Vibrating screen linear vibrating screen self centering vibrating screen model

Vibrating screen linear vibrating screen   Model of self centering vibrating screen
Self centering vibrating screen is used for coarse, medium fine and very fine screening of ore, coal and other materials
It can also be used to remove cement and media from materials
The structure of self centering vibrating screen is mainly composed of screen box, vibration exciter, suspension (or support) device and motor
The motor drives the main shaft of the exciter to rotate through the V-belt
Due to the centrifugal inertia force of unbalanced organisms on the exciter, the screen box vibrates
Change the eccentric weight of the exciter or obtain different amplitudes

Product structure and material:
 
Working principle of vibrating screen
When the vibrating screen is working, the two motors rotate synchronously and reversely, so that the exciter generates a reverse exciting force, forcing the screen body to drive the screen to move longitudinally, so that the materials on it are periodically thrown forward a range by the exciting force, so as to complete the material screening operation

Classification of vibrating screen (simple summary for reference only)
According to the structure and working principle of screening machinery, there are roughly the following categories:
(1) The working part of the fixed screen is fixed, and the materials are screened by sliding along the working surface
Fixed grid screen is a kind of screen widely used in concentrators, which is generally used for pre screening before coarse crushing or medium crushing
The utility model has the advantages of simple structure and convenient manufacture
Without power consumption, ore can be directly unloaded onto the screen surface
The main disadvantages are low productivity and screening efficiency, which is generally only 50— 60%。
(2) The working surface of the roller screen is composed of one rolling shaft arranged horizontally
There are plates on the shaft, and the fine materials pass through the gap between the rollers or plates
Large pieces of material are moved towards one end by the roller belt and discharged from the end
This kind of sieve is rarely used in concentrators

(3) The working part of the cylindrical screen is cylindrical, and the whole screen rotates around the axis of the cylinder, and the axis is generally installed at a small inclination angle
Materials are fed from one end of the cylinder, fine materials pass through the screen holes on the cylindrical working surface, and coarse materials are discharged from the other end of the cylinder
The rotary speed of the cylinder screen is very low, the work is stable and the power balance is good
However, the screen hole is easy to be blocked, the screening efficiency is low, the working area is small, and the productivity is low
Concentrators rarely use it as screening equipment

(4) The plane motion screen body swings or vibrates in a plane
According to its plane motion trajectory, it can be divided into linear motion, circular motion, elliptical motion and complex motion
Shaking screen and vibrating screen belong to this category
