Linear Vibrating Screen

Linear vibrating screen is used to generate inertial vibration exciter, and its local oscillator with electric motor driven exciter, exciter has two axes, each axis has a heavy bias, but in the opposite direction of rotation, it is also known as the biaxial vibrating screen, consists of two gears meshing in order to ensure synchronization. When the two discs with eccentric weight rotates, centrifugal force generated by two eccentric weight, the weight of each other in the x-axis offset, in the y-axis component, the result in the y-axis direction of the exciting force to produce a back and forth, to sieve box in the y-axis straight-line trajectory to generate reciprocating vibration.

When the local oscillator using vibrating motor, the two sets must be arranged with its axis vertical axis with the vibrating screen in the same direction. 2 Vibration motors symmetrically arranged boxes in the screen above the bottom and sides may. Linear vibrating screen screen surface inclination is usually 8 ° below the angle of the vibration of screen surface is generally 45 °, the role of the screen surface in the exciter mainly as a straight line reciprocating motion. The vibration of particles in the screen surface formed under the projectile with the fall, so that the vibration of screen surface materials in the process of constant movement. Projectile material and the whereabouts of all has an impact on the sieve surface, causing the particles are smaller than the sieve screening separation. Sieve screening efficiency and capacity of the surface with the screen angle, screen surface vibration point of view, the material ejection coefficient. In order to ensure efficient screening, and sieves to the production of large quantity, you must select the appropriate value of Ky, Ky with the circular vibration value of screening is scheduled the same way.

Hanging linear trajectory vibration box, using box-type structure, Exciter, the direction and level of excitation force into 45 °. A compact box-type vibration exciter, exciter of the four eccentric weight arranged in pairs in the box outside of cabinets have a pair of meshing gears, and its role is to ensure that two pairs of eccentric weight rotating in the opposite direction, the same speed as well as two The phase relationship with each other on who exactly is to enable the screen box to make a straight line reciprocating motion. Block linear trajectory sieve shaker fitted with cylindrical exciter. Cylindrical eccentric weight exciter and shaft made of one, at the end of the shaft has a pair of gears meshing with each other in order to ensure the correct phase relationship with each other, and pass campaign.

Linear vibrating screen surface inclination due to the small screen, and sieves to reduce the height, easy process layout. As the screen surface is a straight line reciprocating motion, the above material layer on the one hand forward movement, on the one hand jump and whereabouts of the material layer by the compaction process of the role is conducive to dehydration, de-mud, off when the liquid and dense medium beneficiation Removal heavy-medium. For difficult to screen materials, such as rocks, coke, sinter, the linear vibrating screen vibrating screen surface can be used angle of 60 °.
