The motor generates high-speed rotation of the eccentric block of the exciter through the triangle belt. The running eccentric block generates a large centrifugal force, which stimulates the screen box to produce a circular motion with a certain amplitude. The material on the screen is subjected to the impulse imparted by the screen box on the inclined screen surface to produce a continuous throwing motion. The process where the material meets the screen surface The particles smaller than the mesh size are passed through the sieve to achieve classification.

The tracked mobile screening plant can be directly opened to the work site. It is convenient for transfer operations and high screening efficiency. It is very suitable for narrow terrain, urban demolition and other complex terrain areas.
The mobile screening equipment adopts the main structure of the double or three-layer screening machine, and is equipped with an excellent grid screening channel. It can stand freely without support.
Fuel economy is saved. The crawler screening station meets the needs of environmental protection and can save costs. It can screen out 3 or 4 different specifications of aggregates according to the customer's choice.
