This machine passes the adjustable speed motor's major movement to the eccentric axle by the triangle belt, the eccentric axle connects the machine body by the bearing and the seat, passing the adjustable speed motor's rotatory movement to the body, then makes use of the front pivot point and spring to turn the rotatory movement into the full vibration, realizing the aim of feeding. 

Performance features:

1. The grain size of charge is big, the productivity is high. 

2. The structure is compact, the vibration is stable, the operation is reliable, the operating life is long.

3. It can size the materials, excluding all sorts of impurities

4.There is splined joint among the gears, and durable in use.

Applicability:

Widely applied to the materials' breaking crafts, such as building materials, mine, coal, chemical industry, it is an ideal matching device of breaking machinery.
