The invention provides an energy-saving, highly-efficient and microvibration-type fine linear sieving
machine, which solves the technical problems of low sieving efficiency,
short life of a screen, higher consumption on
electricity required by sieving, and the like in the traditional sieving
machine. The linear sieving
machine comprises a stander, a feeding port, a coarse
powder outlet, a screen, a screen frame for fixing the screen and a vibrating screen bottom, wherein the vibrating screen bottom is fixed below the stander and is provided with a
fine powder outlet; the feeding port is formed above the stander; the coarse
powder outlet is formed at one side of the stander; the screen frame is provided with shock-absorption spokes capable of reducing the screen surface amplitude of the screen; and a high-frequency micro-amplitude microvibration device is arranged on the vibrating screen bottom. Compared with the traditional linear screen, the traditional rotary vibration screen and the traditional rotary vibration screen having the ultrasonic cleaning function as well, the energy-saving, highly-efficient and microvibration-type fine linear sieving machine disclosed by the invention has the advantages that: on the premise of same
powder sieving flow (such as 80Kg / h), the Newton efficiency of sieving can be increased to be above 90 percent from the original 30-70 percent, the service life of the screen is prolonged by more than 10 times, and the
energy consumption of
electric power required by sieving is only 7-15 percent of the original
electric power consumption.
