5 conveyor pulley selection guide pulley/core diameter – the outside diameter of the cylindrical body of a conveyor pulley, without coating. finish diameter – the outside diameter of a coated pulley (core diameter + 2 times the coating/wrap thickness). face width – the length of a pulley’s cylindrical body.this area is intended to act as the contact surface for the conveyor belt.
introduction of screw conveyor • screw conveyors are widely used for transporting and/or elevating particulates at controlled and steady rates. • they are used in many bulk material applications in industries ranging from industrial minerals, agriculture (grains), pharmaceuticals, chemicals, pigments, plastics, cement, sand, salt and food processing.
the kws screw conveyor engineering guide will provide assistance in the design of a screw conveyor or system, yielding optimum performance and efficiency . primary considerations for the selection of a screw conveyor are: 1 . type and condition of the bulk material to be conveyed including maximum particle size and specific bulk density 2 .
you can get a more detailed view of your abrasion situation with the following calculations: screw tip speed (ft/min) = screw dia. x rpm x π / 12. trough surface speed (ft/min) = screw pitch x rpm x (1 - % loss*) / 12. * percentage loss due to modified flights, reverse pitch paddles, incline, etc.
the 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.
calculation of conveyor speedthe maximum recommended capacity for each screw diameter is listed in the capacity the capacity factor for cut and folded flights with 30-percent trough loading is 3 .75 .therefore: sc = 1 .50 x 3 .75 x 333 ft 3 /hr sc = 1,873 ft 3 /hrthe selection capacity will be used to select the proper screw conveyor diameter and speed from the capacity table . with a recommended trough
