vibration shaker working principle

Detailed shaker works

Shaker can be used for screening and grading operations metallurgy, coal, electricity, foundry, chemical, mineral, cement, glass, ceramics, refractories, food and light industry and other industrial sectors of bulk materials.

This shaker from the screen box (box), screens, vibrating motor, as well as the upper and lower plate composed of one, freedom is mounted on four spring bearing. Its structure is characterized by a simple solid structure, light weight, reliable, transparent screen is good, the production volume can be adjusted.

Its working principle is: the same performance model with two vibration motors installed in the same mounting angle on each side of the screen frame, so that the two eccentric eccentric vibration motors same scale. Two vibrating motors rotating in opposite directions at the same time, starting at the beginning of the same or different phase angle difference is not large resistance moment, they always automatically tracking to achieve minimum energy consumption along the route from the sync.

When two eccentric vibration motor in the same direction at the moment, the centrifugal force generated by the two vibration motors with an eccentric block is generated from the sum; When two partial vibration motor in the opposite direction at the moment the heart, the two forces are equal in magnitude, direction, Instead, cancel each other; vibration motor when the two eccentric force at other locations, the reverse rotation of its symmetry, the horizontal force equal and opposite, the two forces balance, with the sum of the force. Thus, each rotation cycle, there are two points to two opposite points to the same maximum force moment, two opposite forces force is zero, the two forces in the same direction as well as increases to the maximum moment, and opposite force is gradually reduced to zero , which constitutes the linear vibration trajectory.

The screen surface material movement both up and down in points, and points while jumping forward movement, suffered much greater than the material of the vertical force of gravity and gravity, easy to sift through, the horizontal force to facilitate the forward movement of the material, so that later Material is also the location of the front of the material out of the screening. Changes in vibration motor eccentric position, you can easily adjust the working vibration, thereby adjusting the intensity of the sieve screening machine.
