Vertical Screw Mixer

A rotating vertical screw lifts material from the bottom cone to the top of the batch and lets it fall back. The whole volume circulates in 30–60 seconds, which is why the machine blends thoroughly with roughly a third of the power a horizontal ribbon mixer of the same capacity would need.

Batch capacity0.25 – 2.5 t (0.5 – 5 m³)
Mixing time3 – 12 min depending on model
Motor3 – 15 kW, 380 V / 50 Hz, 3-phase
Contact materialCarbon steel (painted) or 304 / 316L stainless
Heating optionJacketed body, thermal oil or steam
DischargeManual slide gate or pneumatic flap valve
Surface finishMirror polish for stainless, ≤ 0.8 µm Ra on request

Features

Why this design instead of a ribbon mixer

  • Roughly 1/3 the installed power of a horizontal mixer at the same batch size.
  • No dead corners — the cone bottom discharges almost completely, so recipe carry-over between batches stays low.
  • Compact footprint: a 2 m³ unit fits under a 3.5 m ceiling, which matters in existing buildings.
  • Single moving assembly. Bearings and the screw flight are the only wear parts, both kept in stock.
  • Stainless execution with polished internal surfaces for feed additive and premix duty.
  • Heated jacket version for molasses coating and fat addition without cold spots.
Typical Applications

Where it is installed

  • Powder compound feed lines, before screening and bagging.
  • Premix and additive blending where batch accuracy matters more than throughput.
  • Fertilizer and soil-conditioner blending.
  • Chemical powder and mineral filler mixing.
  • On-farm feed preparation at 1–5 t/day.
Model Range

Standard sizes

Larger and intermediate sizes are built to order; capacity can also be matched to an existing conveyor or silo outlet height.
