The method and the equipment are used for dry grinding ofsolid substances which are initially rough grinded in a controllededdy of a fluidized bed. The solid fine particles are directedupwards in an eddy grinding zone and by the transition of part ofthem through it they are ground there. The zone includes at leastone grinding platform fitted vertically in sequence engaging thecrossing particles in at least one horizontal eddy zone of aring-like aperture formed across a stationary plate with aring-like hole. The moving product is cleaned in its ascendingposition the rough particles being eliminated by means ofgravitational separation by a centrifugal ejection fan and theresidual part of the ascending particles is subjected to avertical eddy current by a revolving semi-permeable device havinga revolving part including a transit mesh-screen in it.62 claims
