Impact idler is one of the conveyor idler, which are making for rubber rings and steel roller.China has many impact idler manufacturers. The most important thing of idler is produce technology. The surface of impact idler is consists of a series cold-drilling rubber and locking ring. In addition, the locking ring is used for fixing rubber rings, and then welded together with iron pipe.
According to the application, the impact idler will be installed in the bottom section of conveyor, to reduce the belt blow and extend belt life. Impact idler is the main buffer. So it the necessary part of conveyor system. It is a kind of roller which is developed for the corrosive environment such as coal washery, chemical plant and coking chemical plant, because of 10 times more resilient than normal metal. The advantage of impact idler are corrosion resistance, anti-static and light weight. The weight of idler is light and the rotation is small. Roller is special polymer material light weight, weight is one 7 of the steel, made of this material roller, nearly half of the weight is common roller, rotary inertia small, small friction between roller and belt. It is widely used in mining. According to the standard of China, There are 4 types for 500mm-1400mm belt, it is φ89mm, φ108mm, φ133mm, φ159mm. But in a foreign country, the diameter of the rollers are different, it will increase according to the width of belt. China impact idler manufacturers are provide the OEM service.
How to choose and install? For choose: there are several matters need attention when you choose the impact idler: 1. roller eccentricity quantity: within the diameter run-out by the state, it can keep the conveyor running smooth. Otherwise, it will cause resonance, pollution and waste materials. The more conveyor at a high speed, the more you need to keep a small diameter run-out and stable. 2. roller flexibility: it can let the belt moved smoothly, and keep the production. 3. roller dustproof performance: it is depend on the bearing, advanced sealing system played the important roles, double sealed, ball bearing design, external Shield deters impurities from entering the bearing housing, triple Labyrinth Seal design is grease filled and offers an additional level of protection from contaminants impacting the bearing, all these will improve the bearing’s life. 4. waterproof performance 5. supporting roller bearing performance 6. rollers shock resistance. All these things will influence the idlers’ life. For install: the first thing is you need improve the quantity of rollers, the other is regular inspection ( replace damaged rollers timely).
