Ns series vibrating screen is the circular vibrating screen manufactured by Luoyang Dahua that introduced advanced technology from abroad. It has multi-decks, and features with characteristic of reliable structure, strong exciting force, high screening efficiency, low vibrating noise, and easy maintenance.


1.  Advanced engineering machanics design is applied to ensure adequate strength.

2.  Leading computing technology holds a stablely fixed frequency which avoids resonance.

3.  Adoption of oil lubrication which is free from fever.

Working Principle

Circular vibrating screen is called single-shaft vibrating screen. After the vibrating screen works, the vibrator drives the screen box to make jumping movement. During this process, the material that is smaller than the sieve will drop to the lower layer, while the large size materials are discharged from outlet under continuously jumping motion and finally complete the classifying process.
