Summary
  The machine is composed of three parts: the screen box at the inlet and outlet, the vibration source and the shock absorber. The machine base and screen box are connected with 4-6 sets of soft rubber shock absorbers which are fixed up and down. Centrifugal force is generated when the machine is started. The amplitude is controlled by eccentric blocks and shock absorbers, so as to achieve the required working performance and make the material have a shock-proof and loose screening process. Ideal equipment for screening in pharmaceutical, food, chemical, metallurgical, electronic and other industries.
