 Mixing and.Kneading machines.
Economical discontinuous mixing and kneading.
| |
|
|
|
| |
| Ideal for all mixing and kneading procedures – the UK Universal kneader. |  | |
Since Coperion Werner & Pfleiderer built the first mixing and kneading machine over 100 years ago, thousands of laboratory and production machines of the Universal kneader series have been installed around the world for preparing medium-viscosity and high-viscosity compounds in batch processing operations. The adaptability of our LUK and UK laboratory and production machines means that their range of uses extends across a wide variety of industries, from rubber to plastics, paints, adhesives, pharmaceuticals, cosmetics, foods up to the general chemical industry.

The principle of operation. The mixing and kneading effect of our LUK laboratory machines and UK production machines is achieved
by one of the following principles of operation:
| - | | The twin-blade principle – two blades rotate at different speeds tangentially to one another |
| - | | Blade-screw principle – during the compounding phase, the discharge screw reinforces the mixing process |
The interaction of the shear rate generated between the trough and the blades (and, where applicable, the discharge screw too), the speed and the friction of the blades and the blade setting (which depends on the product) ensure an extremely intensive mixing and
kneading of the raw materials.
The possible process steps within a single mixing cycle are:
| - | | Mixing |
| - | | Kneading |
| - | | Moistening |
| - | | Plasticising |
| - | | Dispersing |
| - | | Homogenising |
| - | | Melting |
| - | | Cooling |
| - | | Degassing |
| - | | Evaporation |
| - | | Dissolving |
| - | | Reacting |
