipe body corrosion is around 1 year, the shortest only 5 months or so; In coking plant, the sinter, pellet mill, wet conveying steel slag, slag, steel pipe roller tube body of the life expectancy for six months or so, a lot of 3 months to be ground breaking, serious only 10 days. Tube body, roller can not scrap?  

    Therefore, roller of tube body corrosion resistance and wear resistance is one of the keys to ensure its longevity. And the performance indicators are blank at home and abroad, foreign coverage of the roller life 90000 hours, in severe environment pollution, corrosion, wear and tear, steel pipe roller is impossible! Completely sealed, flexible rotation, anticorrosive wearing only have a combination of these three conditions, roller can achieve ideal use effect. Roller frequent damage severely restricts the safety and reliability of the belt conveyor and conveyor operation rate. And the service life of the roller and its use has close relation with the environment, if the roller revolving resistance on average 1 n, or less bearing never pollution, keep good lubrication condition. Here we make a brief introduction:
The rotation of the roller resistance. Life is the life of the roller bearing, and bearing life is closely related with the rotation of the roller resistance force. In to ensure good lubrication of the bearing state, rotating roller 1 n or less of the resistance, bearing life can reach 150000 hours; Rotating resistance 2.5 N - 3 or less N roller, bearing life of 50000 hours; Rotating resistance or less 5 n - 8 n roller, bearing life can't more than 10000 hours, visible roller rotating resistance and service life is also very close.
   In a better environment such as mine, power plant, dock, food, etc., the service life of roller is up to fifty thousand hours. In the coal mine, steel mills, cement plants, etc. These drench water, coal slurry and dust pollution of environment, the nylon roller's average life expectancy is only about 1 year.
Rollers of the sealing performance, about the life of the bearing, about the life of the roller tube body the three factors affecting the service life of the roller.
   Drive roller roller of the sealing performance is the most important. Dust or water enter the bearing, the grease in the bearing will be "eaten", bearing no lubrication, which reduced hundreds life, will soon expire, or jammed by dust, rollers are also immediately discarded. Labyrinth contactless sealing is the most ideal sealing structure of the roller. If muddle never contaminated water, dust, the antioxidant lithium base grease in the bearing can guarantee calcification in 30 years, bearing always works in good lubrication condition, on the premise of rotation resistance or less 1 n, normal use life should be 150000 hours in the roller.
