Abstract (en)
[origin: US4682739A] Device for projecting solid particles for a vacuum centrifugal grinder incorporating a rotationally driven distributor wheel (20) in which a plurality of ejection channels are formed. The particle-guiding face in each channel (21, 22) has a curvature (A) extending in the direction of rotation of the distributor wheel (20) and whose outline, calculated as a function of the friction coefficients of the materials in contact, produces the attachment to said curvature (A) of a stable self-protection layer (30) consisting of the particles themselves, with automatic regeneration of the layer as it wears. The invention applies, for example, to the grinding of cement or pulverized coal.
