The present invention relates to a high-speed dewatering and pulverising turbine (1) for obtaining solid pulverised particles and separating the water present, which is formed by: a) a stator (6) having circular geometry with a duct (7) at one end for the outlet of the solid pulverised particles and a duct (10) in the bottom part for the inlet of solid particles to be pulverised; b) a wheel or rotor with paddles or blades, located inside the stator; and c) a central securing assembly for adjusting and securing all the elements that form the wheel or rotor. Also described is a method for obtaining solid pulverised and dewatered particles, wherein the water present is separated.
