Jul 09, 2018 Sizing a screw conveyor can be very easy, when you know a few of the basics. Of course, there are many screw conveyor applications which add elements to the calculation set that require some experience and expertise but for most traditional applications the process is well defined and resources are available in every screw conveyor manufacturer’s catalog.
Get Price Sent MessageCapacity of Screw Conveyor: The capacity of a screw conveyor depends on the screw diameter, screw pitch, speed of the screw and the loading efficiency of the cross sectional area of the screw. The capacity of a screw conveyor with a continuous screw: Q = V. Ï. Q = 60. (Ï€/4).D 2.S.n.ψ.Ï.C. Where, Q = capacity of a screw conveyor

Read MoreThe capacity of a Screw Conveyor should be defined in terms of cubic feet per hour. It is also important to determine the maximum capacity the conveyor will be required to handle. This capacity is very often stated in terms of tons or pounds per hour. However, the material to be handled often varies in
Read MoreThe initial step in engineering a Screw Conveyor is to analyze the physical characteristics of the material and the rate at which it is to be handled. The capacity of a Screw Conveyor should be defined in terms of cubic feet per hour. It is also important to deter-mine the maximum capacity the conveyor will be required to handle.
Read MoreCompared with other transportation equipment, screw conveyor with the machine section size small, reliable sealing performance is good, smooth operation, screw and feeding tube adopts new structure of subsection and demountable facilitate transport clean and safe operation, convenient maintenance, etc.
Read MoreScrew conveyors vary in size from 75 to 400 mm in diameter and from less than 1 m to more than 30 m in length (Hemad, Mohammad and Mohammad, 2010; Owen and Cleary, 2009; Labiak and Hines, 1999). ...
Read MoreS = Screw Conveyor Speed. The torque rating of the drive shaft, coupling shafts, coupling bolts and conveyor screw must be greater than Full Motor Torque for proper design. A 12-inch diameter screw conveyor was selected for the example. The minimum standard shaft size for a 12-inch diameter screw conveyor is 2-inch diameter.

Read MoreThe actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing 333 cubic feet per hour.
Read MoreLarger-capacity screw conveyors typically are installed horizontally or at small slopes and are usually of the U-tube configuration, which permits inspection of the entire screw in place, if needed. CEMA (1980) describes design procedures. Because of previously cited corn damage and energy use problems, screw conveyors seldom convey corn in ...
