Abstract:

The necessity of improving technological operations in the processing of mineral raw materials and the use of energy-efficient grinding equipment is substantiated. The technical and technological benefits of vertical dynamic autogenous grinding mills are given. They are based on a method of self-grinding of the material, which allows to reduce the specific energy consumption. The technical advantages of the MKAD system mills, the structural schemes of which have an indifferent group are explained. Since the mills of this system additionally use so-called “circulating” energy, depending on the

Background. One of the problems in the production of powder structural materials based on iron alloyed with a small amount of alloying elements (0.5 - 5.0 wt.%) is obtaining a homogeneous alloy in the final material. The distribution uniformity of the alloying elements largely determines the final properties of the material. The use of a mixture of powders constituting the alloy to obtain such alloys, in manycases, does not solve the problem of obtaining homogeneous alloys. Promising in this respect is the use of alloy powders containing alloying elements as sources of alloying elements.Object
