Step 1 : define the requirement. Define the capacity required for the screw conveyor. The design of the screw must reach a capacity equal or greater than this value. Example : the requirement for a screw conveying sugar is 3500 kg/h. Step 2 : calculate the capacity of the screw conveyor. Assume a diameter D.

For applications that may require the "unorthodox" width greater than the length, type of conveyor, modular belt conveyors will achieve that feat much easier. Since they are non-metallic, easy to clean, and porous to gas and liquids, modular belt conveyors can be applied in: Food handling. Fluid handling.

Belt Speed (BS): The calculator computes the belt speed in feet per second. However, this can be automatically converted to other velocity units via the pull-down menu. The Math. The formula for the speed of the belt is: BS = (D •π • R)/(2π) = ½•D•RPM. where: BS is the Belt Speed; D is the diameter of the pulley

What is the formula for conveyor belt length? The formula for calculating conveyor belt length is: Belt Length = (2 * π * Radius of Pulley) + (Distance between Pulleys) + (Number of Turns * π * Diameter of Pulley). How much speed is 7000 RPM? To convert RPM to linear speed, you need to know the diameter of the rotating object.
