Technical Specifications (Nolin Milling Catalog)
OEM Nolin Milling fabrication from Dickens, Iowa. Sizes are outside-diameter (round) or outside width (square) unless noted. Select diameter/size, gauge, lining, and finish on this page; price, weight, and freight cube update with the option set.
Flow retarder. Internal 1/2" baffles (7 ga carbon, 7 ga AR on wear points) create a moving pile that cuts grain velocity. Install on approximately 10 ft intervals on steep or long runs. Welding-sleeve models drop into existing round spout. Vertical-drop retarders are for true vertical legs; 45° cushion turnouts are used when a vertical spout must kick out. Catalog capacity guidelines use ~70 BPH per square inch of interior area for 8" and larger spouts on clean corn, soybeans, or wheat at 40° or greater. Target grain velocity under 1,750 FPM to limit kernel damage and premature wear (see Nolin grain-velocity chart). A 100 ft spout at 45° typically needs 2 retarders; at 60° about 3; at 85° about 6 (Nolin grain-damage chart). Approximate shipping size for an 8"–12" inline unit: 24–30" long × (size + 6") square.
Construction. Laser-cut and plasma-cut carbon, galvanized, or 304 stainless from 14 ga through 1/4" plate. Seams welded; flanges punched to Nolin national-standard patterns unless a custom form is submitted. Catalog capacity guidelines use ~70 BPH per square inch of interior area for 8" and larger spouts on clean corn, soybeans, or wheat at 40° or greater. Target grain velocity under 1,750 FPM to limit kernel damage and premature wear (see Nolin grain-velocity chart).
Available option families across the Nolin line include diameter/size (commonly 4"–24", some gates to 36"), gauge (14, 12, 10, 7 ga, 1/4" wall), lining (none, 7 ga AR, 1/4" AR, blue urethane, orange urethane, ceramic-chip urethane, ceramic tile), and finish (primed gray, galvanized, stainless).

Capacities assume clean, dry whole grain at 40° or steeper. Wet corn should be spouted at 45° minimum. Lining and fittings reduce capacity. Guidelines only — confirm with the factory for your application.
