Discrete Transport by Screw Conveyor Procedure
|
A Screw Conveyor (Discrete Flow) is used to represent an equipment resource used to host a conveying procedure with the objective to transport discrete entities by rotating a large screw. The procedure can be executed in a batch or continuous mode.
See Screw Conveyor (Bulk Flow): Equipment Tab.
In Calculate (Design Mode), the user specifies the Maximum Pipe Diameter and the system computes the Number of Units and the Pipe Diameter. The pipe cross sectional area (and consequently the pipe diameter) is calculated by dividing the operating throughput (m3/h) by the specific throughput (m3/h-m2). If the calculated pipe diameter exceeds the maximum, the system assumes multiple, identical units operating in parallel with a total cross sectional area equal to the calculated.
In User-Defined (Rating Mode), the user specifies the Number of Units and the Pipe Diameter, and the system calculates the specific throughput. The user always specifies the pipe length and the system always calculates the operating throughput. The bulk density of the conveyed material is used to convert the mass throughput into volumetric throughput.
Equipment purchase cost is based on the pipe diameter, the pipe length and material of construction. It is supplied by the built-in model assuming as material of construction CS.
