Notice! Prohibit the following things during the operation of mobile belt conveyor

During the operation of mobile belt conveyor, if we operate it in the wrong way, it may lead to short service life, conveyor damage, even hurt the operator, please see the following things which are prohibited during the operation of the mobile belt conveyor:
1. Prohibit turning on the switch before making sure all nuts and bolts are tighten.
We usually disassemble the mobile belt conveyor during transport process. Customer needs to assemble it on site. If the nuts and bolts are loose, they may fall off during operating, thus, it will be a great potential safety hazard.
2. Prohibit changing the conveyor head direction before shutting down the switch.
Please shut down the switch first if when you want to change the conveyor head direction, or it will be easy to hurt the operator.
3. Prohibit moving the conveyor before shutting the switch
Mobile belt conveyor is a kind of light- weight conveyor, it can be moved anywhere, however, please shut down the switch first before moving it to ensure the safety of the operator.
4. Prohibit standing under the conveyor.
Please note, prohibit standing under the conveyor no matter operate the conveyor or not.

Portable Belt Conveyor

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. 

Coal Mine Belt Conveyor:Installation Safety Technical Measures and Matters

1. Please pave the conveyor belt in strict accordance with the belt central line that production department gives. Belt should be paved to make sure flat, straight, and below rollers complete and effective, sweeper should be conformed to the requirements, lining plate of head and tail frame, as well as the guardrail should be complete and reliable.
2. Belt conveyor parts should be transported according to the order of tail frame, middle frame and the head frame, after transporting to the designated location, please put them away as per the transportation order along the roadway.
3. Belt conveyor should be installed according to the order of head frame, middle frame, the tail frame, central line of each pulley belt conveyor should be in a straight line.
4. Belt conveyor parts should meet the requirements, the anchor bolt should be fixed and tighten reliably.
5.All sorts of protection device of belt (Anti-frog protection, speed protection, temperature protection, automatic water spray protection if overheat, deflection protection) after the installation is complete, please test each protection device to make sure they are and sensitive working in good condition. 
6. Please set up a bridge for walking where people go cross the belt conveyor frequently. 
7.The electric switch protection device must be completed which should be sensitive and reliable ,the protection setting values must conform to the requirements, and keep them from water and rain, there should be enough space for walking and repairing, cable should be placed neatly and in order, communication signal should be in good condition, light and sound should be clear and reliable, control signal device should be complete, sensitive and reliable, explosion-proof lighting lamps and lanterns should be installed.
8. Both the head and tail section of belt conveyor must be equipped with two fire extinguishers and fire sand box which is not less than 0.2 m3.
9. Sweeper installation must meet the production needs. Sweeper and conveyor belt surface must contact well to ensure appropriate tightness and uniform contact, please also make sure both the head and tail section must be equipped with a sweeper.
10. In the section that the roadway changes to slope where belt waves easily, to ensure the belt frame transition smoothly, you can by adjust the supporting leg of conveyor.
11.After completing all the installation ,ensure all rollers and the belt are connected in good condition, then you can commissioning the conveyor.

Highly recommend operation direction graph of steel wirerope in portable belt conveyor

Mobile belt conveyor is a kind of convenient loading equipment with high efficiency. It can move through wheels, at the same time, the lifting height can be adjusted through the lifting device. It is widely used in warehouse, ports, wharf, station, coal yard, construction sites, etc.

The belt width and length can be custom-made according to different requirements. However, we usually need to disassemble the mobile belt conveyor during transportation as the packaging volume is larger. Customer will assemble the mobile belt conveyor in local when they receive it. However, the steel wire rope and conveyor belt installation direction is very important in the whole assembly process. Proper installation direction of the steel wire rope and conveyor belt will affect the lifting and running ability directly, in order to show the installation direction clearly, the following drawing drawn by our engineer is for your reference specially:

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.
