Read MoreHi im designing an auger inside a tube for crushing fruit and im trying to work out the forces acting on it.The design is 16cm long and 5 cm diameter and it turns at 88rpm.I think it needs a torque of 6 nm.Its throughput needs to be 1kg a hour.I was trying to calculate the horziontal and shear forces if possible thanks.
Read MoreIn inclined screw conveyor, as we increase the angle of conveyor from ground, its capacity decreases.Here inclination factor comes in play.Say, if angle of inclination is 15, inclination factor is 0.75.It means, conveyor capacity will be 0.75times of horizontal conveyor capacity.
