摘要： A method for jet milling of damp or wet grist in a jet mill, such that at least one of the operating parameters is appropriately selected so that a combined drying and milling process occurs in which, to obtain an end product with predetermined degree of fineness and moisture content. The specific operating mechanism required for milling is selected so that it is greater than or equal to the specific drying requirement, and the end product is released from the jet mill with the predetermined fineness and moisture content. In addition, the invention relates to a jet mill to perform this method, such that adjusting, controlling or regulating devices are foreseen for adjusting, controlling or regulating at least one of the operating parameters.

摘要： A method for dry operation of an agitator bead mill, with a mill housing that includes a grinding chamber, in which a rotatable agitator shaft extends horizontally between an input side and an output side and in which grinding media are situated. An output gas is fed into the grinding chamber on the output side, goes together with ground grist through the separation system radially with respect to the transport direction, and thus leaves the grinding chamber together with ground grist through the separation system and onward through the product output. Also disclosed is an agitator bead mill for executing the method, such that the separation system has a static sieve with a free perforated surface that is chosen in such a way that the pass-through speed of the gas leaving the agitator mill through the separation system and the product outlet amounts approximately to 10 m/s to 30 m/s.
