screening machines

Gradex Chip Classifiers are the original fully automated chip classifiers. The machine features PC-controls, automated test reporting, and the ability to operate in the lab or in the wood yard. With a proven track record of trouble-free, reliable operation in mills throughout the world, the Gradex Chip Classifier is ideal for controlling chip quality. This machine allows for close monitoring of purchased chips and chips per performance.

Particle Size Analyser How it Works


Configuration The operator selects a preset test configuration and enters the sample information.

Operator Loads Samples The tests are then ready to run and will not require additional operator time. The system loads the sample into the classification drum. The drum is arranged with up to five decks to provide the required size and/or thickness separation.

Separation The drum then begins a reciprocating motion to perform the first thickness and/or size classification. Material passes through the deck and is then weighed and recorded in database. The drum automatically rotates to the next largest deck, and the process is repeated and proceeds for all sides of the drum.

Dry Particle Sizing Installation Installation


Computer Control Cabinet The GRADEX Chip Classifier control system is housed in a free-standing console that includes dual fans to keep the machine dust-free. The console serves as an operator workstation that houses the PC monitor, keyboard, and printer.

Gradex Software Windows-based software provides easy operation.

Auto Time Operator can set fixed cycle times for each separation or choose to operate AutoTime. Using AutoTime, continuous weight readings are taken and the test is ended when a preset rate of change is reached.

Record Generation Classification data presented in tabular or graphic formats.

Six Separations Utilise all five surfaces of the Gradex Chip Classifier to provide six separations. Each surface can be arranged with a perforated plate or a rod deck for size and/or thickness separations.

Classification Individual samples of 2500g each can be fed manually or use AutoFeed.

Autofeed and Autodischarge Allows operators to load up to six samples with only one setup. AutoDischarge is optional.
