Linear Shale Shaker Work Theory

Linear shale shaker’s vibration is from the inertial vibrator. The linear shale shaker has a motor driven vibrator, vibrator with two axles, and eccentric weight on each axle (Fig. 2-1), and rotates in the opposite direction, so it is also called linear vibration shale shaker, by the two meshing tooth wheel to ensure synchronization. When two with eccentric disc rotates, the centrifugal force two eccentric weights generated by F, offset each other in the X axis component, in addition components of the Y axis, the exciting force which results in a back and forth in the direction of Y axis, the linear track vibration sieve box reciprocating in the Y axis direction.

When using the linear shaker vibration motor vibration source, two sets must be arranged in line with its axis linear shaker longitudinal axis direction (not parallel, with an angle). Upper or lower position is both suitable for the two vibrating motors and symmetrically arranged on the screen box. Its linear shaker operation explain as below picture.

Linear vibrating shale shaker screen inclination is usually below 8 °the screen surface vibration angle is generally 45 °, sieve shaker role mainly as the linear reciprocating motion. Particles produced in the projectile and fell face down shaker, so that the material on surface of the screen during vibration constantly moving forward. Projectile and the whereabouts of the material has an impact both on the screen surface, resulting in less than sieve particles are screened separated. Inclination, vibration angle of the shaker screen surface, projectile coefficient of materials sieve screening efficiency and production capacity (capacity) with the screen surface related. In order to guarantee the same high screening efficiency, production capacity sieve, you must select the appropriate Ky (projectile coefficient) values, Ky value given the same screening round vibration method.
