A conveyor belt is a tool that is essentially created for moving and transporting material from one specific point to another. This consists of a structure that supports it where two rollers are mounted, one in the head and one in the tail where the belt flows, these rollers are stretched so that the surface remains without hollows, in case the belt has to carry very heavy materials it is possible to use additional rollers placed in the middle between the ends, or it is even possible to adopt a system without a belt using only the rollers. The belt moves thanks to a powerful motor applied on one or more rollers.
