Häny HCM 2500 mixer

Häny HCM 2500 is the largest colloidal mixer (high shear mixer) in the HCM series and is particularly suitable for producing suspensions of water, cement, finely ground binder, bentonite and other materials. Mixing takes place in a robust mixing tank with a conical bottom, where the high-speed TMP 60 mixing pump creates high turbulence and gives a very good mixing result. According to Häny, a robust mixing tank combined with highly wear-resistant materials in the mixing pump gives a long service life and reliable operation.

With a usable capacity of 2500 litres, the HCM 2500 produces around 40 m³ of suspension per hour at a water/cement ratio of 1, and the circulation capacity is 4800 l/min. The liquid temperature can be up to 40 °C. Switching between mixing and transfer is controlled by pneumatic pinch valves, and the shaft seal is lubricated automatically. The mixer has load cells for automatic dosing of water and dry components, with a DN80/200 water inlet and three DN200 inlets for dry components. A cleaning opening (manhole) makes cleaning easy.

The electric motor delivers 45 kW at 50 Hz (53 kW at 60 Hz) and runs on 3x 400/460 V, with a nominal current of 70.0/82.4 A and a speed of 1475/1770 min⁻¹. The machine weighs approx. 2500 kg and measures 2585 x 2220 x 1893 mm (L×W×H). The HCM 2500 can be used stand-alone or combined with a Häny HRW agitator and grout pump. According to Häny, the HCM series is characterised by very good mixing quality, high capacity and low wear.
