Torque Capacities for screw conveyors
Conveyor pipes are listed in both Schedule 40s and 80s by their nominal pipe sizes. The pipe size selected should correspond to the standards listed for carbon steel pipe. Deviations from this standard are sometimes possible, in sectional conveyors, by the use of smaller pipe sizes (for economy) when the torque rating is adequate.

Screw Conveyor Engineering Guide  Horsepower Calculation
Total Shaft H.P. Calculation. TSHP = FHP + MHP* *Corrected if below 5 HP. Note: The actual motor horsepower required to drive the loaded conveyor system is dependent on the method used to reduce the speed the motor to the required speed of the conveyor. Drive losses must be taken into consideration when selecting the motor and drive equipment.

How to calculate motor drive torque for ball screws
May 18, 2016· For vertical applications, the torque required to cause back driving is important for determining whether the load will "fall" on its own, or if the screw assembly provides enough resistance to hold the load in place when no brake is applied. This article explains how to calculate the back driving torque.

conveyor torque calculation  Gear & Pulley engineering ...
Jan 09, 2009· From this I calculate the torque to be 6.2 kN and using an efficiency factor of 0.85 the power needed would be 3.0 kW. The driving force is provided by forcing the smooth surface of a grooved transmission belt, driven by the motor, against the surface of the chain block over a distance of 1.2mtr.

Conveyor Torque  Physics Forums
Nov 03, 2016· A company called the other day with a question about their conveyor. My company did not build the conveyor but did supply the gearbox. The conveyor is 8 feet long, and 4 feet wide, it is level and transports castings to the grinding department of a foundry. The motor they are using is a 4 pole 5HP ...

DESIGN AND SIZING OF SCREW FEEDERS
of the nominal torque of the motor in screw conveyors, and even lower in screw feeders. However, it is impossible to decrease the motor size as it will be unable to start. This is why the sizing done in accordance with the C.E.M.A. standards is quite reliable in screw conveyors; however, it is not quite so precise in screw feeders; so it is always

Calculate Horsepower For Inclined Screw Conveyors
Jan 09, 2008· Calculate Horsepower For Inclined Screw Conveyors Screw conveyors can be used to convey bulk materials at an inclined angle, but several areas of design should be examined first. Because of the incline of the screw, several conveying problems begin to occur. 1. The horsepower per unit of material increases

Screw Conveyor Torque  Engineering Guide
Torque is measured in inchlbs. for screw conveyor components. The torque rating of the drive shaft, coupling shafts, coupling bolts and conveyor screw must be able to withstand Full Motor Torque without failing. Every KWS screw conveyor is designed to this criteria with a minimum safety factor of 5 to 1.

How do you calculate force on a leadscrew?
Oct 08, 2010· Typically I like about 2x calculated torque. You always feel a lot better a little oversized than you do when the load doesn't move when you first fire it up. I would pick a middle ground efficiency like 17% and then make sure that whatever you are using to power the screw has 2x this torque capacity.

How to Calculate Load Torque & Motor Power
Mar 04, 2006· Hence, if conveyor in full load condition and stopped, the drive system can move the conveyor. They want me to give a proove that changing the Power of Motor won't solve this problem. So, I should know how to calculate the Motor Power and Torque? But for the belt density, I really don't know because they just give me an additional data:
