PUC colloid mills have a wide range of applications. They can always be used when it is necessary to grind substances precisely and with reproducible results while mixing them at the same time. The milling gear of a colloid mill exerts hydraulic and mechanical cutting, impact, squeezing, friction and shear forces.
The phases are ground and mixed with considerable precision in an annular gap between the two major components, stator and rotor which can be infinitely adjusted by changing the axial position of the stator. Particles are ground extremely finely. Most raw materials, aggregates and agglomerates can be processed in one pass through the mill.
PUC type O colloid mills have a fully enclosed motor. They are always operated in a vertical position. Materials can be fed to the mill via various different types of hopper adapted to your process or via piping flanged directly to the mill.
Type O colloid mills are available in seven standard sizes with capacities between 150 and 34,000 l/h depending on the machinery configuration and the viscosity of the product. The milling gear can be adapted to your specific process. For this purpose, the mills are fitted with standard stator-rotor combinations. Bespoke solutions are also available for special applications.
All units are available with various single and double-acting mechanical seals and with lip seals (PTFE) in accordance with FDA requirements. The seal is integrated in a seal mount which is identical for all types and sizes of colloid mills. This facilitates the installation of the seal and later replacement with a different seal system, if necessary.
For most PUC mills, a variety of accessories and options are available, including:
- optional milling gears
- various material options
- recirculation system for recirculation of material through the milling gear
- heated/cooled housing
- pharmaceutical version
- ATEX (explosionproof) version
- version designed for sterilization
- feed and discharge pump
- feeder screw with controlled gearbox
- mobile version
- frequency converter
- IE3 standard motors for various voltages and frequencies
