The Ball & Jewell BP18 Shred-Buster is a floor-standing plastic granulator designed for size reduction of plastic scrap and runners. Manufactured by Ball & Jewell — a division of Sterling Inc. of Milwaukee, Wisconsin — the BP18 is a mid-range granulator built for integration into injection molding, extrusion, and blow molding production lines, as well as standalone regrind operations. It accepts material through a top hopper or a side feed port and discharges ground regrind through a bottom collection port.

Applications

Plastic granulators like the BP18 Shred-Buster are standard size-reduction equipment in plastics manufacturing and recycling operations. They are used to grind sprues, runners, rejected parts, film, and scrap plastic back into regrind pellets or flake that can be blended back into the production process — reducing material waste and raw material cost. The BP18's dual feed configuration (top hopper and side port) makes it suited for both at-press use alongside injection molding machines and for central regrind rooms processing mixed plastic scrap. Ball & Jewell granulators were a widely used brand in U.S. plastics processing facilities from the 1970s through the 1990s, and spare parts and screens remain available through Sterling aftermarket suppliers. This size class (5 HP, open-throat feed) is typically used for processing smaller plastic parts, thin-wall components, and film rather than heavy-wall profiles or large structural parts.
