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 EL
PUC type EL colloid mills are designed for in-line operation. They can be supplied many widely used types of connection (threaded nozzle, flange, tri-clamp, etc.). A special feature of type EL is the bearing block that allows our customers to use their own standard motors (standard B3 motors). At high inlet pressures and viscosity values, the forces generated can be absorbed even more effectively by the separate bearing. Our bearing blocks are fitted only with high-quality bearings with permanent lubrication, made in Germany.
Sizes
Type EL colloid mills are available in eight standard sizes with capacities between 150 and 80,000 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.
