    Abstract: The invention relates to a method and a grinding plant for reduction of brittle material for grinding, in which material which has undergone primary reduction from a first grinding stage is delivered as fresh material to the second mill of a second grinding stage and finished product is removed from this second grinding stage, and in which the quantity of feed material of this second mill is kept constant when the quantity of finished product alters by altering the quantity of fresh material. This first grinding stage contains an air separator from which the fines are fed as fresh material to the second mill. In the event of alteration in the quantity of fresh material for the second grinding stage the quantity is kept constant by corresponding alteration of the fineness of separation of the separator of the first grinding stage. In this way a reliable and sensitive adaptation of the total throughput quantity of the second mill is achieved by relatively simple means when the finished product removed from the second grinding stage alters.

    Abstract: The invention relates to a material bed roller mill for crushing brittle material to be ground in the gap between two driven rollers which are pressed against one another with a high grinding force with a filling shaft for the delivery of material provided above the rollers. The width of the stream of material delivered to the roller gap can be altered with the aid of vertical guide walls which are adjustable at right angles to the vertical central plane of the roller mill while maintaining their vertical position. The column of material which is aligned vertically above the rollers creates pressure which is introduced fully into the material bed crushing and if required the column of material can be moved in the cross direction with respect to the rollers.

    Abstract: A method and apparatus for the two-stage crushing of brittle material comprising a roll mill and a mill connected downstream thereof, the output of the second mill being delivered to a sifter in which a second branch stream of the grit obtained in the sifting operation is returned to the roll mill and a further branch stream is returned to the second mill. A first control circuit keeps the sum of the quantity of fresh material and the quantity of grit constant, while a second control circuit divides the quantity of grit into two branch streams in such a way that the drive power of the roll mill remains constant.

    Abstract: The invention relates to a method for reconditioning a used grinding roller of a material bed roller mill having profile-members which are embedded, with a portion of the length thereof, in holes of the roller body and, with the remainder of the length thereof, project above the surface of the roller body. For the reconditioning operation, after the worn profile-members are removed, the worn surface of the roller body is turned, and a material layer is applied in a welding operation and is provided with holes for receiving new profile-members. Such a method allows particularly cost-effective reconditioning.

    Abstract: The invention relates to a method for reconditioning a used grinding roll of a high-pressure bed grinding mill. In said method, the surface of the rolling body is turned by a certain degree after removing the worn profiled members, whereupon the existing bores can be deepened to a depth that is sufficient for receiving new profiled members or new bores can be created according to a new bore pattern. New profiled members are then inserted into the bores. The inventive method allows a used grinding roll to be reconditioned in a particularly time-saving manner while economizing material.

    Abstract: The invention relates to the reduction of fine ores, whereby in a multi-stage gas suspension preheater the fine ores are preheated, calcined and then reduced in at least one lowest heat exchanger stage with the addition of a reducing agent in a delivered hot gas stream. The principal part of the reducing heat treatment of the fine ores is carried out in a reactor loop constructed in the lowest heat exchanger stage of the gas suspension preheater. The reactor loop has an uptake conduit section and a curved section adjoining the uptake conduit section and with which the reactor loop opens into at least one precipitating cyclone which is disposed downstream and for this purpose a hot reducing gas is introduced into the rising hot gas stream.
