Abstract (en)
[origin: WO2008074811A1] To coat pulverulent material with a meltable coating material, more particularly to coat CaCO<SUB>3</SUB> with stearic acid or technical grade stearic acid, a mixture of the materials is heated in a gas stream, such that the coating material melts and the mixture is dispersed, the mixture is fluidized in order to contact the material to be coated with the coating material, the coated material is cooled in order to consolidate the coating, and the coated material is removed from the gas stream. The gas stream in which the mixture is heated is directed first vertically upward and then vertically downward.
