Continuous Sand Mixers:
Single-Arm, Double-Arm & Twin-Shaft Durchlaufmischer
From compact jobbing foundries to 60+ t/h series lines. Axmann designs, builds and installs continuous foundry sand mixers for furan, phenolic urethane and alkaline phenolic binder systems, engineered in Germany since 1909.

What is a Continuous Sand Mixer?
The Heart of Every No-Bake Moulding Line
A continuous sand mixer, also called a Durchlaufmischer or resin sand mixer, is the machine at the centre of every no-bake and chemically bonded sand moulding line. Unlike batch or turbine mixers, a continuous arm mixer meters silica sand through a trough while injecting liquid binder and catalyst directly into the sand stream. The sand exits the discharge already activated, ready to flow into the flask around the pattern. The process never stops: while one mould is being filled, the next batch of sand is already mixing. That continuous flow is why foundries producing large castings, complex geometries or high-volume series runs choose arm mixers over the alternatives.
Axmann manufactures the full range of continuous foundry sand mixers, single-arm, double-arm and twin-shaft, from 5 up to 60+ tonnes per hour. Every mixer is configured for the specific binder chemistry (furan resin / Furanharz, phenolic urethane, alkaline phenolic / Alphaset), sand temperature range, and throughput of the installation. Integrated binder and catalyst dosing stations, sand conditioning, and line-wide control come from one supplier, engineered as one system. From single-shift jobbing foundries to 24/7 series production, the same Axmann mixer family scales without reinventing the process.
Configurations
Four Continuous Mixer Configurations
Every foundry is different. The right arm count and shaft geometry depends on casting weight, cycle time, factory layout and binder chemistry.
1
Single-Arm Continuous Mixer
Einwellen-Durchlaufmischer. 5 to 15 t/h. The workhorse for compact jobbing foundries. Smaller footprint, lower investment, ideal for medium-sized castings and single-shift operation.
2
Double-Arm Continuous Mixer
Doppelarm-Durchlaufmischer. 15 to 30 t/h. Extended reach serves two patterns in parallel or one large pattern faster. Standard choice for mid-capacity foundries scaling up from single-arm.
3
Twin-Shaft Continuous Mixer
Doppelwellen-Durchlaufmischer. 30 to 60+ t/h. Two counter-rotating shafts deliver the highest throughput and the most aggressive binder dispersion, for series production and very large castings.
4
Mobile & Overhead Mixer
Travelling on overhead rails or floor-level tracks, the mobile configuration serves multiple flask stations with one mixer, ideal for floor-moulding layouts and very large one-off castings that cannot come to the mixer.

Axmann Continuous Mixers in the Field
Why Axmann Mixers?
Built for Foundries That Run Without Stopping
Continuous Flow, Zero Batch Interruptions
Sand is activated on demand at the discharge, no waiting on a batch cycle, no mixer sitting idle between moulds. Pattern turnaround becomes the only constraint.
Precise Binder Metering
Mass-flow dosing holds binder and catalyst ratios within ±1%, the foundation of consistent mould strength, predictable cure time and repeatable casting quality.
Binder Flexibility
Furan, phenolic urethane, alkaline phenolic, the same mixer family runs every common chemically bonded sand system. Switch chemistry without changing your capital equipment.
Scale Flexibility, 5 to 60+ t/h
One jobbing shop, one series line, one giant one-off, the same mixer architecture scales across the entire casting industry.
Closed-Loop Ready
Axmann mixers integrate directly with mechanical and thermal sand reclamation, delivering over 90% reuse rates. Lower new-sand cost. Lower disposal cost. Lower carbon.
Built to Last Decades
Wear-lined trough. Heavy-duty drive. Serviceable dosing heads. Axmann mixers installed in the 1980s are still running today, the benchmark for German foundry engineering.
