The milling system features a new rotor-stator principle: a ring-shaped stator with internal teeth slides over a high-speed rotor with external teeth, making sure each product is always milled to the correct size. The rotor revolves in the stator around its own axis at speeds that can peak at up to 50 metres per second. The user can choose between coarse, standard or cross-toothed tools and an individually adjustable milling gap, to ensure optimal processing whatever the formulation, the company states.

The shearing, rebound and crushing forces acting on the product can be precisely controlled because the rotor speed is continuously variable. The mill is available in several different versions – from laboratory models with a product throughput of 100 litres an hour to industrial types capable of handling up to 40,000 litres, depending on the application.

The engineers responsible for designing the mill paid particular attention to eliminating all dead spaces such as gaps, corners or slots from the interior. Residues from the production process are thus prevented from accumulating, significantly reducing the risk of contamination of subsequent batches.

The Romaco Fryma Koruma technology will be on show at the Interphex trade fair in New York (USA) from April 23 to 25, 2013 (Stand 3033).
