Why will Belt Conveyor Pulley Wear?

Belt conveyor is a kind of common conveyor equipment, often used in a variety of material transportation with large throughput, stable performance. In the process of using, pulley may occur wearing, this phenomenon is caused by two reasons:
One reason is that the design gap between roller bracket and pulley is too small, at the same time, building foundation hole vertical distance is less than the pulley support distance.In the process of belt running, overlarge belt tension will result in the change of its traction.Return accretion has not been cleared up, which will form accumulation debris and occur rubber friction.For design factors,as the space between pulley stents and pulley is too small, and the base hole of the vertical distance is less than the pulley support distance, it is not easy to handle timely, which is the main cause of pulley rubber lining wear.
Work environment factor is the second reason leads to rubber lining equipment damage phenomenon.

Belt Conveyor Safety Operation Regulation

Belt conveyor is a kind of continuous conveying equipment. Can be widely used for quarry, coal, steel, chemical and other kinds of industries. Operating the belt conveyor safety, not only can make sure the safety of the operator, but also can longer the service life of the belt conveyor. PK machinery will introduce the safety operation regulation of the belt conveyor:

1. The belt conveyor should start without load and should not feed material until it operating regularly. Forbidden feed the material before starting.
2. Fixed belt conveyor should be installed on fixed foundation. Before the mobile belt conveyor operating officially, wheels should be holdback through triangular wedge or brake. To avoid move during operating, there should be an 1 meter channel between each machine if multi-set belt conveyor operating parallelly.
3. Before using the belt conveyor, we must check whether all the moving parts, belt buckles and bearing device is normal or not; whether the protective equipment is completely or not. Belt tensioning degree should be adjusted to the appropriate level before starting.
4. Forbidden stand on the conveyor belt.
5. If multiply sets belt conveyor connection with each other one by one, we should start the one in discharge end first, then start the other sets according to their order. You can feed the material once all of the equipment operating normally.

Follow the Right Operation of Fixed Belt Conveyor, Otherwise Accident will Occur

1.Fixed belt conveyor should be fixed in accordance with the specified installation methods on the foundation;
2.Before start-up ,please check all the moving parts of belt conveyor, such as if belt buckles and bearing device is normal, if the protective device is complete, if the belt tensioning condition is adjusted properly before start-up;
3. Fixed belt conveyor should no-load start up, only when operation is normal, can you feed the material, feed material before starting up the conveyor is not allowed;
4. when units of belt conveyor operate in series, please start from the discharged end in order, only when the operation is normal ,can you feed the material;

 

5. When belt deviation appeared in the operation of the belt conveyor, please stop the conveyor and adjust timely, so as not to wear edges and increase the load;
6. The work environment and material temperature should not be higher than 50℃ and lower than -10 ℃;
7. The conveyor must not convey people, and people is not allowed to stand under the conveyor;
8. Stop feeding material before stopping the conveyor, only after stored materials are discharged completely you can stop the conveyor;
9. Belt conveyor motor must be in good insulation;
10.Do not use your hand to pull the belt in order to avoid accidents when belt slips.

Failure Analysis of Belt Conveyor Components

In the process of operation, failure of belt conveyor is inevitable, here PK Machinery will analyze the cause of belt conveyor failure.
1.Belt doesn’t rotate
After start-up of the belt conveyor motor, the belt of drive pulley idles and slips, belt can’t rotate, this failure is caused by insufficient belt tension, improper adjustment of tension device, overlong length, overloading start-up, coal piled in the tail part of belt conveyor.
2. Belt is easy to break
It is due to the large belt tension loose joint, poor quality of belt buckle, belt using for a long time, poor maintenance of belt, the solution is to tighten tension device, lower the tension ,change the new belt in time and strengthen the maintenance quality.
3. Reducer occurs abnormal sound.
The reason is due to the larger gap caused by serious wear of bearing and gear or screw is too loose, the solution is to replace the bearing, adjust the gap and repair or replace the whole reducer.
4.Reducer heats up too fast.
The reason is because of too much oil, poor heat dissipation performance, speed reducer is buried in coal pile, the solution is to adjust oil amount and remove the coal.

5.Reducer oil leakage.
The reason is due to the damage of sealing ring, the connecting surface of reducer is not uneven, the bolt is too loose, the solution is to replace the sealing ring, tighten the connecting surface and the bearing cap bolts.

 

6.Roller doesn’t rotate.
It is because of the damage of roller bearing, when coal powder enters into the roller sealing ring on both sides, it will be blocked and not rotate which makes the roller bend due to the large stress. The solution is replacement roller, reduce the height of discharging point and the landing point, or use the shock-proof roller at the landing point.

How to #select suitable #belt for #corrugated #sidewall #conveyor?

Corrugated sidewall belt is used for pulling and carrying purposes for corrugated sidewall conveyor. It consists of a baseband, corrugated sidewall and baffle. The corrugated sidewall connects with both sides of baseband while the baffle connects with both side of corrugated wall accordingly to a certain space. 1. Baseband
The baseband appearance of corrugated sidewall belt is the same with ordinary belt ,but its lateral stiffness is greater than ordinary belt. Usually corrugated sidewall belt adopts special belt as its baseband, the tensile materials (core layer) can be divided into four kinds: cotton canvas, nylon canvas, polyester canvas and steel wire. 2. Corrugated sidewall
This series of products using S-type of corrugated sidewall.

3. Baffle
a) This series of product is recommended to use type T, type TS (B), type TC, type TCS (B) and type C baffles.
b) Type T and type TS (B) baffles are only suitable for conveyor angle β≤40 ° while type TC and type TCS (B) and type C of baffles are suitable for conveyors with any transmission angle.
c) Type C baffle is suitable for conveying viscous materials. On the other hand, if the conveying angle and material density are greater, then type TCS (b) baffle should be used.
d) The spacing between baffles is integral multiple of waveform of the corrugated sidewall. The spacing between baffles (TS) and height (H) are related to conveying angle β.
