Functional Description

Toothed colloid mills are used primarily for wet milling of products in a wide viscosity range. Depending on the application, the mills are installed in vertical or horizontal orientation. The standard version has a fixed adjustment of the gap between rotor and stator. This facilitates an optimized grinding gap for each application. Stepless adjustment of the grinding gap with manual or automatic controls is available as an option. The universal grinding set is suitable for a wide range of applications; alternative grinding sets for specialist requirements are available.
The coarse toothed colloid head is recommended for solid ingredients, while intensive milling and dispersion is achieved with the cross-toothed grinding head. Product is fed either from a hopper (vertical execution) or by pump. All static seals are easily accessible, contributing to straightforward and thorough cleaning of the machine.
