Dig for the conveyor belt on the mine

1. Let me answer you: what's the difference between the conveyor belt used in the mine and in the mine? First of all, the belt is different, underground belt must be flame-retardant, other belts are easy to friction and fire when used underground, causing gas and coal st explosion accidents, causing heavy personnel and property losses. In addition, all kinds of equipment into the well should have coal safety signs (specified by the state).

2. Mine belt buckle or conveyor belt buckle is a thing, just a few names
the models of belt buckles are not unified, there are no relevant national standards, and the proction is relatively simple. As like as two peas, the same time, many manufacturers and dealers are changing their own models when they are sold.
for example, it should have been called Su, but it turned out that it was made by manufacturer a, so it was called a series, and so on
however, there are only a series of belt buckles, Su series, T series, V series and wolf tooth buckles, which are quite common
we are specialized in the proction of belt buckles. For details, please ask me, Carnegie Coulter belt buckles. But I didn't want to disrupt the market. I didn't change my name.

3. The surface of the conveyor belt is not smooth. Or the conveyor belt is too loose, or the conveyor belt shakes severely, causing things to fall down, the specific also need to check, hope to help you

If the conveyor belt is penetrated and torn, it is generally appropriate to use the convenient and quick cold vulcanized rubber repair agent for filling repair. Rubberloc, a commonly used rubber repair agent, is equipped with cleaning agent and primer in addition to the main agent and auxiliary agent. The whole set can not only ensure the repair efficiency, but also effectively ensure the continuous bonding effect after repair, so it can be tried

the field operation process is as follows:

1. lay the conveyor belt that needs to be repaired horizontally

2. cut the edge of the part to be repaired above the conveyor belt by 45 ° Angle cutting

3. the bottom of the conveyor belt is also 45 ° Angle cutting, but shorter than the top cutting

4. use a low speed angle grinder to grind the parts to be repaired

5. clean the grinding resie

6. use corrugated paper to completely seal the parts to be repaired from the bottom

7. use cleaning agent and brush to clean the area of conveyor belt to be repaired

8. after the cleaning agent is completely dried, the primer is painted on the area to be repaired to ensure that the area to be repaired is completely painted and the primer is dried

9. pour rubberloc curing agent into the main agent, and stir it fully for one minute with a stirring rod until it is completely fused

10. 

11. slowly pour the mixture into the area to be repaired until the surface is level with the conveyor belt

12. use scraper to smooth the repaired surface

13. after repair, it should be cured at 20 ℃ for at least one hour before starting up< br />

6. That is a conveyor belt buckle
Taizhou Tongjiang specializes in procing this kind of accessories, you can consult

7. Answer:
the first empty: static
the second empty: the same
the third empty: opposite
the direction of friction is opposite to the relative motion direction of the object. This "relative motion direction" refers to the direction in which the rice bag will move on the conveyor belt when there is no friction.
obviously, if there is no friction, the rice bag will slide, so friction is the obstacle to the slide, That is to say, if there is no friction in the second and third air, the rice bag will slide down. The function of friction is to prevent it from sliding down, so it will go up
