Vibrating screen is a new vibrating screen vibrating in a circle, with multiple layers and high efficiency. This screen adopts barrel type eccentric vibration generator, and eccentric block for swing adjustment. It has a long vibrating line, various screen specifications, reliable structure, powerful vibraing power and specially designed for quarries stone screening, and is widely used for products grading for ore, construction materials, traffic, energy, chemistry and other industries, which is an ideal equipment for crushing and sceening assembly. While small meshed screen is installed, wet and sticky materials can be sceened only by adding water to spray.
It is widely used for grading and screening materials in the following fields: minerals, quarry, building materials, water conservancy and hydropower, transportation, chemical industry, smelting and so on.Our company provides a great capability in the design and manufacture of vibrating screens for a wide range of duties. Vibrating screen is usually used to separate materials into various sizes for further processing. Vibrating screen also used as a supporting machine in stone crushing plant, or for end use, that depends on client's needing.
Features of the Vibrating Screen
1.Structure of the circular vibrating sceen is new, advanced in technical parameters, high in capacity and screen ratio.
2.This screen adopts eccentric draft and block to adjust swing, operation and maintenance is quite convinient.
3.This screen adopts spring steel knitted screen nest or perforated screen plate, which has long life span and its screen holds are not easy to be stoped.
4.This screen adopts the rubber vibration isolation spring, which has longer life span, low noice and stable resonance region.
Working Principle of the Vibrating Screen
Vibrating screens work on circular motion. The vibrating screens are mainly used in coal dressing, metallurgy, mine, power station, water conservancy project, building industry, light industry and chemical industry etc They are efficient screening machines for the classification of bulk material such as coal, minerals, coke etc There are 40 specifications for YK Series, of which the heavy duty type is for the classification of large size materials, while the Light duty type is for the middle and small size materials. Vibrating Screen moves round .It has multi-layers and is of high efficiency. The eccentric shaft vibration exciter and partial block help to adjust amplitude. The material drops down along the long line.
The working of circular vibrating screen depends on inertial motor and inertial strength produced by eccentric plate, because of the vibration of screen box, the materials are threw out, so that materials of certain size go through the screen mesh, and the screening aim is realized. Since the magnetic exciter is installed on the gravity center of screen box, the two long elliptical axis form a shape like a Chinese character, and the upper of long elliptical axis in inlet end is in the same direction with the outlet, which favors the spread of materials which is in the screen box. However, the upper of long elliptical axis in outlet end is opposite to the direction of the outlet, which can reduce the movement speed of materials, and help the difficult-screened materials go through the screen mesh. What’s more, the effective area of screen is increased because of the elliptical screen surface; as a result, the processing capacity is promoted.
Application of Circular Vibrating Screen
Circular vibrating screen is applicable for classifying stone stock in the production line of sandstone; Circular vibrating screen is widely used for classifying products in such industries as mine, building materials, transportation, energy resource, chemical industries, etc. It is the ideal equipment in the crushing and screening equipment group.
