The common roller conveyor drum material surface mainly includes carbon steel galvanized, stainless steel, rubber lagging and so on. These materials play their own advantages in different applications.
The surface of the carbon steel galvanized drum has good corrosion resistance and anti-wear performance, and is suitable for wet or corrosive gas environments. After the carbon steel is galvanized, it can form a protective film, which can effectively prevent corrosion and prolong the service life of the drum.
Stainless steel rollers are widely used in food, medicine and other industries with high requirements for hygiene conditions because of their excellent corrosion resistance, heat resistance and wear resistance. The surface of the stainless steel drum is usually polished to ensure cleanliness and hygiene during product handling.
The surface of the lagging drum is made by wrapping the surface of the drum with a rubber material that has good elasticity, abrasion resistance and shock absorption. The lagging roller is especially suitable for conveying heavy loads or when there is a need to protect the surface of the goods, which can effectively reduce the damage to the goods and reduce the noise at the same time.
When selecting the drum material and surface treatment, it is necessary to consider the conveying environment, cargo characteristics, frequency of use and other factors to ensure the efficient and stable operation of the drum conveyor system. Reasonable material selection and surface treatment can not only improve the service life of the drum, but also meet the specific needs of different industries for conveying equipment.
The transmission drum is divided into three kinds from the production material: steel plate coil welding, cast steel and cast iron. In terms of structural type, there are three types: assembly spoke plate type, spoke type, and integral spoke plate type. In addition, the surface of the drum has smooth, rubber, cast rubber and other types, among which the spoked cast rubber drum with steel plate welding is the most widely used. When the power is small, the bandwidth is small and the environment is dry, the smooth drum with bare leakage can be used, the rubber-covered roller has a large friction coefficient, good anti-slip and drainage, but it is directional, and the cast rubber roller is used for two-way running conveyors.
