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

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.

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. 

Why should we select bin above the conveying and screening equipment

Are you complaining the screening and conveying equipment you bought is not durable? Are you worried about equipment bearing capacity if you want to improve the production efficiency? Here we would like to give some tips for you:
No matter vibrating screen or belt conveyor, once they work with other corollary equipment, the joint parts are pretty crucial, the common one is hopper, it is not only because it can store material, but also can reduce the impact to screen mesh when feeding material, and increase the service life. In order to control the feeding rate of hopper uniformly, a electric or a manual gate valve can be added at the bottom of hopper, or a silo vibrator (we call it vibration hopper) to feed the material more uniform or vibratory feeder machine.
For example, one of our customers want a tilt screw conveyor, due to the small capacity, it needs to feed material to conveyor directly, we recommend placing a hopper on the screw conveyor in the purpose of storing material in order to ensure continuous working of screw conveyor and transmission efficiency of the screw conveyor.
During the use of conveying equipment, in order to improve the production efficiency of the conveying and screening equipment), it is necessary to put a hopper above the equipment. This will reduce the worker's labor intensity, the number of workers, the cost production line.

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.

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:

What Should You Pay Attention to About the Conveyor Belt with Large Angle?

Why you should pay attention to the belt conveyor with large angle? That almost because the heavily damaged by the belt which is under the overload.And then,this damaged will not only lead to the belt reversal,but cause more seriously accidient like belt broken,frame destroy.In order to avoid more damaged by the conveyor belt with large dip angle,it is necessary to learn the anti-reversal control methods.The following introduction would like to introduce the analysis detailedly.

Are you still using the capture device method to avoid this destory by the overload?You may find that it doesn't have a better real effect.Today we will show you a fresh way which you should pay attention so much.

With the anti-reversal control method,it’s better for you to adopt unidirectional rollers.

1.     When the belt goes up, the rollers will rotate accordingly

in this case, friction between upper belt and rollers is rolling friction.

2.     When the belt is breakage and upper belt goes downward slide, the rollers will not do reverse rotation

on this occasion, friction between upper belt and rollers is sliding friction. 

And then,in this way can it realize breaking.
