摘要： A method for the oxidation and sintering of pellets includes the introduction of a first medium into a compartment through an inlet connected to the compartment and the heating of the medium in the inlet through the use of a combustion arrangement. The use of the combustion arrangement includes the ignition of the fuel, the combustion of the fuel, and the transfer of combustion heat to the first medium that is present at the combustion arrangement. In a region in the inlet outside the direct passage of the first medium, the ignition of the fuel, the combustion of the fuel and the transfer of combustion heat to the first medium take place. By the introduction of a second medium into the region in the direct vicinity of the combustion arrangement, the combustion of the fuel and the transfer of combustion heat also to the second medium take place.

摘要： Process for the determination of the magnetite and phosphorus contents of magnetite-containing ores. A sample of dust which has been produced artificially or obtained as byproduct is collected and placed in an electromagnetic field. The magnetite content of the dust sample is determined from changes in the magnetic flux or the relative permeability. Subsequently the phosphorus content of the total dust sample mass is determined. Also the total dust sample mass is likewise determined from changes in the magnetic flux or the relative permeability. The dust sample is preferably dried prior to measuring the change in the magnetic flux or the relative permeability. Equipment for carrying out the process includes a coil system having at least one measuring coil for determining the magnetite content. The core of the measuring coil forms a tube which has a minimum filling height that exceeds the length of the coil. An additional measuring coil, whose length exceeds the maximum filling height of the tube, is provided for determination of the sample mass. The tube is connected to a reaction chamber for carrying out the phosphorus analysis. The reaction chamber is connected to reagent storage containers. A microprocessor is provided for evaluating the measured values and simultaneously controlling the operation of the equipment. The tube is connected to a dust collecting unit, preferably via an elbow.

摘要： The invention relates to a roll screen having variable screening apertures having axle-fitted rolls which are spaced at adjustable distances apart and a device for adjusting this spacing. The roll spacing adjusting device functions to act on all rolls simultaneously, so that the spacing change will be the same for all rolls. The device includes two parallel running tracks (10, 11) and the distance between these tracks can be varied. A change in the distance between the running tracks causes the roll axle housings (6) to rotate and move the axles (2). This roll screen also includes a device for adjusting the individual distance between two consecutive rolls without affecting the distances between the remaining rolls. This device includes a spacer (32) which is inserted between the housings of the two rolls in which the roll axles are journalled. The roll screen is also provided with a separate elastic sealing element between the roll axle and the roll drive arrangement.
