Aggregate machine vibrating screen

Description:

The vibrating screen with circular motion is specially designed for quarry to separate crushed stone material into different sizes, and is also used as a grading machine in coal dressing, ore dressing, construction material, electric and chemical industries. It has a feature of advanced structure, powerful vibrating forces, low vibration noise, easy maintenance, high durability, etc.

Working Principle:

The motor is driven by tire-type couplings exciter and the eccentric block produces a powerful centrifugal force by high-speed rotating, so that screen boxes make mandatory continuous circle movement. Material is driven by such force to make a continuous throw movement in the tilt of the screen surface with materials separated when throwing up and penetrated when falling down, goes round and round, complete the classifying process for the garnularities.

Feature:

1) High screening efficiency
2) High capacity and reliability
3) Long bearing lifetime
4) Easy maintenance
