Automatical Control of the Mixing Process

Efficiency through Intelligence

The Mixcont technology utilizes mixing devices Mixer (+Mills) as a kind of soft Dynamic Analyzer during the time when the batch is being mixed. The properties of the compound such as Dispersion/Distribution/Viscosity (DDV) are estimated in real time by means of processing of signals like torque, rotor speed, temperatures, pressure, ram position and other from mixer and/or mills. more...

Volumetric Dosing

Dosing of two-component silicones

One very interesting product development involves two-component silicones in which the material hardness („Shore hardness“) in vulcanised form can be varied by regulating the mixing ratio. Uses of these silicones include applications in medical technology. more...

Rubber Mixing Lines

Gains in energy efficiency by modernisation of mixing lines

The mixing of rubber compounds is quite energy-intensive. In abolute terms a zypical mixing line for technical rubber goods with 2 tons/hour throughput consumes about 4,5 Mio Kwh with costs of about 630.000 €. These costs are based on the consideration of DC drives, which – looking at the installed base – are standard in todays rubber industry. more...
