continental conveyor ltd. has supplied world-class material-handling solutions for decades. its wide portfolio includes vital components like belt conveyor pulleys. a major benefit of working with the continental crew is its considerable ability to design and fabricate custom belt conveyor pulleys that meet almost any client need.
the diameter of the pulley must be designed such that it does not place undue stress on the belt. the length of a belt conveyor in metres is the length from the centre of pulley parallel to belt line. belt length is dependent on both the pulley diameters and centre distances. capacity is the product of speed and belt cross sectional area.
drive arrangement: in belt conveyors the driving power is transmitted to the belt by the driving pulley which is rotated by an electric motor. the basic mechanism of transmission of power from the pulley to the belt is based on the theory of friction drive. the fundamental equation for a belt conveyor drive is given by: (the euler’s equation)
a motorized pulley is simply a drum motor in which the outer shell rotates around a stationary shaft. the revolving member serves as a traction pulley, gripping and driving the conveyor belt.
wing conveyor belt pulleys available in standard duty and mine duty. beater pulley. custom made beater conveyer belt pulleys for high angle corrugated sidewall conveyors. spiral wing. rotations of the pulley automatically starts the self-cleaning action, discharging foreign material to the side of the conveyor.
the tail pulley is located at the end point of the belt conveyor. it comes with either a flat face or a slatted profile (wing pulley), which cleans the belt by allowing material to fall between the support members. 3.bend pulley. 4.snub pulley. the bend pulley is used for changing the direction of the belt.
crowned pulleys — which option is right for you? the purpose of a crowned pulley (or tapered pulley) is to assist with belt tracking. in most operating conditions, a belt will follow the path of highest tension. so, it makes sense to have the diameter of the pulley larger in the center than at the edges. most often, conveyor systems that use

common calculations for proper design belt length . when the head and tail pulley are the same size: l=(d+d)/2 x 3.1416+2c when one pulley is larger than the other pulley: l=(d+d)/2 x 3.1416+2c+(d-d) 2 /4c. belt speed. expressed in feet per minute (fpm) s=d x rpm x .2618 x 1.021. belt load
conveyor pulleys, conveyor belt pulley, stainless steel conveyor pulley design there are many elements to consider during the design of a conveyor pulley. the most important however is the design of the shafts. other elements that need to be considered are the pulley diameter, the . inquire now; engineering & dimensions conveyor pulleys
tb = 1.37*f*l*g* [2*mi+ (2*mb + mm)*cos (δ)] + (h*g*mm)…….eqn.1.1. where, tb is in newton. f = coefficient of friction. l = conveyor length in meters. conveyor length is approximately half of the total belt length. g = acceleration due to gravity = 9.81 m/sec2. mi = load due to the idlers in kg/m.
