Abstract: The aim of the invention is to create a compact circulating grinding plant comprising a product bed comminution roller mill or roller press and a sifter device, in which the problem of mechanically transporting the grinding product that is directed through the circuit is minimized. Said aim is achieved by a circulating grinding plant in which a static cascade sifter is disposed below the gap of the roller press while a subsequent sifter, particularly a dynamic rod basket sifter, is disposed above said roller press. The sifting product discharge area of the static cascade sifter is connected to the sifting air and sifting product inlet of the subsequent sifter via an ascending duct which pneumatically conveys the product.

Abstract: An apparatus for crushing waste metal products includes a rotor having crushing means on a periphery thereof and a casing enclosing the rotor. The casing has an inlet and an outlet for products to be crushed. An exhaust gas from the casing is partly returned to the inlet of the casing by a circulator. The rest of the exhaust gas is ventilated and processed by an exhaust processor. An oxygen concentration is monitored in a gas pathway of the circulator to control the gas concentration in the casing. If the oxygen concentration is high, a water shower sprays into the casing.

Abstract: A method and apparatus for the dry grinding of solids, comprises initial coarse grinding of the solids in a controlled vortexing of a fluidized bed and directing the solid fine particles generally upwardly into a vortex grinding zone and grinding the upwardly directed solid particles in the vortex grinding zone by passing a portion of the particles through the vortex grinding zone. The vortex grinding zone comprises at least one successively vertically disposed grinding stage comprising passing particles upwardly through at least one horizontal vortex zone of an annular gap, defined by a stationary plate with a circular aperture, hereafter cleaning up the upward moving product mix by eliminating coarser particles by gravity separation with a centrifugal expelling fan and subjecting the remaining part of the upwardly particles to the vertical vortexing of a rotating semipermeable means, defined by a rotating assembly containing a broad mesh screen therein.

Abstract: Apparatus for processing coal to prevent the creation of extreme fines and to extract pyrites from the principal coal fractions in which there are two air circulating circuits having processing components which cooperate in their respective circuits to result initially in substantial extraction of fines in the first circuit while releasing principal granulated coal fractions and pyrites to the second circuit where specific gravity separation of the pyrites and principal coal fractions occur. The apparatus includes a source of drying heat added to the air moving in the circuits and delivered at the places where surface moisture drying is most effective. Furthermore, the apparatus is operated so as to reduce coal to a desired size without creating an excessive volume of extreme fines, to separate pyrites and hard to grind components by specific gravity in a region where fines are not present, and to use the extreme fines as a source of fuel to generate drying heat.

Abstract: A process for pulverizing coal to ultrafine size of a few microns, comprising conveying the coal through successive pulverizers with an inert gas, separating the ultrafine coal from the inert gas, cooling and recycling the inert gas and producing make-up inert gas by water scrubbing and alkaline or monoethanolamine scrubbing boiler flue gases to remove particulate, carbon dioxide, thereby leaving essentially nitrogen inert gas. Control of the final ultrafine particle size is achieved by regulation of the flow of conveying gas through the final pulverizer. Reject material streams are taken from the pulverizers to improve the quality of the product pulverized coal, which reject streams are burned in a furnace so as to recover their heat value.
