What are the reasons for the damage of the conveyor idler?

1. The sealing performance of the conveyor idler is poor, and the bearing is polluted by water or dust: In order to minimize the rotation resistance of the conveyor idler, the labyrinth seal structure is basically adopted.

1. After the rotation resistance increases, the circumference of the pipe body is quickly ground through;

2. A hole is grinded in the pipe body when the bearing is stuck.


2. Pollution of the conveyor idlers caused by thin mud pollutants: When the water in the coal mine is heavy, the slime adhering to the conveyor belt will fall onto the supports and conveyor idler shafts on both ends of the conveyor idlers.


3. The bearing positions at both ends of the conveyor idler are out of tolerance, and the bearings are forcibly rotated and damaged early.


4. Material's severe abrasion on the tube body of the conveyor idler: In coking plants, sintering or pelletizing plants in the iron and steel industry, steel slag and wet furnace slag are transported, hard and sharp materials adhere to the conveyor belt, which will wear the tube body of the conveyor idler tube. It's fast.


5. Severe corrosion of the conveyor idler tube body: the coal wears little to the conveyor idler and conveyor belt.

6. Rapid damage of the conveyor idler on the self-aligning bracket: The original function of the self-aligning bracket is to adjust the center when the material on the conveyor belt is eccentrically loaded.


7. The V-shaped forward tilting support conveyor idler is damaged faster: the support conveyor idler installed on the V-shaped forward tilting support always runs in friction with the conveyor belt. Although the forward tilt angle is small, according to practical observations, The wear of the pipe body is about twice that of the conveyor idler on the fixed bracket, and the service life is naturally about 1 times lower.


8. There are two reasons for the short-term damage of the buffer conveyor idler:

A. Due to the large dust at the blanking point, the buffer conveyor idler is easily polluted and damaged when the sealing performance of the buffer conveyor idler is poor;

B. The cushion rubber ring is basically made of recycled rubber, not only has poor elasticity, but also has poor wear resistance, tear resistance, and aging resistance. The impact force is small, and the service life is only about 1 year. When the impact force is large, It will break and fall off within ten days, causing serious damage to the conveyor belt.
