A vibrating flip-flow screen (VFFS) with elastic sieve mats has been widely used for screening fine-grained minerals due to its good performance. The stability of the VFFŚs dynamic response largely affects its screening efficiency and processing capacity, however, it has rarely been investigated in detail. In this paper, aiming at reducing theAlso called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process.
