The idler is an important part of the belt conveyor, with many types and large quantities. The function is to support the belt, reduce the running resistance of the belt, and ensure the smooth operation of the belt. The operation of the idler must be flexible and reliable. Reducing the friction between the conveyor belt and the idler plays a key role in the life of the conveyor belt.It is not easy to manufacture a high-quality idler. The criteria for judging the quality of idlers are as follows: radial runout of idlers; flexibility of idlers; axial movement.You can use them in industries of Mining, Steel mill, Cement plant, Power plant, Chemical Plant, Sea Port, Storage, etc.The Advantage of the Trough Roller&Idler:
| 1. The trough roller has the characteristics of corrosion resistance: acid and alkali salts are difficult to corrode it. |
| 2. Trough roller have strong hardness: strong wear resistance. |
| 3. Good sealing: the trough roller is fully sealed, and the two ends are equipped with plastic labyrinth sealing rings, and the oil grease will not leak, which can make the rolling shaft long-term; The slotted idler is operated in a fully sealed state. |
| 4. Long service life of the trough roller: the slotted roller is 2-5 times longer than the steel roller, and can reduce the wear of the belt, the belt does not run, prolonging the service life of the belt. |
| 5. Low operating costs: The trough roller can reduce the comprehensive cost of the belt conveyor and reduce the maintenance man-hours. |
| 6.Trough rollers are widely used in open-air dust and highly corrosive environments, such as mines, power plants, steel mills, stone mills, cement plants, coal washing plants, salt plants, alkali plants, fertilizer plants, docks and other transportation places often use trough rollers. |
The specification Range of the Trough Roller&Idler:
The Form of the Trough roller:
| 1.Roller idlers Dia 50mm-219mm, length 190-3400mm, which are used in the steel industry, harbor, coal industry, power industry, cement industry, etc |
| 2.Tube: Q235 |
| 3.Shaft: 45# STEEL |
| 4.Bearing: Single & Double Row Deep Groove Ball Bearing 2RZ&2Z with C3 clearanc |
| 5.Seals: Grease retaining inner seal with Multi-stage Labyrinth and Retention Cap with Outboard Rubbing Flinger Seal. |
| 6. Lubrication: Grease is Lithium soap type grease with Rust Inhibitors. |
| 7. Welding: Mixed gas shielded arc welding end |
|
8. Painting: ordinary painting, hot galvanized painting, electric static spraying painting, baked painting.Besides we can manufacture the rollers and idlers according to the buyers' requirements. |
The Various Kinds of the Idler:
| Troughing idlers are the most common idler used on the carry side of the conveyor. Extending their life expectancy can be a challenge. Our proven seal design and low maintenance rollers lead to less downtime and increased profits. |
| Impact idler is used to absorb the shock of loaded material from chute at loading and transfer point, so as to protect belt from damage or deterioration. In order to ensure good bonding strength, the impact rubber rings are made of wear and impact resistant rubber are vulcanized. |
| Friction self-aligning idler roller is used to adjust the belt deviation, it has a strong ability to prevent belt from being damaged and sideslip. It is based on the principle of idler curvature and frcition to prevent and correct belt sideslip. Friction f self-adjusting conveyor roller has great ability to protect conveyor belt from damage and running offline. When conveyor belt runs offline, which side the conveyor belt runs to, the frictional force of this side will be increased. |
| Self-aligning Idler (Training Idler) offered comprise quality assured range of self-aligning conveyor idlers that are suitable for use in tracking of both return and load-carrying side and find use in reversible conveyor belts, high-load conveyor belts slow moving conveyor belts. |
| Steel Screw Idler are used on the return side of the belt as belt cleaner. Spiral steel welded on the spiral roller act as a screw and pushes the build-up material on the center to the edge of the belt, return roller. Our products are widely used in thermal power generation, harbours, cement plants, metallurgy and as well as the light duty conveying devices for industries. |
| Rubber Disc Idler used in acid and alkali resistant industry of conveyor, comb idlers can replace the metal roller , nylon roller, long life , easy installation, custom center smooth transportation, reduce conveyor belt deviation and protection conveyor belts and other characteristics . |
| Flat Return Idler is mainly used for supporting materials and belts. Upper flat idler and lower flat idler are applicable to be fixed on conveyors used in port ,terminal, mine, cement plant, thermal power plant, grain silo/warehouse, sand plant, etc. |
The Application of the Various Idler:The Production Process of The Roller:1. The roller parts, roller skin and bearing seat should be cleaned before welding, and the inside of the roller skin should be brushed with anti-rust paint, and there is no undercut during welding.
2. When installing, fill up grease in the oil chambers before and after the bearing, and add 1/2 space of lithium-based grease in the sealing groove and the bearing.
3. After the idler roller is installed, under the action of 500N axial pressure, the axial displacement of the roller is not more than 0.7mm, and when the belt speed is less than 3.15m/s, the beating between the outer diameters of the roller is less than 0.7m.
4. The idler is at 1 After the horizontal and vertical drop test at a height of meters, the roller parts should meet the following requirements: (1) The spoke parts and welds should not be damaged or cracked, and the corresponding joints should not be loosened; (2) The axial displacement of the roller should not exceed 1.5 mm
5. After the installation is completed, it should be ensured that the rotation is dexterous, and the size of the installation is within the scope of the drawings.
6. Derusting and painting : Remove the rolling oxide rust and foreign matter The processing mating surface should be painted to prevent the oil from being exposed. The non mating surface should be painted with topcoat or primer, and the dry film thickness should be at least 350m.
The Laboratorial Research of The Roller: There are some criteria of the rollers,after the order is made,we will have the test to confirm the quality of the rollers.Only when the above items meet the standard, can be shipped and installed.
| 1. Radial runout of the roller | directly affects the stability of material transportation |
| 2. Flexibility | affects the service life of the roller and the belt, as well as the driving power of the whole machine |
| 3. Axial string momentum | affects the service life of the roller |
| 4. Waterproof performance | |
| 5. Dustproof performance | |
| 6. Axial bearing capacity | |
| 7. Impact resistance | |
| 8.Rotational resistanc | affects the service life of the belt |
