HOW IT WORKS

More than ten years of in-use experience has demonstrated that GRADEX 2000 provides consistent, reliable performance with extremely low maintenance. When maintenance is required, all components are easily accessed and serviced. A typical cycle for a single sample is as follows:
	Configuration Operator selects pre-set test configuration and enters sample information.
	Operator loads samples Tests are ready to run and will require no more operator time. System loads sample into classification drum. Drum is arranged with up to 6 decks to provide required size and/or thickness separation.
	Separation Drum begins reciprocating motion to perform the first thickness and/or size classification. Material passes through the deck, is weighed and recorded in database. Drum automatically rotates to next largest deck and process is repeated and proceeds for all sides of drum.
	Record Generation Simple classification is completed, results are saved to database – can be sent to mill central computer system and printed automatically.
