This paper concerns so called “rolling screens”. These machines consists of circular sieve panels, stacked one above the other, which makes machine’s riddle. Screen’s sieves perform precise movement called “drunk barrel”. It is a complex and spatial movement, therefore these machines are specifically designed for screening fine and very fine grained materials. There are three types of screens drive: crank drive, drive with one rotary motovibrator and drive with two rotary motovibrators, placed symmetrically both sides of the riddle and working in conditions of mutual dynamic self-synchronization.The authors of this paper engage with two symmetrical synchronized rotary motovibrators driven screens. This drive is relatively simple and allows to achieve good process properties of sieve machine. Studies of this screen are performed using minerals (sand). The aim of the work was to present the screen study design and process study results of these machines.
