DESIGN OF NEW Grinding device for Homogenization of Mechanical Grinding METALLURGY Process

Abstract

The paper deals with an experience with innovation process of a technical solution of grinding device for homogenization of mechanical grinding metallurgy process. Milling equipment-ball mills and planetary ball mills are used for conventional mechanical material milling. Their principle is based on very fine milling of the material. As with other milling equipment, there is a milling effect by combining three factors: pressure, impact, and smearing. A major disadvantage of the previously used milling equipment is the fact that during the milling process, due to the pressure and impact of the grinding bodies, agglomerates and aggregates have been formed to a chamber wall and thus significantly reduce the efficiency of the milling process. The formation of aggregates and agglomerates is an adverse effect in the processing of fine particulate materials, respectively nanopowders.The main advantage of the invented design can be seen in the simplicity of the device, which results in the homogenization of the processed material and also in the multifunctionality of the device, whereby the device does not restrict the conditions under which the mechanical process has been used so far, i.e. it allows grinding to be done with or without adding a liquid inert phase.
