Stationary Screen

Overview

	Size / Design Variable	Mass Throughput
	Costing Variable (Built-in Model)	Mass Throughput
	Costing Variable (User-Defined Model)	Mass Throughput in kg/h
	Emissions Port	No
	Hosts	Screening in a Stationary Screen Procedure

A Stationary Screen is used to represent an equipment resource typically used to host a screening procedure with the objective to screen a stream in order to seperate solids larger than the specified mesh size. The procedure can be executed in a batch or continuous mode.

See Throughput: Equipment Tab.

Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Throughput and the system computes the Number of Units and the Rated Throughput. If the operating throughput exceeds the maximum throughput, then the system assumes multiple identical units operating in parallel with an operating throughput of less than the maximum.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units and the Rated Throughput. If the operating throughput exceeds the rated throughput of the step (which is equal to the rated throughput of each unit times the number of units), a warning message is displayed advising the user to increase the number of units or reduce the operating throughput.

Costing

The equipment purchase cost is calculated based on the mass throughput of the operation. A user-defined cost model based on mass througput may also be employed.
