Measuring Mixers
Simulate production realistically on a laboratory scale
Brabender® measuring mixers are interchangeable measuring heads which, in connection with a Plasti-Corder® Lab-Station or Plastograph®, serve for testing the processibility of thermoplastics, thermosets, elastomers, ceramic molding materials, fillers, pigments, and many other plastic and plastifiable materials under practice-oriented conditions, cost-effectively, reliably, with little expenditure of time and material.
The measuring mixers consist of a mixer backstand with gear unit and a detachable mixer bowl. In addition to the electronic safety systems, they are connected to the drive unit through a shear pin coupling protecting both mixer and drive unit from damage due to overload. The blades are made of special steel. Counter-rotation towards each other at different speeds provides for excellent compounding and mixing characteristics. Heating/cooling is done either through a liquid circulation thermostat or electrically with air cooling.

 Mixer N 50 |
The series 50 and 350 measuring mixers can be equipped with a sequencer control with up to 20 mixing steps which can be switched as a function of registered units like time, stock temperature, or energy input in AND/OR functions. Additionally, several optional sensors can be connected, e.g. for electric conductivity measurement. These mixers are the optimum tools for the development and quality assurance of elastomer compounds.
The user-optimized WINMix software provides for evaluation of the measured data in compliance with the latest standards.

User-optimized 32-bit software under Windows© 98/2000 or XP
The comfortable 32-bit software allows real multitasking. Several tests can be run and controlled on various instruments while texts or spreadsheets can be edited - all at a time from a single computer. Enter your test parameters from your computer keyboard, store them in MS Access database format together with the measuring data and results, and easily use them in other applications like word processing programs or spreadsheets.
Definition of reference curves with tolerance limits makes it easy to check already during the test whether a material meets the specifications for a certain application or not.
A powerful correlation program compares diagrams and results of up to 15 tests with each other. Test conditions and results are contrasted in tables and evaluated statistically for quickly assessing trends or irregularities.
Additional software packages enable programming of speed profiles, e.g. slow premixing and increasing or decreasing mixing speed during the test. This supplementary software can also evaluate diagrams that do not have the typical shape of a standard Plastogram.The melt temperature is also measured and recorded during the test.
