How To Calculate Conveyor Belt Cleaner Drag and Required Power

How do we calculate power required to overcome this drag? Continuing with this example, if we say that the conveyor belt has a belt speed of 300 feet per minute (fpm), we can calculate required power as follows. Required Power = 300 pounds of drag x 300 fpm of belt speed. Required Power = 90,000 foot pounds per minute (ft-lbs/min).

How To Calculate Conveyor Skirtboard Drag and Required Power

0.276 x 15′ x (4″)2 = 0.276 x 15 x 16 = 66 lbs. CEMA gives a frictional coefficient of 0.01 for wood chips. To calculate the drag for this material, use the equation: 0.01 x 15′ x (4″)2 = 0.01 x 15 x 16 = 2.4 lbs. Notice that the frictional coefficient of iron ore is 27.6 times higher than that for wood chips.
