Wet and disperse powders with this new machine
The Coflow continuously operating powder wetting and dispersing machine (photo) is designed for a wide range of applications in various industries. In the Coflow, solids and liquid components are introduced in controlled quantities via solids dosing units or a liquid pump, and combined in a premixing zone with an oblique blade agitator. Fine dispersion then takes place using a rotor-stator system, whereby the stator can be designed with different slot widths depending on the application. An inducer installed between the premixing zone and the rotor-stator zone effectuates a pressure increase. This change in pressure causes the air brought in with the powder to be separated, resulting in a lower residual air content in the product, the company says. For the market launch at Achema, the Coflow is available in the size Coflow-4 for production with a total capacity of 6,000–13,500 kg/h. The size Coflow-3 is currently under development and, with a total capacity of 2,000–8,000 kg/h, is suitable for small-scale production and for use in pilot plants and technical training centers.
