Circular Vibrating Screen
NT-YK Series Circular Vibrating Screen
Introduction
The NT-YK Series Circular Vibrating Screen is a multi-layer, high-efficiency screening machine designed for dry material classification in metallurgy, coal, mining, building materials, transportation, energy, and chemical industries. It performs circular motion screening, making it a new generation of versatile screening equipment suitable for a wide range of material types and production capacities.
Henan Innovative Industry manufactures NT-YK Circular Vibrating Screens with processing capacity from 8 to 800 m³/h, maximum feeding size of 400 mm, screen size from 4 to 100 mm, and motor power from 5.5 to 22×2 kw. Available in 2 deck, 3 deck, and 4 deck configurations.
Vibrating screen is the essential screening equipment in all kinds of sand production lines, mainly used for screening of dry materials in metallurgy, coal, ore and other materials. It is widely used for product classification in mining, building materials, transportation, energy, chemical industry and other industries.
Vibrating Screen separates materials into various sizes for further processing or end use. The material passes through a vibrating screen box which has a number of different sized meshes, through which the material falls like a sieve and moves to attached conveyors to become end products.
The difference between circular vibrating screen and linear vibrating screen is that circular vibrating screen performs circular motion, making it a new type of multi-layer and high-efficiency screening equipment.

STRUCTURE & WORKING PRINCIPLE OF CIRCULAR VIBRATING SCREEN
The NT-YK Circular Vibrating Screen is mainly composed of a screen box, vibration exciter, suspension or supporting devices, and electric motors. The motor drives the spindle to rotate through a belt. The unbalanced centrifugal inertia force of the eccentric weights in the vibration exciter causes the screen box to vibrate. The amplitude can be adjusted by changing the eccentric weight on the exciter.
Circular vibrating screen is a single-axis circular-movement inertial vibrating screen, whose working depends on inertial motor and inertial strength produced by eccentric plate.
Because of the vibration of the screen box, materials are thrown out so that materials of a certain size pass through the screen mesh, achieving precise screening. Since the magnetic exciter is installed on the gravity center of the screen box, the upper part of the long elliptical axis at the inlet end moves in the same direction as the outlet, promoting material spreading across the screen surface.
At the outlet end, the upper part of the long elliptical axis moves opposite to the outlet direction, reducing material movement speed and helping difficult-to-screen particles pass through the mesh. The elliptical screen surface also increases the effective screening area, improving overall processing capacity.
