FKFK Pharma/Cosmetics 2 uDefinition Grinding, Wet Grinding uCharacterisation uModula Grinding Aggregates uAnnular Gap Mill CoBall-Mill uApplications uSummary Contents
3
FKFK Pharma/Cosmetics 3 We differentiate between: Wet Grinding Grinding Dry Grinding u u Grinding u u Dispersing
4
FKFK Pharma/Cosmetics 4 Grinding uCrushing of solid matters, crystals or fibres in small parts in a fluid, e.g. active substances, colour pigments Wet Grinding
5
FKFK Pharma/Cosmetics 5 udestroying of agglomerates, wetting and homogeneous dispersing in a fluid, e.g. toothpaste, lipstick Wet Grinding u umerging of two not mixable fluids (oil, water) under the effect of shear forces, turbulences and an emulsifier e.g. ointments, body cream Dispersing Emulsifying
6
FKFK Pharma/Cosmetics 6 Characterisation u u Effect of mechanical forces Different products are milled on our mills by impact, pressure, shear forces, cutting or friction u u Resistability - hard-elastic, fibrous fruit flesh, coconut flesh, aloe vera plants - hardness of crystalline parts up to mohs hardness 9.5

11
FKFK Pharma/Cosmetics 11 Perforated Disc Mill M/ML Crushing, Pre-grinding u u Size up to 100 mm u u Fineness approx 1 mm The desired fineness is adjusted by the size of the holes in the perforated discs Hole dia. 1.5 to 20 mm or slotted discs
12
FKFK Pharma/Cosmetics 12 Toothed Colloid Mill M/MZ
13
FKFK Pharma/Cosmetics 13 Toothed Colloid Mill M/MZ Fine Grinding u u Starting size depending on product up to 5mm u u Fineness approx 100 µ The desired fineness is adjustable with u u Toothing, coarse, normal, crosswise u u Grinding gap infinitely adjustable (gap between rotor and stator)
14
FKFK Pharma/Cosmetics 14 Corundum Stone Mill M/MK
15
FKFK Pharma/Cosmetics 15 Finest Grinding u u Fineness 30 - 50 µ Corundum Stone Mill The desired fineness is adjustable with u u Different graining of grinding discs grain 20 to 120 u u Grinding gap infinitely adjustable (gap between rotor- and stator disc)

24
FKFK Pharma/Cosmetics 24 Finest grinding down to the Nano range < 0.5 µ Adjusting Possibilities u u Rotor speed u u Diameter of grinding beads and grinding gap (rotor). u u Material of grinding beads (spec. weight ) CoBall Mill u u Degree of beads filling u u Capacity u u Product temperature u u Product viscosity (contents of dry substances )
25
FKFK Pharma/Cosmetics 25 CoBall Mill MS-12 MS-50
26
FKFK Pharma/Cosmetics 26 CoBall Mill Advantages u u Narrow grinding gap (four times beads diameter) high energy density narrow grain spectrum u u Optimum cooling, all surfaces rotor, stator, lid coolable u u Smooth grinding elements resistant to wear, no pins, naps etc.
27
FKFK Pharma/Cosmetics 27 CoBall Mill u u Products from fluid to very viscous can be processed u u Cleaning, sterilizing and drying without emptying of grinding beads u u Small grinding chamber volume - Little remnants at product change - Quick cleaning, little consumption of cleaning material - Easy and efficient change of products
