ABSTRACT:
A colloid mill includes a rotor turning relative to a fixed stator with a narrow passageway therebetween through which a slurry is passed to produce a fine colloid. A cooling fluid is passed through a hollow annular passageway within the stator to cool the stator and the slurry adjacent thereto. A cooling fluid is also passed through an input tube in the center of the rotor shaft, then through a hollow annular passageway within the rotor, to cool the rotor and the slurry adjacent thereto. The rotor cooling fluid exits the rotor through an annular exit passageway between the rotor shaft and the input tube.
