1. Groove idlers have corrosion resistance characteristics: acid, alkali and salt have no corrosion effect on them.
2, groove roller hardness: wear resistance.
3. Good sealing performance: groove idlers are fully sealed, with plastic labyrinth sealing rings at both ends, so that greasy grease will not leak and the rolling shaft can be maintained for a long time; Groove idlers operate under full seal condition.
4. Ceramic surface of groove idler: formed oxidation film, smooth surface, non-adhesive material, low friction coefficient in contact with conveyor belt, reduced lifting driving force.
5. Long service life of groove idler: the service time of groove idler is 2-5 times longer than that of steel idler, and it can reduce the wear of belt, prevent the belt from running, and extend the service life of belt.
6. Low operating cost: trough idlers can reduce the overall cost of belt conveyor and reduce maintenance time.
Trough roller is widely used in the environment with large dust and high corrosion in the open air, such as mine, power plant, steel plant, stone plant, cement plant, coal washing plant, salt plant, alkali plant, chemical fertilizer plant, wharf and other transportation places.
