The flat-edge spiral-screw conveyor design (photo) features a broad, flat edge that minimizes the potential for aeration to add volume to low-bulk-density materials during transfer. Offered with the company’s Spiralfeeder flexible-screw conveyor, the new design is suitable for transferring cake mixes, starches, mica, fly ash, carbon black and other dry, low-bulk-density powders, pellets, flakes and granules. Consistent, uniform conveying at high throughputs is assured without clumping, clogs or compaction. Customized based on the material properties, target throughput rate and other factors, the flat-edge spiral design is machined from 100% stainless steel as standard and is available with a polished surface finish for sanitary processing. — Automated Flexible Conveyor, Inc., Clifton, N.J.
