GRANULATORS
Take a big bite out of your rejects with new granulators and shredders built for large parts. From heavy purgings to thermoformed sheets to automotive bumpers, these heavy-duty machines tackle size-reduction challenges with
relentless efficiency.
Throughput and quality of granulate are the key differentiating points among the various types of size reduction equipment available for large, bulky or dense plastic pieces. Traditional granulators have the benefit of high throughput, while shredders or shredder/granulator combinations tend to operate more quietly on less energy but don't have high throughput levels.
When dealing with post-consumer scrap, throughput is a critical factor in profitability, explains Mike Cyr, vice-president, sales at Rotogran International Inc. "The key to a high throughput is to have a large screen area," says Cyr, "and a large diameter cutting circle."
Rotogran recently sold a giant granulator that will be used by a recycler in the Toronto area to process post-consumer scrap from Toronto's curbside collection program. Rotogran has guaranteed this WO 4465-36-- HD granulator will process 8000 Ib/hr. of post-- consumer scrap, and reduce it to granulate that passes a 3/8 in. screen. The machine has an infeed opening of 44 in. x 65 in. with a 36 in. cutting circle. It weighs about 20 tons, says Cyr.
Cumberland's 3200 Series of granulators are suitable for post-consumer products, heavy extruder purgings, sheet, pipe and blow molded parts for automotive, appliance and furniture applications. The 3200 Series is available in three sizes. All have a 36 in. cutting circle, hydraulic hopper/cradle, 200 to 400 hp motors and throughput rates up to 12,000 Ib./hr.
MEET THE MULTI-TASKING GRANULATOR
To take full advantage of the size and power of a large granulator, Granutec's Multi-Task Granulation System Model TFG3648 has a convertible hopper and rear feed chute for simultaneous feeding of parts to achieve maximum throughput.
The convertible hopper design uses a transition insert to accommodate changes in part size...
