When it comes to a conveyor belt system, rollers represent a significant portion of the overall investment required for its implementation. It is therefore of paramount importance to make a careful selection of the rollers to be installed and to verify that they are suitable for the belt's use, made with precise workmanship and selected materials. Only in this way is it possible to achieve the high quality of the roller that guarantees an operational life suitable for the plant, thus avoiding unnecessary and economically damaging plant downtime.
The choice of roller type should take into account the following factors:
Abrasive materials such as clays, granites, and iron minerals may necessitate the selection of heavier-duty roller series, favoring a larger diameter of the roller tube as this results in less contact between the roller surface and the belt itself. For plants transporting corrosive materials such as salts, chemicals, etc., it's imperative to choose protected rollers or rollers constructed with appropriate materials that are resistant to these substances over time. Rollers can be made of steel, coated with multiple layers of paint according to specific cycles, or coated with rubber or other anti-corrosive materials. Alternatively, they can be entirely constructed from corrosion-resistant plastic materials. Environmental conditions with high levels of dust (transporting cement, limestone, ashes) require the use of rollers from series with sealing systems that offer the highest degree of possible protection.
