About this machine

This AMK Aachen is a used mixer and blender — sometimes referred to as a sigma blade mixer or kneader — designed for the intensive mixing, blending, and kneading of viscous, paste-like, or doughy materials. AMK Aachen is a well-established German manufacturer with a long history of producing heavy-duty mixing and kneading machinery for industries including rubber, plastics, food processing, chemicals, and pharmaceuticals. This particular machine is a Z-blade mixer configured as a mixtruder, meaning it combines the mixing action of contra-rotating Z-shaped blades with a screw discharge system that continuously or batch-extrudes the processed material from the trough — a practical arrangement that reduces manual handling and speeds up discharge.

The working volume of the trough is 20 litres, with internal trough dimensions of 355 × 355 × 420 mm. The machine is built entirely in stainless steel, making it suitable for food-grade, pharmaceutical, or chemically aggressive applications. The trough is fitted with a cover and a jacket, allowing temperature control of the batch through heating or cooling media circulated through the jacket wall — an important feature when processing materials that are sensitive to, or require, specific processing temperatures.

The drive arrangement is double-geared, providing the torque characteristics appropriate for handling dense or high-viscosity materials. The Z blades operate at an arm speed of 33 rpm. Adjustable packing glands are fitted, allowing the shaft seals to be maintained and tightened over time to minimise leakage around the blade shafts — a detail that speaks to practical long-term serviceability. The screw discharge (mixtruder) function is included as standard on this configuration.

The machine is mounted on a fabricated frame and has a floor footprint of 1.3 × 1.6 metres with a total installed height of 1.6 metres. It is located in Barneveld, Netherlands. The type plate is missing, so the precise model designation is unconfirmed, but all physical specifications listed above were recorded by the seller directly from the machine.
