CHICAGO — Cumberland Engineering, a division of John Brown Plastics Machinery, introduced several new granulators at Plastics USA in Chicago.
The compact, 10-inch-by-18-inch model is an easily movable, soundproofed, low-speed granulator for beside-the-press granulation. It is engineered to be fed by hand, robot or conveyor. The granulator costs $7,900.
A 10-inch-by-12-inch model operates at a throughput of as much as 450 pounds per hour. Like the larger model, it grinds plastic from injection molding, blow molding and extrusion processes. The granulator features a multipurpose feed chute and a three-blade, scooped rotor with rotating end disks and a high-inertia flywheel. The machine costs $7,200.
``The 10 series fills a niche and runs at 5, 71/2 and 10 horsepower,'' said Jeff Denigris, marketing services manager for the South Attleboro, Mass., company. ``They fit where most granulators aren't anymore. Other companies have 10-by-12 [models], but there aren't many in the 10-by-18 size.''
In addition, John Brown is distributing Accrapak Systems Ltd.'s 900 Series strand pelletizers. The 4-, 6- and 8-inch machines offer easy, no-tool access to the cutting chamber for cleaning and maintenance. An overhung rotor design allows thorough cleaning, enabling rapid process changeover when colors or polymer grades are changed.
Accrapak is based in Warrington, England.
