Circular Vibrating Screen is a set of new and highly effective vibrating screen which can be designed with multiple layers. It is composed of screen box, screen mesh cloth, suspension (or support) device, bottom frame and motor. It is a kind of sieving equipment of international advanced level, developed by our company based on the advantages of traditional screens and absorbing the outstanding technology from abroad. Circular vibrating screen is widely used for grading and screening materials in following field for minerals, quarry, smelting, quarry, coal preparation, ore dressing, energy, power, chemical, construction material industries.
An unbalanced motor with a double extended shaft, fitted at both ends with eccentric weights. The top weight on the motor shaft rotates in a plane close to the center of the mass of assembly. Rotation of the top eccentric weights creates vibration in the horizontal plane, which causes material to move across the screen cloth to periphery increasing the horizontal throw, causing oversized material to discharge at a faster rate. The bottom eccentric weight rotates below the center of mass creating tilt on the screen giving vibration in vertical and tangential planes. Increasing the vertical component of motion, this promotes turnover of material on the screen surface helping the maximum quantity of undersize material to pass through the screen. Rugged Springs placed over the circular motor base increases the vibration.
