Each vibration technique guarantees that, if the particles are tiny enough, they will have a chance to pass through the screen mesh between the beginning and end of the deck. Each design is available in basic proportions, but it can also be customized with other deck systems, such as wire mesh, steel, rod decks, or polyurethane panels.
With the rapid development of petroleum exploitation industry, vibrating screen actuated with a single frequency is unsuitable to separate cuttings from drilling fluid, since it usually results in screen blocking. Hence, for solving the above-mentioned problem, tri-motor excitation with double-frequency in far resonance system is introduced. This …
