Highly efficient, outstandingly hygienic and extremely versatile – just three of many good reasons to choose FrymaKoruma mills. Used in laboratories and on production lines in many industries, FrymaKoruma mills are suited to a vast range of applications. The portfolio includes toothed colloid, corundum stone and perforated disc mills. And since the milling tools are interchangeable, all mills can be used for a wide range of purposes – precisely adaptable to the products to be processed.
Products are loaded via a hopper that can also be fitted with a feed screw, or via a pump. The milling zone is sealed by an innovative, single or double-acting mechanical seal, with no dead space. All product contact surfaces are very easily cleaned with no need for dismantling (CIP). Thanks to optimized residue discharge and thorough washing of all static seals during the cleaning process, compliance with the highest hygiene standards (GMP, DIN EN 1672) is assured. In all industrial sectors, demands in terms of flexibility and hygiene management are constantly on the increase. The latest range of FrymaKoruma mills sets new standards in both areas – with no compromise in throughput.
Perforated disc mill (ML)
Size reduction and pre-milling of bulky products. Perforated disc mills are used for initial size reduction, pulping and mashing of bulky solids – all kinds of fruit and vegetables, for example. The knife arm rotates at around 3000 rpm, very close to the perforated disc, processing the product as it is fed in axially. The cutting and impact forces produced reduce size and force the product through the apertures in the disc. Perforated discs are available with a range of aperture sizes. The rotating ejector bar beneath the disc transfers the finished product to the mill outfeed.

Toothed Colloid Mill (MZ)
For size reduction in low- to high-viscosity products. The principal application for toothed colloid mills is wet milling of fluids and high-viscosity suspensions and emulsions. FrymaKoruma mills can be supplied with a range of colloid milling sets, enabling optimal tailoring to each product. The standard milling set is suitable for universal use. The coarse toothed set is ideal for size reduction of solids in suspensions, while the cross-toothed set is used where smaller particle sizes and finer dispersion are required. Adjustment of the milling gap between rotor and stator allows optimal setting for every product, while stepless milling gap adjustment is available as an option for both manual and automatic adjustment. The gap width is indicated on a gauge.

Corundum stone mill (MK)
For liquid, viscous and pasty products. Corundum stone mills are used for dispersion and wet milling of liquid through to pasty products. At the heart of these mills are the corundum stones, which are available with various grains to suit demand. The rotor element rotates against the fixed stator at high speed, achieving size reduction of the product in the milling gap through extreme shear and cutting forces. Axial milling gap control also allows adjustment of the pressure between rotor and stator, even during operation (negative gap adjustment). These units can also be fitted with automatic milling gap adjustment as an optional extra.
