Get better extraction results with the higher flake aspects available from the Szego Mill™
Simply swap rollers to go from fine round granules to wide ultrathin flakes.
Increase the 3D flexing reinforcement of plastics with Mica aspect ratios of 40-60.
The patent-pending rollers of the Szego Mill™ provides a larger surface area for oil and chemical extraction, even at finest grinds.
One of the important industrial growth areas relates to plastics. Reinforced plastics have found new, large-volume uses in diverse applications; automobile components and, indeed, car bodies belong to this group. To impart the best mechanical properties – tensile strength or flexural modulus, for example – the quality, both size and shape of the reinforcing filler materials is becoming more important. In the case of mica flakes, for example, a high aspect ratio (diameter-to-thickness) is desirable. The Szego Mill is a good candidate for such a grinding requirement. It allows considerable flexibility in use and can be operated so as to produce high aspect ratio flakes.
The flaky nature of its products gives the Szego mill a potential advantage over other grinding equipment in mineral matter liberation. The stability of coal-oil, coal-water or other slurries is enhanced due to the decreased settling rate of such flakes. Throughput of the existing small Szego mills (22 cm I.D.) is high, ranging between 200-500 kg/h of coal for a product median size of 15-30µm, from a feed size of -1/4".
The initial boulders have been transformed into large flakes due to the rolling action inside the mill. A wide variety of product specifications can be met by appropriate combination of design choices and operating conditions.
