These conveyors are built for performing heavy duty jobs. Since they lift such heavy objects, a powerful motor and strong belt components are required. A screw conveyor may use either driven or gravity moderns, depending on the design. The rollers and sleeves can be made of either PVC, plastic, or galvanized steel. Plastic and PVC can only be used for conveying large objects that are fairly light. Galvanized steel is very strong and capable rolling items that weigh several tons.
Light conveyors are made for carrying light items. Steel is used as the primary material, but plastic and aluminum can also be used for minor components. These conveyors can either be very small or very large, depending on the objects moved, but the items are always light. Medium conveyors are made from strong metal because they carry a heavier load. They have a larger diameter compared to their lighter counterparts, usually measuring between 2 ½ inches to 5 inches. Heavy duty roller use thick tubes made from solid iron. Some of these conveyors are capable of carrying items that weigh several tons and measure several feet in diameter.
Conveyor rollers are specialized equipment, which means it is almost impossible to build a "one size fits all" design. When a company wants to purchase a conveyor, they will usually give the manufacture the size and weight limits so it can be custom built. These machines are very intricate so it is almost impossible to repair or build one without specialized help. Repairing can even be difficult for conveyor companies because each roller set may have an individual size and shape. A typical conveyor roller will consist of shafts, bearings, sprockets, screws, a large chain, wire mesh, and belt. The conveyor belt is usually made out of rubber, but there are also plastic varieties. When a company purchases a conveyor roller, they are purchasing it to hold their specific products. Since each company has a different sized product, the conveyors need to be custom sized to handle the load of each item.
