Twin Shaft
Mixers

Mix more. Faster. Forever.

AJAX Twin-Shaft Mixers deliver maximum output for ready-mix concrete and large infrastructure pours. Two counter-rotating horizontal shafts create three-dimensional mixing zones that homogenise even the toughest aggregates and stiffest mixes — at cycle times as short as 30 seconds.

Engineering Highlights

Built for the
real worksite.

Counter-Rotating Shafts

Two horizontal shafts spin opposite directions, creating overlapping mixing zones.

Short Mixing Cycles

Achieves uniform mix in 30-45 seconds — twice the throughput of pan or drum mixers.

Heavy-Duty Construction

Reinforced trough and shafts designed for 50,000+ hour service life.

Sealed Bearings

Multi-stage labyrinth seals keep cement slurry out of bearings — 5-year service intervals.

Quick-Open Discharge

Full-width hydraulic gate empties the mixer in under 5 seconds.

Modular Liner Design

Bolt-on tub liners and replaceable mixing arms. Refurbishment in hours, not days.
