Processing machines and mills from Romaco FrymaKoruma grind, mix and homogenize according to the rotor-stator principle.
At the centre of this year’s presentation by Romaco FrymaKoruma at ACHEMA 2009 is the CoBall® MS 18 annular gap bead mill. This inline mill is used for the finest grinding of chemical and pharmaceutical products down to the nano range. Products can be changed quickly, easily and with minimal product loss.
FrymaKoruma is also presenting the Dinex 200 vacuum process machine for the manufacturing of liquids and semi-solids. The machine is equipped with a powerful homogenizer designed according to the rotor-stator principle. The product optionally circulates through an internal or external recirculation line, which facilitates variable batch sizes.
These products can be seen from 11 to 15 May 2009 at ACHEMA in Frankfurt am Main, Germany, in hall 6.0 at booth B40-C41.
FrymaKoruma CoBall-Mill MS 18: finest grinding down to the nano range
The CoBall MS 18 annular gap bead mill from Romaco FrymaKoruma is used for the finest grinding and dispersing of liquid to highly viscous products. The inline mill has a product throughput of 10l/hr to 80l/hr and achieves particle sizes down to the nano range. The system is designed according to the rotor-stator principle and is equipped with a conical grinding gap, which is 80% filled with grinding beads. All milling tools are available in designs with different materials and coatings, which makes it possible to process individual raw materials in a product-specific way.
With a width of 6.5mm to 13mm, the conical mill gap is relatively narrow, which allows a significantly high shear energy deposit of 6MW to 8MW per cubic metre of mill space volume. The rapidly rotating rotor powerfully accelerates the grinding beads, so that the shear force on the product continually increases. This leads to progressive pulverization of the particles. The energy generated is regulated through the largest possible heat exchange surfaces on the rotor and stator elements. Optimal cooling is essential, particularly in processing temperature-sensitive products. The grinding beads remain in the interior of the mill during milling and the subsequent cleaning process. During product discharge, they are separated from the product flow through a separation gap and passed back to the product input area through special return conduits.
CoBall-Mill technology generates an accurately controllable flow configuration of the grinding chamber. Each product element takes the same route through the milling gap and is subjected to the same grinding mechanisms. Particular attention has been paid to the elimination of dead space in the design of the mill interior. Aseptic O-ring seals additionally prevent the formation of concealed deposits and thus contamination of subsequent batches. Fully-automatic ‘cleaning in place’ (CIP) is significantly accelerated thanks to the smooth surfaces of the components. The FrymaKoruma CoBall-Mill MS 18 thus offers absolute process security and combines the highest product quality with increased productivity.
