Minimum Pulley Diameter For Conveyor Belt

conveyor belts ? determination of minimum pulley diameters,this international standard establishes a method of calculating minimum pulley diameters for conveyor belts. it applies to belts made of rubber or plastics with textile or metal carcasses, of different carcass thickness and different carcass materials, operating at any anticipated belt tension up to, but not exceeding, the maximum belt tension (rmbt)..minimum pulley diameter – phoenix conveyor belt systems gmbh,the pulley diameters in a belt conveyor system depend on the design, on strains and on the type of splice of the conveyor belt. for determining the minimum diameters, the following pulley groups will be distinguished: group a: drive pulley and other pulleys in the range of higher belt tensions; group b: deflection pulleys in the range of lower belt tensions; group c: snub pulleys (change in belt moving direction = 30°).conveyor pulley selection guide,most conveyor belt manufacturers recommended the minimum pulley diameter specification for conveyor belting based on the individual belt characteristics such as the belt material, construction and profiles. excessive shaft deflection occurs when shaft diameter is improperly sized for the demands of.conveyor belt speed and pulley diameter -,b. pulley diameters are normally selected for the belt construction. number of fabric plies and carcass construction dictate the minimum diameter. for steel cord belt the minimum pulley diameter is dictated by the steel cord wire strand size, cord construction, belt tension and belt.
