Based in the south-western suburb of Condell Park, Good Impressions retained Donaldson after outgrowing its old waste-handling system, with the printer operating to a “demanding” 24/6 schedule.
Donaldson project manager Dominique Ollitrault was charged with three objectives for the new system: it had to improve on waste management, improve on preventive maintenance, and meet EPA standards for dust emission.
The new system extracts paper trim from a saddle-stitcher, three folders, and two guillotines at the site, and is set to incorporate two new folders that are to be added to the floor at a later date.
The majority of paper strips and off-cuts on the Good Impressions production lines is collected by suction at operating points and carried through a ducting system suspended from the ceiling.
Donaldson opted to then deploy an air/paper separator as opposed to the more commonly used cyclone device.
“A separator was chosen over a cyclone because it has an inclined baffle plate, situated within an expansion chamber, to knock extracted product out of the air stream rather than relying on a cyclone’s geometry to cut a specific portion of product by centrifuge and internal vortex,” the company said.
After the separator, a Donaldson DCE Dalamatic DLM 1/5/15 dust collector takes over, which uses a reverse pulse jet cleaned fabric filter with a total filter area of 75m². Dust collected in the hopper is then discharged into an 80 litre bin.
The system also incorporates Visy Recycling as the end recipient of compacted raw material produced by the system.
“There is no valid reason why a resource as important as paper should be wasted in the modern, technological age,” said Good Impressions director Peter Edwards. “Hence we are involved in recycling a lot of the leftover product that goes through our production department.
“It is all expediently collected by our new off-cut handling system and Visy, as the end-recipient in our recycling loop, uses the waste to prepare recycled paper and cardboard.”
