Description of vibrating screen

The vibrating screen is a kind of sieving equipment of international advanced level, developed by our company on the basis of carrying on the advantages of traditional screens and absorbing the outstanding technology from abroad.

SBM circular 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 YA 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.

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.

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.

• Circular Vibrating Screen uses eccentric block to produce strong exciting force.
• Crossbeam and the main body of the screen are connected with high strength screw bolts. So they have the features of simple structure and easy maintenance
• Circular Vibrating Screen adopts tire clutch with capability of flexible connection and stable operation.
• Circular Vibrating Screen adopts the structure of small amplitude, high frequency, large obliquity to make the screen hold the capability of high efficiency, large handling capacity, long life span, low consumption, little noise.

Circular vibrating screen is single-axis circular-movement inertial vibrating screen, 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.
