COMMINUTING APPARATUS WITH COOLING DEVICE AND METHOD OF OPERATING THE SAME
A comminuting apparatus adapted to carry out a comminuting process comprising a comminuting rotor which is mounted to a machine frame and which has a plurality of comminuting tools at its periphery, wherein the comminuting rotor is arranged in a comminuting chamber for receiving comminution material and is adapted to comminute the material in the comminuting chamber, further including a cooling device adapted to introduce a liquid coolant including at least 80% water into the comminuting chamber and including a control device for controlling the cooling device to set a rate of introduction of the coolant into the comminuting chamber. The comminuting apparatus according to the invention is distinguished in that the control device is designed and configured to adapt a rate of introduction of the liquid water-based coolant into the comminuting process to an operating parameter of the apparatus, that is dependent on the quantitative throughput of the comminution material, in such a way that more than 60% of the cooling capacity introduced into the comminution material is provided by the latent heat of the liquid water-based coolant. The invention further concerns a method of operating an apparatus.
Mineral material processing method and processing plant
In a mineral material processing method, mineral material is processed in a mineral material processing plant. Heat generated in heat sources of the processing plant and/or fuel used in a motor of the processing plant is cooled in a cooler of the processing plant. The cooler is equipped with a blower. Wetting water is directed to the mineral material for binding dust generated in the processing. Heat of at least one heat source of the processing plant and/or heat of the fuel is transferred to the wetting water before using the wetting water for dust binding. The wetting water is directed, before the dust binding, to a first heat exchanger for receiving heat in the wetting water.

Methods for processing heterogeneous materials
A method of processing a heterogeneous material includes entraining heterogeneous particles into a fluid stream. Each of the heterogeneous particles comprises a liquid portion and a solid portion. The fluid stream is passed through at least one adjustable nozzle, and is impacted to dissociate the liquid from the solid. A method of separating oil from solid particles includes mixing oil-coated solid particles with water to form a slurry, passing a first portion of the slurry through a first nozzle, and passing a second portion of the slurry through a second nozzle such that the second portion of the slurry intersects the first portion of the slurry to separate the oil from the particles.
