	Hosts	Grinding (Discrete Flow) Procedure

A Grinder (Discrete Flow) is used to represent an equipment resource typically used to host grinding procedure with a main objective to grind discrete entities into smaller size bulk solids. The procedure can be executed in a batch or continuous mode.

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

Equipment purchase cost is based on the mass throughput and material of construction. It is supplied by the built-in model assuming as material of construction CS.
