The roller is an important part of the belt conveyor. There are many types and large quantities, which can support the weight of the conveyor belt and the material. It accounts for 35% of the total cost of a belt conveyor and generates more than 70% of the resistance, so the quality of the roller is particularly important.
The roller with a long-life, fully-sealed, dust-proof and waterproof structure designed and produced by Yilun has the characteristics of high precision, low rotation resistance, low operating noise, and long life (lifetime greater than 50,000 hours).
It is widely used in all transportation places such as mines, power plants, steel plants, stone materials plants, cement plants, coal washing plants, salt plants, alkali plants, fertilizer plants, docks and so on.
1. The roller tube adopts the special welded tube for roller, which has small radial, good ovality and uniform wall thickness.
2. The shaft is made of ultra-high precision cold drawn round steel, which has good corrosion resistance and high strength.
3.The bearings are high-precision and low-noise double-sealed bearings and KAC3 bearings for coal mines, which have the effects of wear resistance, corrosion resistance, static electricity and dust.
4. The bearing seat is made of high-quality cold-rolled steel plate, with uniform wall thickness, high precision and no burrs.
5.The roller seal is a double labyrinth seal of the national standard, which is dustproof, waterproof, anti-corrosion, wear-resistant, cold-resistant, anti-static and other advantages.
