Abstract: A three-dimensional grinder includes: a stationary grinding chamber having a generally cylindrical wall along a longitudinal axis XX and delimiting an inner space, the chamber receiving and mixing a starting compound, and generally at least two, in a liquid medium, forming an initial mixture, the stationary grinding chamber being partially filled with a grinding body, which stationary grinding chamber includes, at a first end, an inlet introducing the starting compound and the liquid medium and, at a second end, an outlet discharging an end product formed in the stationary grinding chamber; a stirrer in the stationary grinding chamber, including a rod extending along the longitudinal axis XX, the stirrer being capable of pivoting to move the grinding body/initial mixture mass, the stationary grinding chamber including, in the inner space, a heating device to heat an area of the stationary grinding chamber. The heating device is an introduction heating device.
