Thanks to the belt-pulley mechanism driven by an electric motor, the rotational motion is transferred to the sieve shaft. The sieve weights, which are placed unbalanced, connected to the sieve shaft, make the sieve vibrate. The position of the screen weights can be adjusted around the screen shaft in order to change the vibration amplitude of the screen. The screen is hung on the ceiling of the place where it is located by means of composite rods in order to create the vibration comfortably.
Thanks to this vibration movement, in specially designed sieve boxes, the incoming product is classified and sifted according to its grain size. The product to be screened is sent to the screening area through one or more inlet pipes. Various types of silk-covered cases allow separation in seven channels. This part is directed to the outlet by the channel. After the product is sifted, it is sent to the outlet pipe on the bottom plate. It also has sight pipes for product control and monitoring. Sieves with 4, 6, 8 and 10 passages are produced. The screen is suspended with different amounts of composite rods according to the number of passages and weight of the screen.
Each passage has a clamping device to prevent passage between cases. The maximum number of outlets of passages is 8, and the outlets have a maximum diameter of 150 mm.
