[0002] Sand screener, also known as vibrating screen, fluidized bed screen, ultrasonic screen, etc., is a machine used to screen materials such as stone, sand and gravel. It uses the size difference of particles of different materials to separate sand from other impurities through vibration and screen to meet the needs of different industries. The main working principle of sand screener includes feeding, vibration, separation, discharge and cleaning steps.
[0003] When in use, the mixture to be screened is generally put into the upper part of the sand screen through the feed port. This step needs to ensure that the material is evenly distributed so that the subsequent screening process can proceed smoothly. The sand screen is equipped with one or more screens, which will move at high speed by vibrating, rotating or swinging. This vibration and movement help to disperse the mixture and move it on the screen. Due to the large size of sand particles, they cannot pass through the pores of the screen, while other smaller impurities can pass through the screen. Therefore, the sand is separated and remains above the screen to form a sand layer.
