By Justin Wheeler, CFPHS, C-Series/Bent Axis Project Manager, Hydraulic Pump Div., Parker Hannifin. Bent-axis piston motors feature pistons placed at an angle to the drive shaft, rotating the shaft as fluid enters the motor. The ideal in hydraulic system design is to match overall efficiencies to the application performance expectation.

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. Trough fill level is the percentage of available cross sectional area of the screw diameter. Why 30%-45% trough loading?

Step 1 : calculate the mass flow rate. The compressor is to deliver 2000 Nm3/h of air. Normal conditions are here defined as 101325 Pa and 0°c [1], at this pressure gas ideality is mostly verified thus the specific gravity is PM/RT/1000 = 1.294 kg/m3. This gives a mass flowrate of 2000*1.294 = 2587 kg/h.

If the conveyor is 100 feet long the HP required is about 1.4 HP to move the material. To run the basic empty conveyor, babbet bearing take about 2.9 HP and with ball bearings it takes 1.45 HP. So with ball bearings my conveyor would take about 2.85 HP (1.4 material + 1.45 conveyor).
