    摘要: Fine-grained material adapted to be fired in a furnace is discharged from a preheater into a gas conduit extending from the furnace to the preheater and through which a stream of hot gases pass. The conduit is shaped to deflect the gas stream and concentrate it along one side of the conduit in the area of introduction of the material to the conduit. Below the area of introduction of material to the conduit fuel burners provide a heating zone through which the material falls. The concentration of the gas stream along one side of the conduit assures entrainment of the material in the gas stream and passage of the material again through the heating zone. Above the area of introduction of material to the conduit the latter is shaped to deconcentrate the gas stream and permit some of the material entrained therein again to fall downwardly through the heating zone, following which such material is reentrained in the gas stream.

    摘要: The invention relates to a roller mill with two rollers, a grinding gap formed thereby and a material inlet shaft the end walls of which bear on their lower ends carrier plates with replaceable sintered metal wear parts. Each wear part is formed by a plurality of small sintered metal plates of small area which are set close against one another like a mosaic and are individually screwed onto the carrier plate so that in case of wear only those small sintered metal plates which are actually worn can be replaced simply, quickly and economically.
