Wet grinding with unbeatable advantages: The FrymaKoruma corundum stone mills are used for dispersing and wet grinding of liquid and pasty products. The heart of these mills are the corundum stones. At high speed the rotor element rotates against the stationery stator element. In the gap between the two corundum stones, the product is subjected to high shearing, cutting and crushing forces. Amongst others, the main applications of the corundum stone mill are mustard, food and baby food, soy milk, sesame, lipstick compound, lubrication grease, coatings and varnishes.
