Introduction The main function is to provide accurate separation of materials without product deterioration, thereby resulting greater product yields at higher production rates. This screening equipment consists of Supporting rack, screen frame, the cleaning ball, side plate, screen box, deck, screen assembly, etc. The unique gyratory motion of the near horizontal screen surface and the available screen mesh cleaning system secure the M&Y gyratory vibrating screen quality as a high capacity product that efficiently developed for materials screening purposes. Functional principle M&Y gyratory vibrating screen puts the distribution of material device and screening plant together as it passes along the screen surface. It begins with a horizontal circular motion at the feed end, gradually changes to changes to elliptical motion at the center, and finally to a straight-line motion at the discharge end, keeping the material in constant contact with the screen surface without deterioration. Advantages No vertical vibration, longer life span of screen deck. All components are easily accessible and removable for ease of teardown and cleaning. Due to adopting the principle of plane rotary, thus improving the effective utilization rate of screen surface and eventually improving the screening efficiency.
