What is the impact roller?
Impact Roller is one of the support and counseling elements used in flat and trough conveyors systems. A specific function of the impact cylinder is to rent additional support of the conveyor at transmission and loading points, where the belt is exposed to considerable impact stress. Although generally similar to other elements of the cylinder, the impact cylinder is equipped with a central member of a reduced diameter and stronger, grooved rubber lining. The stronger lining and grooved surface offer excellent durability compared to conventional cylinders. Impact Rollers can be arranged in standard, solid gacing frames, or suspended in Garland arrangements depending on the configurations of the belt. This roller arrangement ensures that the belt is supported and run straight. They can also be configured to allow the belt to deviate laterally around the bends while maintaining the corresponding load area. Impact Rollers serve a specific purpose help to absorb an intense impact on the belt in loading and transmission BOde.
conveyors carrying large aggregates such as raw coal and iron ore are constantly battered at the point where the belt is loaded or one belt is released to another. These repeated impacts can seriously wear a conveyor and eventually lead to a belt failure. The rows of impact cylinders are located at these points in such a way as to pad the large part of the force and prevent accelerated wear. The frequency of rows of impact cylinders at the load point is usually higher than the normal guide rollers along its length.
Conventional idle and guide rollers would not allow the same degree of protection as the impact cylinder, because they usually have large diameter shells with thin rubber backpack. Impact Rollers differs in design in that they have a much smaller core of the shell and a much stronger Rubber lining. This lining is usually designed as a set of concentric rings that form a grooved surface to cylinderi
cylinder spindles are flattened in the same way as normal on idle, allowing the cylinder to be inserted into standard fixed images. This gives logistics flexibility affecting cylinders because they can be used on standard trough frames. If it requires the configuration of the belt, the rollers on the Garland style can also be suspended. Typical gaps of impact cylinders rarely exceed 17 inches (450 mm) to allow maximum belt support.
