With an increase of ball-milling time, superior electrochemical reactivity is imparted owing to enlarged active area and increased catalytic ability. The obtained graphene nanosheets are sensitive for electrochemical oxidation of phenols (e.g., hydroquinone, p -chlorophenol, and p -nitrophenol), and thus qualified for the simultaneous sensing ...

Some technologies appeared like noise level measurements (Radhakrishnan and Sen, 1980) or continuous charge measurements, but none could provide the pulp and balls positions together. New technologies like DEM (Mishra and Rajamani, 1992) intend to simulate the inside of a ball mill but they need validation in a real-scale environment.

The continuous level sensor Another model of a float-style liquid level sensor is a continuous level sensor, which provides a 4 20mA or a 0 5VDC continuous output signal. The signal is relative to where the float is located on the stem. Because the float will be at the surface of the liquid, the actual output signal is
