B&P Process Equipment and Systems LLC has introduced the TriVolution Kneader, a reciprocating kneader that incorporates the benefits of a twin-screw extruder — an innovation B&P calls Tri-Kneader.
Larry Slovin, president and CEO of B&P, said engineers at the company in
B&P historically focused on the twin-screw extruder, which is the dominant machine for the compounding market. The Ko-Kneader took a back seat, company officials said. But B&P said the Tri-Kneader combines the high-torque, high-shear capabilities of the twin-screw extruder with the “finesse compounding capability” of the Ko-Kneader, coupled with its high free volume and short length to diameter.
With the TriVolution, B&P has achieved multiple oscillations per revolution. With each stroke of the screw shaft, the mixing flights of the screw interface with stationary pins lining the barrel wall.
The Tri-Kneader can be run in a very-low-temperature mixing configuration, according to B&P, and can be configured as a high-shear-intensity mixer.
