The imapct idler is used to slow down the impact of the blanking material on the conveyor belt at the receiving place of the belt conveyor. It is a type of idler mainly developed for corrosive environments such as coal washing plants, coking plants, and chemical plants. Its toughness is ordinary. It is more than 10 times that of metal, and its life is five times that of traditional column shoes. The polymer material specially used for the roller body, its mechanical properties are similar to bronze, it has good wear resistance, and it has good self-lubricating properties, which does not damage the belt. The buffer idler has excellent anti-corrosion performance. The roller body and seals are made of polymer materials, which are corrosion-resistant. Used in corrosive occasions, the service life can reach more than 5 times that of ordinary idlers
The specification Range of the Impact Roller&Idler:
The Form of the Impact Roller:
| 1.Steel impact tube. |
| 2.Steel Reforcing ring. |
| 3.ZZ,C3,SKF,NTN,NSK.RKM high performancesealed for life bearings. |
| 4.Outer protective shield. |
| 5.Low firction dust up seal. |
| 6.Mild&Stainless steel stepped shafts. |
| 7.circlip bearing retention. |
| 8.Water&Dust resistant RS tripe labyrinth male/female preloaded seal. |
In terms of installation of impact idlers, one is to increase the density of installation; the other is to check frequently and replace damaged idlers in time. It is recommended to install a buffer air lock for the conveyor belt with a large blanking drop, and replace the buffer idler with a buffer bed. In terms of purchasing, according to the characteristics of the buffer idler, the following points should be noted: the radial runout of the idler, the flexibility of the idler, the axial movement, the dustproof performance of the idler, the waterproof performance, the axial bearing performance of the idler, Roller impact resistance, etc.
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 resistance | affects the service life of the belt |
The Package and Delivery of The Roller:
