For a quick estimate of fpm simply follow the formula below: (cpm) / (# containers per foot) = fpm For example if you can fit 5 containers within one foot of conveyor and you know your cpm is 100: (100 cpm) / (5 cont/ft) = 20 fpm Don't want to do the math? Try our online calculator to figure out your conveyor speed in feet per minute.

Thus TSHP is calculated as follows: TSHP = 0.256 + 1.320 = 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.

L = Length of screw conveyor in meter Power due to inclination: Pst This power requirement will be the product of the mass flow rate by the height H and the acceleration due to gravity g. Pst = Im.H.g / 3600 = Im.H / 367 H should be taken positive for ascending screws and will be negative for descending screws.

The diameter is a function of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. To ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are running at 30%-45% trough fill level.

Compute the linear speed after 5 s. Answer: Acceleration a = 5 rad s -2 Radius r = 3 m Time t = 5 s The angular velocity is given by ω = ω 0 + at = 0 + 5 (5) = 25 rads -1 The linear speed is given by v = r ω = 3 m ×× 25 rad s -1 v= 75 m/s. Example 2: Compute the linear speed of a body moving at 50 rpm in a circular path having a radius of 2 m?
