What are idlers?
What are the classifications of belt conveyor idlers?
Operation and maintenance?
Idlers is an important part of belt conveyor, which has a variety of types. How much do you know about Todd? The following will introduce you to the idler of belt conveyor and its classification.
What are idlers?
Peralatan conveyor idlers is an important part of supporting the conveyor belt and materials. It has many kinds and large quantities, and it is also one of the components with the largest number of belt conveyors.
The role of the idler is to support the belt and reduce belt resistance. The quality of the idler directly affects the service life of the conveyor. A good idler of the belt conveyor can reduce the friction between the belt and the idler, reduce the loss, and extend the service life of the belt conveyor.
The idler of belt conveyor is different from the unpowered drum for material transportation, although its composition and appearance are similar. However, the carrying capacity of the idler of the belt conveyor is large, and there are corresponding restrictions on the speed. It is widely used in mining, chemical industry, building materials, cement, coal and other industries.
What are the classifications of belt conveyor idlers?
The idler of belt conveyor can be divided into upper groove idler, buffer idler, transition idler, return idler and centering idler according to their functions.
The following is a description of each type of idler.
Trough idler
Trough idlers are widely used in open air and dusty environment due to their diversity. When using troughed idlers, the following advantages can be obtained:
- Strong wear resistance
- l Trough idler is fully sealed
- l Long service life
- l Low operation cost
Penyangga Idler
The buffer idler is mainly used for buffering. It is used at the receiving place of belt conveyor to mitigate the impact of blanking on the conveyor belt, and is widely used in corrosive environments.
There are 35 ° and 45 ° buffer idlers, which shall be selected appropriately. When canvas conveyor belt is selected, only 35 ° groove buffer idlers can be selected.
When using the 45 degree groove type buffer idler, you can use the 45 degree groove type idler in the section where the guide chute is not impacted by materials to reduce the impact of the conveyor belt and extend the service life of the conveyor belt.
The buffer idler has the following advantages:
- l Wear resistance and corrosion resistance
- l Antistatic
- l Small rotation inertia
Transition idler
Generally, transition section shall be set for conveyors with large capacity, long distance, large belt tension and important conveyor.
Return idler
Return idler, also called parallel lower idler, is used to support the conveyor belt. It is also the most used lower idler.
Centering idler
The aligning idler includes ordinary aligning idler, friction aligning idler and tapered aligning idler. The centering idler is used to automatically correct the excessive deviation of the conveyor belt during operation to ensure the normal operation of the conveyor.
Operation and maintenance
- Before using the idler, carefully check the appearance for serious collision and damage. The rotating idler should rotate flexibly without jamming.
- The installation distance of the idler shall be determined by scientific calculation according to the type of logistics and the characteristic traffic volume of the conveyor, so as to avoid too sparse or too dense installation.
- Pemalas harus dipasang untuk menghindari gesekan timbal balik.
- As the number of belt conveyor idlers is the largest, the maintenance of belt conveyor idlers is particularly important.
- The idler of belt conveyor shall be kept in a dry environment during use, and the damaged idler shall be replaced in time.
- Clean the materials attached to the idler in time to keep the roller surface clean.
- During the use of the idler, it is forbidden to strike the idler tube with heavy objects.
- When replacing the bearing, the opening of the bearing cage must be outward. After the bearing is installed into the idler, the proper clearance shall be maintained and it shall not be crushed.
Select the appropriate idler to reduce the friction between the belt and idler, reduce the loss, and extend the service life of the belt conveyor.
