The Conveyor Belt Idler is to support the conveyor belt and material weight. Conveyor Belt Idler operation must be flexible and reliable.Reducing the friction between conveyor belt and Conveyor Belt Idler plays a key role in the life of conveyor belt which accounts for more than 25% of the total cost of conveyor.Although the Conveyor Belt Idler is a small part in the belt conveyor, its structure is not complex, but it plays an important role in the operation of the belt.

There are six main types of common idlers.
1.Trough idlers are used to carry bulk materials. They are composed of three idlers, and the groove Angle is generally 300. Trough idlers can reduce the height of idlers, reduce the equivalent distance between idlers, and be used in places with smaller stiffness and space with the conveyor belt.
2.Cushioning idler is installed at the falling place of the conveyor, which can slow down the damage caused by the impact of falling material on the conveyor. It has strong toughness, corrosion resistance, flame retardant and anti-static, and is widely used in mining.
3.The aligning idler can correct the excessive deviation of the conveyor belt in the re-operation, prevent the conveyor belt from snaking, and ensure the stable operation of the conveyor belt. The conveyer belt that needs to be equipped with a self-aligning roller is generally equipped with a group of self-aligning idler for every ten groups of idler.
4.The most commonly used lower idler for return. Large conveyor can also use two idler, two idler arranged into a V-shaped to prevent deviation and high bearing capacity, most of the practice is every seven groups of parallel idler set 3 groups of V-shaped and V-shaped forward down idler.
5.Excessive idler is suitable for large volume, long distance, conveyor belt tension and important conveyor generally should be set transition section, transition section is the place where the transition roller is arranged.
6.The spiral idler is used to clean the material adhered on the bearing surface of the conveyor belt. Its function is the same as that of the cleaner. Generally, the lower roller closest to the idler of the conveyor head is designed as the spiral idler.
Structure and Feature:
1. Belt conveyor supporting roller, small resistance, the total indication jump (T.I.R.) is low, which can reduce the wear of the belt.
2. Good sealing: Conveyor Belt Idler is fully sealed, both ends are equipped with plastic labyrinth sealing ring, grease will not leak, can make the rolling shaft for a long time; Conveyor Belt Idler operate in a fully sealed state.
3. Long service life of Conveyor Belt Idler: Conveyor Belt Idler is 2-5 times longer than steel idler, and can reduce belt wear, belt does not run side, prolong the service life of belt.
4. Low operating cost: trough roller can reduce the overall cost of belt conveyor, reduce maintenance time.
5. The surface is smooth, does not adhere to the material, and the friction between the roller and the conveyor belt is small, reducing the driving force of winching.

Factors affecting the quality of Conveyor Belt Idler:
1. Radial runout of Conveyor Belt Idler (this index directly affects the stability of material conveying)
2. Axial string momentum (directly affects the service life of idlers)
3. Flexibility (affect the service life of the idler, the service life of the belt, and the driving power of the whole machine)
4. Waterproof performance (affect the service life of roller)
5. Dustproof performance (affect the service life of roller)
6. Axial bearing capacity (affecting the service life of idlers)
7. Impact resistance (affecting the service life of idlers)
8. Rotating resistance (affecting the service life of the tape)
Maintenance
1. The normal service life of idler is more than 20000h, generally no maintenance is required. However, according to the size of the use place and load, the corresponding maintenance date should be formulated, timely cleaning and oiling maintenance, timely cleaning of floating coal, etc. The Conveyor Belt Idler with abnormal sound and does not turn should be replaced in time.
2. When replacing the bearing, the opening of the bearing cage must be outward. After the bearing is loaded into the Conveyor Belt Idler, proper clearance should be maintained to avoid crushing.
3. The labyrinth seals shall use the original parts, and shall be installed into the Conveyor Belt Idler separately during assembly, and shall not be assembled together.
4. When using the Conveyor Belt Idler, prevent heavy objects from hitting the idler tube body.
5. In order to ensure the sealing performance and service performance of the Conveyor Belt Idler, it is forbidden to disassemble the roller at will.
Welding process editor broadcast 1. Select welding process according to the characteristics of materials Each type of welder corresponds to a type of material that cannot be effectively welder without first determining the material to be welder. for instance, Mig welding is suitable for alloy steel and non-ferrous metal welding Mag welding is suitable for low aluminum alloy welding Tig welding is suitable for stainless steel, aluminum, copper, titanium and their alloys (thickness control within 0.5~8mm). In addition, the electrode material should also be considered 2. Selection of protective gas The choice of protective gas is particularly important for Mag welding, where the use of reactive gases such as CO2 will affect the welding depth. For Mig, Tig and plasma welding, the use of inert gases such as argon and xenon can protect stainless steel, nickel alloy, titanium and titanium alloy, zirconium and other welds from oxidation at high temperatures. Extremely pure inert protective GASES are REQUIRED only for materials prone to high temperature oxidation, such as titanium, tantalum, zirconium and their alloys. The flow rate of the guard gas is also an important factor to consider, which depends on the size and capacity of the guard device. Care should also be taken to avoid the inclusion of inert gases that do not mix with surrounding gases or produce venturi effects. Laser welding usually requires an inert gas, usually helium, but argon, a mixture of gases, is often added to the gas, which can be used to weld certain metals. 3. There are many factors affecting safety in the welding work (such as welding splash, burn, explosion, spark, current, radiation, strong light burning, smoke......). Therefore, a protective facility (such as protective cover, ventilation room, etc.) should be placed around the equipment. If the protective facility is used unconditionally, personal protective equipment (such as protective clothing, welding gloves, protective shoes, goggles, etc.) can be used. In closed places, gas detectors should be equipped to prevent hypoxia. 17%). 4. Preparation before welding Preconditioning is very important for welding, by which the welding surface is treated to make it easy to weld. Many industries require leveling, correction and other pretreatment processes. Not only that, but also through the rust removal, protection and other processes to improve the welding quality of products. 5. Docking accuracy Accurate positioning of the butt plate is the prerequisite for accurate anchorage. Welding positioning requires high precision, and the position of weldment should be controlled at all times in the welding process. 6. External environmental control It is very important to control the air intake to prevent other liquids or particles from affecting the welding. When welding, install wind protection (to prevent external gas from entering during welding). 7. Welding speed monitoring Numerical control equipment must be used to ensure the stability of welding speed. To ensure the quality of the weld, it is necessary to control the uniform and stable electrode speed. If the welding speed is too fast, easy to lead to weld and have to rework. 8. Characteristics of electrode The appropriate dip Angle will vary for different welding processes, so make sure the Angle is appropriate during operation. The quality of the weld depends greatly on the current type and polarity. One of the advantages of Tig welding is its weld smooth and high penetration rate. 9. Maintenance of equipment Another important part of the welding work is the maintenance of the equipment, including regular replacement of aging parts, cleaning of scale on the inner wall of the nozzle, etc. 10. Select the welding process according to the thickness of the weldment Select the most appropriate welding process to get the best welding effect. There is no doubt that laser welding and Mig welding are two kinds of welding technology with the best welding effect. After welding, keep the torch at a proper Angle of inclination, otherwise it will lead to the escape of inert gas, solder joint surface adhesion and other consequences.
