Tri-Kneader Mixer TriVolution® B&P Littleford’s TriVolution® Compounder is a very distinct mixing machine that reciprocates the process screw 3 times for every 1 revolution. The flights interact with pins in the barrel much in the same way a continuous kneader does. High Performance & Efficiency The TriVolution® offers excellent dispersive and distributive mixing without damaging critical ingredients by its innovative mixing mechanism. Its controlled shear with enhanced material exposure is also well adapted for devolatilization and reactive processing. The TriVolution® mixer also establishes the highest standard of performance in shear sensitive mixing applications while achieving the highest energy efficiency. Recognizing the compounding industry's need for improved mixing technology, B&P Littleford has achieved what could have been considered impossible with Continuous Kneaders and Twin Screws. The B&P Littleford TriVolution® compounder is uniquely designed and has set a new industry standard by mixing higher quality material, faster and cheaper. Reciprocating Continuous Kneaders In Continuous Kneaders, three-rows of screw flights are available to interact with three pins located in the barrel wall. The flights of the screw are interrupted and, as the screw rotates, it also oscillates creating a series of shearing, stretching and folding actions (similar to taffy or dough kneading) that leads to excellent mixing of the product at low shear. The nature of the mixing action is relatively low-shear and thereby more suited toward thermoplastics and thermoset materials which are sensitive to heat and shear stresses.
