Abstract (en)
An immersion grinding apparatus, comprising:- a basket mill (22) comprising a rotor (44) located inside the basket (36)- at least one rotating stirrer (50) located outside the basket (36), and- a control unit (60) adapted to set the rotational speeds of the rotor (44) and of said at least one stirrer (50) to different values (n<sub>R</sub>′, n<sub>A</sub>′, n<sub>R</sub>ʺ, n<sub>A</sub>ʺ, n<sub>R</sub>‴, n<sub>A</sub>‴) lower than nominal speed values (n<sub>R</sub>, n<sub>A</sub>) when the temperatures detected by a temperature sensor (56) exceed different temperature thresholds (Tc', Ts, Tc") lower than a maximum process temperature (T<sub>max</sub>).
