As a rule, the specified belt width must be wide enough to handle the material lump size. The specification of belt width will depend upon the material lump size. Additionally, the service life of a belt conveyor running at an extremely high speed may be shortened considerably due to excessive vibration. Higher belt speed usually translates to a higher horsepower requirement. Suitable conveyor belt speed typically ranges between 2.5 m/s and 3.5 m/s. A = Conveyor’s belt cross-sectional areaīelt speed should be specified such that it does not cause spillage of the raw material being conveyed.The magnitude of the belt speed can be determined using: The first step in the design of a belt conveyor with a specified conveyor capacity is to determine the speed and width of the belt. Conveyor belt dimension, capacity and speed These will serve as a guide for the design of the conveyor belt to be made.Ī typical preset design specification for the design of a belt conveyor system. Common design specifications set during the early design stages include the volume flow rate of bulk material, conveyor capacity, transporting distance and the material lump size. Surcharge angle describes the angle that the surface of the material makes with the horizontal when it is at rest on a moving conveyor belt.īefore proceeding to design a conveyor belt system, engineers must set a design specification.Belts are troughed to allow the conveyor load and to transport materials. Troughing angle describes the angle the belt forms on the carrying side while running over idler rollers. For instance, the lump size of a steel grit is its diameter. Lump size describes the maximum dimensions of the bulk material being conveyed.It is measured in ton per hour (TPH) or kg/hr. Capacity (C) describes the rate at which the bulk material is being conveyed by the belt.However, before proceeding to the design of a conveyor belt, some key terms must be understood. It will take into account the belt sizing, speed, capacity and motor requirements. This article presents the basic steps for designing a belt conveyor system.
