The screen is one of the main technological machine in all installation for minerals processing. Role and tasks of the screen is are decisive for the whole process and often it decides about beneficiation results, that is why so mach attention is paid to its design and operation. That machine undergoes the process of continuous improvement of technical and technological parameters. The design proposal, presented in the article, relates to theoretical grounds and has been compared with the solutions of similar functions used in the Polish mineral processing plants. The screen having a broken deck line, set to vibration move by the single inertial drive, realizes a dry classification process with circle-and-elliptical trajectory, according to the rule of “angles of slide” and with acceleration. of 5g The machine is a very important component of the washery jig installation, which can improve the processing products quality and first of all it enables to reduce operational costs. KOPEX S.A. with a co-operation of other companies plans to carry out the classification process by using this machine in Polish and foreign processing plants.
