Applications
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 at the same time as mixing them. 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 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.
Type E
PUC type E colloid mills are designed for in-line operation but can also be used for batch operation with an optional hopper. If required, type E colloid mills can to be supplied with many widely used types of connection (threaded nozzle, flange, tri-clamp, etc.).
Sizes
Type E colloid mills are available in six 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.
Seals
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.
