Reasons for rivet free connection wear equipment

1. The belt is off track. Roller packing wear and abnormal operation of idlers affect belt deviation. The idlers at the high point of belt deviation have great stress, and the idlers at long hours simply wear and thin until cracking.

2, belt return section adhesion slag. Cleaner blade wear, not close to the belt surface, ash and slag viscosity increase, high water content will constitute the belt surface with slag.

3, ash slag moisture content is high. The filter element and drain pipe of buffer slag bin are blocked, the drain pipe of gate plate is blocked, and the filter element is not washed back in time after slag discharge, which will lead to too much water in ash slag belt.

4, buffer slag bin ash straight row. The slag out of the slag dredger without a constant dehydration, directly transported to the dehydration bin by the tube belt machine, will constitute more water content of the slag, the increase of the tube belt machine no-load hours, accelerate the wear of the roller.

5, rivetless connection bearing quality. Some idler working surface cleaning, due to bearing quality doubt will also constitute a transition insensitive or card astringency, and then appear wear.

6, the sealing function of the rivetless connection is poor. Water slag accumulation into the roller bearing, forming a smooth or poor transition sensitivity and wear.

7, thin pulp type of ash wear roller. Sometimes the slurry slag from the dredge machine is simply adhered to the tape and falls onto the bracket and roller shaft at both ends of the roller. On the one hand, it will wear the roller body, on the other hand, it will agglomerate and form a card.

8. Wear and tear of the roller body by ash and slag with larger granularity. Sometimes the slag machine out of the larger particles of ash, adhere to the tape, hard and sharp material on the roller body wear quickly.

9. Ash and slag overflow at the mouth of tubular belt bag. Roller group roller wear, belt transport material is too much, will constitute the belt bag mouth is not tight, belt attack a certain resonance, the bag mouth ash overflow causes other roller wear faster.
