Rotogran International Inc.

We design single pass, high capacity granulators capable of reprocessing plastic scrap into valuable regrind regardless of its original shape or size. Rotogran’s combination of an offset cutting chamber with a tangential feed throat, and an open rotor design, force scrap directly into the cutting circle eliminating material bounce while dramatically increasing your overall production rate.

Within the recycling industry our WO & TN Series units are the most popular with 26 or 36-inch cutting circles and motor horsepower ranging from 100 to 500. Hopper openings range from 36 to 72 inches wide by 30 to 44 inches deep. Production (throughput) is rated from 3000 to 10000 lbs/hr. Rotogran also offers loading conveyors, metal detectors, permanent magnets, blower/cyclone evacuation systems, dust separators, rotary air-locks, surge bins, and box dumpers.

Twin solid steel flywheels provide the inertia required to collapse and cut through large bulky parts without losing rotor speed. The double sissor cutting design of our chamber creates a side to side cutting action utilizing the entire chamber to spread the workload evenly. Easily replaceable wear plates strategically placed within the cutting chamber walls saves time and costly repairs when dealing with dirt and abrasive materials. Hydraulically assisted hopper and screen operation dramatically decrease down time for routine blade changes and maintenance.

As oil prices rise so does the value of plastic regrind. Rotogran recognizes an emerging trend of recyclers demanding rugged solidly built equipment that will withstand the extremely harsh conditions they face. They are not interested in fancy bells and whistles, but only in quality, reliability, and production. Recyclers seem to prefer the durability and value of older refurbished equipment rather than risk failure associated with inexpensive offshore products. The ability to source parts and quickly return to production when a disaster strikes is crucial to their survival.
