A circular vibrating screen is a new type of vibrating screen with circular motion, multiple layers and high efficiency. It adjusts the amplitude with the cylinder-type eccentric shaft vibrator and the eccentric block. It has a long screen flow line and is applicable to various screening specifications, and it is featured by reliable structure, strong vibration force, high screening efficiency, low vibration noise, durability, easy maintenance, and safe, which is widely used in mining, building materials, transportation, energy, chemical and other industries.
1. Few wearing parts. It has few wearing parts except the screen, so it boasts a low failure rate in operation and a long service life for the whole machine.
2. Simple structure, reasonable design, easy operation, and quick removal and replacement of the screen surface, which effectively reduces downtime.
3. Reasonable motor configuration. It screens one ton of material with less electric energy and stronger power, which obviously improves the yield.
4. Strong vibration of the screen box. It can prevent materials from blocking the screen hole, contributing to high screening efficiency and productivity.
The circular vibrating screen runs in a circular or elliptical. It uses an inertial vibration exciter to generate vibration, and the vibration source is generally driven by a motor. The circular vibrating screen is a single-shaft vibrator. The main shaft on the screen box rotates at a high speed driven by the motor, and the eccentric body installed on the main shaft rotates accordingly. The centrifugal inertia force makes the free-vibrating screen box vibrate in an approximate circular track.
The circular vibrating screen is mainly composed of a screen box, screen, vibrator, damping spring device, chassis, suspension (or support) device and motor. It is a multi-layer circular vibrating screen.
