Rubber Disc Return Rollers are designed to absorb the impact of large loads of ore falling onto conveyor belts.Which is an important part of the belt conveyor, it can withstand more than 70% of the resistance of a single belt conveyor. It is used to support the conveyor belt and material. We offer rollers in steel, nylon, ceramic or rubber. With years of design and manufacturing experience, We are a high-quality rubber sleeve idler (idler) server for the conveyor spare parts industry. Rubber sleeve idler is a kind of return idler. Return idlers are also known as parallel lower idlers. It is also the most commonly used lower roller. The function of the return roller set is to support the back part of the belt, reduce the running resistance of the friction between the belt and the skirt, and the drape of the belt does not exceed a certain limit to ensure the smooth operation of the belt. Belts to extend service life.For use in extreme environments: Iron Ore, Hard Rock, Gold Mining, Bauxite and all other extreme, moist and dusty environments.
The specification Range of the Rubber Disc Flat&V-type Idler:
The Form of the Rubber Disc Roller:
Ultimate Bearing Protection:
Advanced Sealing Arrangement : The arrangement is completely water tight and bearings are completely protected from moisture and grit.
High-impact Bearing and Seal Housing : Bearings are protected from the heavy impact from lumps of material.
High quality lubricant. We are lubricated for life.
Only the best quality bearing brands (SKF or FAG) are used in our products.
Cost Effective and Durable
Rubber Disc Return rollers are covered with a series of rubber rings of adequate thickness, which act to absorb the impact of large amounts of material falling onto the conveyor., which ensure the lifespan of the roller's bearings.
Energy Efficient:
The lighter weight than conventional Impact rollers , thus a significant reduction in energy or start-up costs on conveyor drives.Seal offers a low friction coefficient.Energy Efficient bearings ensures a low power demand for conveyors.
Highly Durable Roller Body:
Highly resistant to wear by abrasion.
Designed to operate in extreme temperatures, harsh operating conditions, and in highly-corrosive chemical or coastal conditions.
100% Belt Friendly:
Rubber Disc Return rollers are fitted with the same HDPE end caps, and does not damage belt. Its frictional characteristics results in less build up and decreased abrasive action on conveyor belts.
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 |
