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.

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.
