Grinding
Crushing of solid matters, crystals or fibres in small parts in a fluid, e.g. active substances, colour pigments
Wet GrindingWet Grinding

FKFKFKFK
destroying of agglomerates, wetting and homogeneous dispersing in a fluid, e.g. toothpaste, lipstick
Wet GrindingWet Grinding
merging of two not mixable fluids (oil, water) under the effect of shear forces, turbulences and an emulsifier e.g. ointments, body cream
Dispersing
Emulsifying

FKFKFKFKCharacterisationCharacterisation
Effect of mechanical forces Different products are milled on our mills by
impact, pressure, shear forces, cutting or friction
Resistability - hard-elastic, fibrous fruit flesh, coconut flesh,
aloe vera plants
- hardness of crystalline parts up to mohs hardness 9.5

All mill types are constructed according to GMP guidelines
All mills can be equipped with CIP, SIP and DIP Delivery with all qualification documents, possibility
of validation All lubricants with USDA-H1 admission For clean rooms all mills can be delivered with water
cooled motors (no turbulences) Products with a viscosity from fluid to highly viscous
can be processed Due to the new modular construction all mills are easy
to handle and quickly convertable
