Stop carrying seed up ladders. Screw elevators lift grain and oilseed into roaster and press hoppers continuously at 500 kg/h through a sealed 140 mm tube — inclined models from 2 to 5 meters, vertical models for tight floors, and assist-feeding versions with hopper for second-stage feeding. Galvanized or 304 stainless.
Every press stop for hand-feeding costs throughput, and ladder work with seed sacks is the most common injury point in small mills. A screw elevator turns feeding into a closed, continuous process: seed augers up the sealed tube dust-free and lands exactly in the hopper.
Three configurations cover mill layouts: inclined (2–5 m) for the classic floor-to-hopper run, vertical (2–3 m) where floor space is tight, and assist-feeding versions with their own inlet hopper for second-stage transfer between machines. Motor sizes run 1.1–2.2 kW with the length.
| Type | Lengths | Motor | Output | Tube |
|---|---|---|---|---|
| Inclined | 2 / 2.5 / 3 / 3.5 / 4 / 5 m | 1.1–2.2 kW | 500 kg/h | Φ140 mm |
| Vertical | 2 / 2.5 / 3 m | 1.1–1.5 kW | 500 kg/h | Φ140 mm |
| Assist-feeding (hopper) | 2 / 2.5 / 3 m | 1.5 kW | 500 kg/h | Φ140 mm |
Seed travels inside the closed tube — no spills, no dust cloud over the workshop, no contamination.
Inclined, vertical and hopper-fed assist models solve floor-to-hopper, tight-corner and machine-to-machine transfers.
Standard galvanized tube for seed duty; 304 stainless option where food-grade washdown is required.
Built per meter to your layout — heights between standard sizes are a standard order, not a special.
500 kg/h on 1.1–2.2 kW; the elevator pays its power bill in saved labor within weeks.
Measure hopper inlet height and the floor distance available for the incline; as a rule of thumb an inclined elevator needs roughly 1.5× the lift height in floor length. Send both numbers and we size it exactly.
Inclined moves material most gently and cheaply when floor space allows. Vertical models exist precisely for tight floors — same output from a smaller footprint at slightly higher wear.
Grains, pellets and most free-flowing granular materials are fine. Sticky or fibrous materials (wet cake, hulls in bulk) need different conveying — ask us about screw conveyors instead.
Galvanized handles dry seed duty for years at lower cost. Choose 304 stainless when regulations, washdown cleaning or corrosive conditions demand it.
Grease the bearings on schedule and check the screw flighting for wear annually — that is essentially the whole list. No filters, no belts to tension.
