Mill Measuring System Grind Control

Achieve optimal ball milling processes with GrindControl

The GrindControl system continuously measures and records the pressure and temperature inside the grinding jar. This gives users clear insight into the milling process and ensures reliable, reproducible conditions. By monitoring these key variables, sample preparation becomes more efficient, temperature sensitive materials are protected, and stable conditions for colloidal or long term grinding are maintained. GrindControl also supports demanding applications such as mechanical alloying and mechanochemical synthesis by enabling precise process control.

GrindControl is available for the Mixer Mills Mixer Mill (Net weight – 60 kg NANO)/control, the High Energy Ball Mill Emax, and planetary ball mills. It consists of a hardware measurement unit and analysis software.

SYSTEM AVAILABILITY

The GrindControl system is available for the Planetary Ball Mills, the Mixer mills MM500 nano/control, and Emax. It includes hardware for pressure and temperature measurement plus analysis software.

FUNCTION PRINCIPLE

A Bluetooth transmitter integrated into electronic unit of the lid sends pressure and temperature data to the PC using a secure industrial protocol. A protective filter prevents contamination of the pressure sensor. The GrindControl software records all data in real time and stores them in a consecutive list. Measurements can be exported as .csv for further processing.

• Monitoring temperature and pressure during grinding is essential for both research and quality control.

• It helps to improve:

• Quality : Temperature strongly influences material properties. Monitoring ensures consistent sample quality.

• Efficiency : Temperature and pressure significantly influence the grinding outcomes of many materials, as well as the results of mechanochemical processes. Real-time monitoring enables precise control of operating conditions.

• Safety : High temperatures and pressures can pose risks. Monitoring keeps the process within safe limits.

• Mechanochemical insights / Error detection: Sudden changes in temperature or pressure may indicate chemical reactions or process deviations. Continuous monitoring enables early detection, better understanding of mechanochemical processes, and quick troubleshooting.
