FrymaKoruma Corundum Stone Mill (MK)

Corundum stone mill (MK) — reliable processing of liquid and semi-solid materials

Corundum stone mills are used for dispersion and wet milling. Their applications range from food and cosmetics to the chemical industry. At the heart of these machines are their corundum discs which are available in different grain sizes depending on product requirements and specific production conditions.


Versatile use, tailored to your needs

FrymaKoruma’s corundum stone mills are ideal for processing mustard or sesame, nut pastes and cocoa in the food sector as well as cosmetics or chemical products such as lubricants. They can be fitted with a hopper, pump or screw in order to feed the products.

As for all other products from our company, the rule here is that the machine adapts to your needs – not vice versa. The desired grinding fineness, for example, can be perfectly set, and the right corundum disks are always available for different requirements. On request, supplementary equipment can be supplied for conversions.

How it works

The material to be processed is fed in from an open hopper or in a closed piping system. The rotor element turns against the fixed stator at high speed. The product is ground between two corundum disks. The milling gap adjustment also allows the stator to be pressed against the rotor with the required pressure.
