1. Trough roller has the characteristics of corrosion resistance: acid, alkali and salt are difficult to corrode it.
2. Groove roller has strong hardness and wear resistance.
3. Good sealing: groove roller is fully sealed, with plastic labyrinth sealing rings at both ends, oil and grease will not leak, which can make the rolling shaft run for a long time; groove roller is in a fully sealed state.
4. Ceramic surface of trough roller: forming oxide film, smooth surface, non-adherent material, low friction coefficient with conveyor belt, reducing the driving force of hoisting.
5. Long service life of trough roller: trough roller is 2-5 times longer than steel roller, and can reduce belt wear, belt does not run, prolong belt service life.
6. Low operating cost: trough roller can reduce the overall cost of belt conveyor and reduce maintenance time.
Trough roller is widely used in open-air environment with large dust and high corrosiveness, such as zhoubanjia.com.cnwww.jinchengbanjia.cnwww.shaiwang.org.cnmine, www.yangquanbanjia.cnpower www.lizhumuju.cnwww.shuozhoubanjia.cnwww.xinplant, steel plant, stone plant, cement plant, coal washery, salt plant, alkali plant, fertilizer plant, wharf and all other transportation sites often use trough roller.
