The GrindControl monitors and records the development of pressure and temperature of a ball mill process.
Monitoring the two variables "pressure" and "temperature" provides valuable information about what is happening inside the grinding jar. GrindControl is used to improve sample preparation, for example of temperature-sensitive materials, to control colloidal or long-term grinding processes, or to successfully perform material synthesis such as mechanical alloying or mechanochemical processes.
The GrindControl system is available for the planetary ball mills PM 100, PM 300 and PM 400 as well as for the Mixer Mills MM 500 nano and MM 500 control and for the High-Energy Ball Mill Emax. The system consists of the pressure and temperature measurement hardware and an analysis software.
A transmitter is integrated in the lid and sends the signals of the pressure and temperature sensor data to a receiver that is plugged into the PC. A secure industry standard protocol is used for transmission. To detect the temperature inside the grinding jar, the temperature sensor is thermally decoupled. A filter is used to protect the pressure sensor from contamination.
The GrindControl software is an intuitive program that allows to record the measured variables in real time making them available for later evaluation. The measurement data is transferred to the PC and a measurement protocol is stored in a consecutive measurement list. The data can be exported for further processing.
