Method for producing classifier wheels, rotors and stators, and machine and bearing housings, also with cooling or heating ducts for wind classifiers and comminution devices, in particular classifier mills and impact mills, for fractionating, micronizing, grinding and homogenizing different products, even clumpable and sticky products

Abstract

The invention relates to a novel method for producing classifier wheels, stators or rotors for comminution devices, in particular classifier or impact mills, for grinding and homogenizing different, even clumpable and sticky products, wherein once the properties of the pulverulent, granular or fibrous products or product mixtures to be comminuted or separated are determined, a production data set for the constructive design of the stator, classifier wheel or rotor is determined on the basis of the anticipated abrasion or material properties of the products or product mixtures. The material or a material mixture is then defined and a material data set processed. On the basis of the respective production and material data sets, an additive manufacturing device, in particular a 3D printer, is commissioned, and the particular classifier wheel, stator or rotor with its predetermined use-typical properties is additively manufactured, with longer lifetimes and uniform wear in the monolithic construction with different, additively combined materials being achieved.
