Prater offers a wide range of sizing and separation solutions based on customers’ needs. We focus on vibratory (deck) screeners, rotary (centrifugal) sifters, and air classifiers.
Prater Particle Sizing & Separation Products
High capacity sifting and scalping at rates many times greater than conventional sifters with a similar screen area. The unique centrifugal force imparted by adjustable paddles, in combination with flexible mesh fabrics, greatly reduces binding problems when handling materials containing high fats/oils. A three-bearing design ensures smooth, vibration-free operation and long life.
Our mini-sifter is an easily assembled and disassembled rotary sifter that is completely versatile and vibration-free. It’s high throughput, safety interlocked features and heavy-duty design make the mini-sifter flexible enough for lab applications and rugged enough to meet small production requirements.
The Prater Vibratory Screener is a heavy-duty, mechanical machine that separates particles into multiple size fractions, removes oversized particles or foreign material, removes fines from a process stream, or segregates excess liquid from finished products.
The MAC forced vortex units process dry materials to an unmatched fineness and uniformity over a wide range of feed variations, either in closed-circuit with a conventional milling system or as independent “stand-alone” systems that incorporate feeder, fan and product collection equipment.
The Mini-split Air Classifiers were primarily developed for research “semi-tech” and small-scale production applications. An ideal choice for small workspaces, its low-noise capabilities reduce distractions while its compact size ensures efficient portability.
