The features of the Wiener Ball Mill Generation 7 The most effective refiner of its kind
This proven concept, with a track record of more 40 years, is based on a slow rotating shaft and high energy impact. The most significant difference with our competitors: we don't apply additional force on the balls, we just use the natural gravity flow. The result is less wear and tear and hence less iron in the product, which makes this ball mill a sustainable one
Maintenance reduction program
Increase your production stability and quality and obtain at the same time a fat greasing reduction of 80% , by introducing smart technical features and machine design. Interference on the machine is reduced to a minimum. By installing for example the automatic fat greasing system, informing the operator when the fat greasing system should be replaced. This ensures a continuous well-greased system.
Pillow Plate Technology
