Groove type roller

product details

Trough idlers are generally composed of two side idlers and one parallel idlers. The idlers have good lubricity, and will not be stuck in specific environments. They have strong corrosion resistance and aging resistance, and are easy to operate and install, and operate stably.

The angle range of the groove type roller is generally 35 ° and 36 °. The groove type roller can remove the belt dirt, and has the best effect on the slope belt with high force and low resistance. The double section roller can reduce the heavy pressure points of the belt on the ceramic roller, and the hollow device of the roller can allow the belt to fall off on its own without sticking to the roller, which can extend the service life of the roller. High economic benefits can reduce the overall cost of belt conveyors and decrease maintenance hours.

Application scope

Groove type rollers are widely used in outdoor environments with high dust and corrosiveness, such as mines, power plants, steel mills, stone factories, cement factories, coal washing plants, salt factories, alkali factories, fertilizer factories, docks, and other transportation sites.

classification

There are various types of groove shaped rollers, including ordinary rollers, forward leaning rollers, quick change bearing rollers, hanging rollers, triple chain rollers, reversible rollers, variable groove angle rollers, transition rollers, V-shaped rollers, etc.

Quality standards for groove type rollers

1. It should have good corrosion resistance characteristics. Because many dust particles in these environments are acidic, alkaline, and salty, which can cause corrosion to the rollers, we must choose products with strong corrosion resistance.
2. It should have a certain strength and excellent friction resistance. Because in these environments, particles such as stone powder and coal powder are hard and have high surface friction.
3. The surface should be smooth and have a low coefficient of friction. This reduces the friction coefficient with the conveyor belt and prevents material adhesion, greatly reducing the driving force of the winch.
4. The sealing performance must also be good. This is mainly to prevent the leakage of oil and grease, which can enable the rolling shaft to be used for a long time.
5. Long service life is required for all equipment. A long service life means that we will save costs to a certain extent. Therefore, when choosing, we should choose rollers with good quality and long service life. The above are the quality standards for groove rollers. We can choose according to these standards when making choices, so as to select good equipment.

characteristic

1. The groove type roller has the characteristic of corrosion resistance: acid, alkali and salt have no corrosive effect on it.
2. The groove type roller has strong hardness and wear resistance.
3. Good sealing performance: The groove type roller is fully sealed, with plastic labyrinth sealing rings at both ends, which prevent oil and grease leakage and can keep the rolling shaft for a long time; The groove roller operates in a fully sealed state.
4. Ceramic surface of groove type roller: forms an oxide film, has a smooth surface, does not adhere to materials, has a low friction coefficient in contact with the conveyor belt, and reduces the driving force of the winch.
5. Long service life of groove type rollers: Groove type rollers have 2-5 times longer service life than steel rollers, and can reduce belt wear, prevent belt running, and extend belt service life.
6. Low operating costs: Groove rollers can reduce the overall cost of belt conveyors and decrease maintenance hours.
