An example method for operating a plant, which has at least one assembly with a rotating surface that wears to an increasing extent during the operation of the plant, may involve evaluating a wear state of the rotating surface of the assembly. Based on the wear state of the rotating surface, a manner in which the plant is operated may be modified to prolong the running time of the assembly until, for instance, a next-scheduled service or maintenance interval. The modified manner of operating the plant may be adapted to the wear state of the rotating surface. Several examples of such modifications include changing a quantity of water sprayed onto material to be comminuted, changing a quantity of grinding additive added to material to be comminuted, and/or changing a contact pressure of a grinding roll of the assembly.

A device for drying and torrefaction of at least one carbon-containing material flow in a multiple-hearth furnace includes a drying zone, a torrefaction zone, a heat exchanger for heating the drying gas flow, the discharge point of the drying zone being connected via the heat exchanger to the infeed point of the drying zone; and a combustion assembly, wherein the discharge point of the torrefaction zone is connected via the combustion assembly and the heat exchanger to the infeed point of the torrefaction zone, wherein a torrefaction gas flow discharged via the discharge point of the torrefaction zone is combusted in the combustion assembly and the resulting exhaust gas is used in the heat exchanger to heat the drying gas flow and is fed to the torrefaction zone, wherein the drying zone and the torrefaction zone comprise two separate gas circulations.

Apparatus and method for the production of cement clinker, wherein raw meal is preheated in a heat exchanger and is burnt in a kiln to form cement clinker and the exhaust gases from the kiln flow in succession through the heat exchanger and a catalytic converter, wherein the exhaust gases are analysed before and/or after the catalytic converter arid the preheated raw meal is precalcined in a calciner. Moreover, for the subsequent catalytic exhaust gas purification the provision of a calciner has the advantage that higher exhaust gas temperatures are produced so that a throughput is produced. As a result the required volume of the catalytic converter is reduced and the investment costs are lowered.
