Retsch PM GrindControl Pressure and temperature measuring system, with grinding jar "comfort" 250 ml, stainless steel
In order to understand the processes which occur during grinding with ball mills (e.g. chemical reactions, phase changes), it is helpful to record the most important thermodynamic parameters: pressure and temperature. Planetary ball mills are frequently used for the development of new materials by mechanical alloying due to their high energy input. The processes and reactions which take place in the grinding jar during grinding can be monitored and recorded. The PM GrindControl is available for stainless steel grinding jars of 250 ml and 500 ml. The complete system including accessories is delivered in an aluminum case.
Application Examples
The processes and reactions which take place in the grinding jar during grinding can be monitored and recorded.
Product Advantages
- measurement ranges: gas pressure: 0 - 500 kPa / temperature: 0 - 200°C
- no modification of the mill required
- indoor range up to 20 m
- operating time with fully charged accumulator 80 h
- evaluation of data with Windows XP/Vista
- multilingual software
Function Principle
A transmitter which is integrated in the jar lid sends digital signals to a stationary receiver which is connected to a PC. Up to 200 values are measured per second (single transmission mode). The transmission protocol is a very safe industry standard. Once the data is transmitted to the PC, it can easily be processed with established office programs.
incl. measuring transceiver, stationary transceiver, software, case and grinding jar for PM 100 and PM 400
