摘要： A classifying device may be used to classify a granular material flow. The classifying device may comprise a first inlet that allows a first material flow into the classifying device, a second inlet that allows a second material flow into the classifying device, a static classifier, and a dynamic classifier. The static classifier may be positioned such that the static classifier at least partially surrounds the dynamic classifier. The classifying device may comprise a distributing device that is designed in such a manner that it supplies the material flow of the first inlet to the static classifier and the material flow of the second inlet to the dynamic classifier.

摘要： The invention relates to a cement production system with a preheater for preheating the cement raw meal, a calciner for pre-calcining the preheated cement raw meal, and a rotary kiln for firing the pre-calcined cement raw meal, wherein the calciner has a riser pipe through which exhaust gases from the rotary kiln flow. The gas offtake probe is arranged in a calciner nozzle, which is formed by a nozzle-like constricted section of the riser pipe, wherein the gas offtake probe is arranged flush on the calciner nozzle of the riser pipe.

摘要： A process for the production of synthesis gas from coke is described herein. The process comprises the steps of: (a) subjecting hard coal to dry pyrolysis, resulting in the production of a gas mixture containing hydrogen, methane, nitrogen and carbon monoxide as major constituents and carbon sulphides as minor constituents; (b) subjecting the gas mixture to hydrogenation at a temperature in the range of 200 to 280° C. over a sulphidic cobalt molybdenum catalyst provided on an aluminium oxide carrier material; and (c) separating the hydrogen sulphide obtained from hydrogenation from the gas mixture.

摘要： A plant may include an offgas-producing treatment apparatus for mechanical and/or thermal treatment of an inorganic material, an oxidation catalyst downstream of the offgas-producing treatment apparatus in a flow direction of the offgas, a reduction catalyst downstream of the oxidation catalyst in the flow direction of the offgas, and a temperature-affecting apparatus for affecting the temperature of the offgas upstream of the oxidation catalyst and/or between the oxidation catalyst and the reduction catalyst. In some examples, the the temperature-affecting apparatus is controllable and may comprise at least one of an auxiliary preheater, a mixing-in device for a fluid, or a heat exchanger.

摘要： A crusher may include a crushing member that is driven in an operatively connected manner by way of an eccentric element such that material to be crushed can be comminuted by way of a crushing movement generated at least in part by the eccentric element. At least one eccentric bushing may be connected by way of an active surface to the eccentric element by way of frictional engagement. The eccentric bushing may have a pressure medium chamber that uses pressure to vary the frictional engagement between the eccentric element and the eccentric bushing. In some examples, the crusher may be of a jaw type or a cone type.
