The vibrating screen works with the vibration of the reciprocating rotating type produced by the excitation of the vibrator. The upper rotary weight of the vibrator makes the sieve plane produce plane cyclotron vibration, while the downward rotating hammer makes the screen surface produce the conical rotary vibration, and the effect of combined effect makes the screen surface vibrate again. Its vibrational trajectory is a complex space curve. The curve is projected into a circle on the horizontal plane, and the projection on the vertical plane is an ellipse. The amplitude can be changed by adjusting the exciting force of the upper and lower rotating heavy hammer. While adjusting the space phase angle of the upper and lower heavy hammer, the curve shape of the motion track of the screen can be changed and the motion track of the material on the screen can be changed.

The Chinese name is vibrating screen, which has the advantages of high efficiency, light weight, screening dry materials, mining vibrating screen, fine vibrating screen, sieve shaft principle, vibrator reciprocating rotary vibration, and working discipline ecological environment.

Brief introduction editor

It is a filter mechanical separation device used for solid phase treatment of mud, composed of sieve and vibrator. The thickness of the screen is expressed in the eyes, and the coarse screen net is below 50 eyes, and more than 80 eyes are fine screen. The vibrator is an eccentric wheel, which is driven by the motor to make the sieve frame vibrate. Because of the vibration of screen rack, when coarse mud is flowing to the screen surface, the coarser solid particles remain on the screen surface, and are discharged from one end along the inclined plane, and the fine solid particles and mud liquid flow through the sieve hole to the mud pool.

The structure and advantages of circular vibrating screen (circular motion of the material on the screen) according to the circular motion track

According to the track of the reciprocating movement, the fine screening machine (the material is moving forward on the screen to do the reciprocating movement)

The vibrating screen is mainly divided into linear vibrating screen, circular vibrating screen and high frequency vibrating screen. The vibrating screen can be divided into a single shaft vibrating screen and a double shaft vibrating screen according to the type of the vibrator. The single axis vibrating screen uses single unbalance vibration to make the sieve box vibrate, the sieve surface is tilted, and the motion track of the sieve box is generally round or oval. The double axis vibrating screen is a double unbalance vibration excited by synchronous revolving, the sieve surface is horizontal or gently inclined, and the motion track of the sieve box is straight. The vibrating screen has an inertial vibrating screen, an eccentric vibrating screen, a self fixed center vibrating screen and an electromagnetic vibrating screen. [1]

Linear vibrating screen

Vibrating screen is widely used in the industry of coal and other industries. It is used as a screening machine for classification, washing, dehydration and removal of materials. Among them, linear vibrating screen has been widely used for its advantages of high production efficiency, good grading effect and convenient maintenance. In the working process, the dynamic performance of the vibrating screen directly affects the screening efficiency and the service life.

[2]

Circular vibrating screen with tube type eccentric shaft vibration exciter and partial block to adjust the swing, the material screen drip line length, screen size, has the advantages of reliable structure, strong exciting force, high screening efficiency, the vibration noise is small, durable, easy maintenance and safety characteristics of circular vibrating screen is widely used in mining, product classification building materials, transportation, energy and chemical industry. According to material products and user requirements, high manganese steel braided screen, punching sieve plate and rubber sieve plate can be used. There are two kinds of sieve plates, one layer and two layers. All kinds of sieve plates can meet different requirements of sieving effect. The series of circular vibrating screens are mounted. The adjustment of the angle of the sieve surface can be realized by changing the position height of the spring support. [3]

Elliptical sieves

The elliptical sieve is a vibrating screen with elliptical motion track, which has the advantages of high efficiency, high screening precision and wide range. And the common sieve machine with the same specification



In comparison, there is a greater amount of treatment and higher screening efficiency. It is suitable for solvent of metallurgical industry, sieving of cold sinter, classification of ore in mine industry, classification of coal industry, dehydration and stripping, etc. It is an ideal substitute for the existing large vibrating screen and imported products abroad. TES three axis elliptic vibrating screen is widely used for screening of quarries and sand and stone. It can also be used for classification of products in coal preparation, mineral processing, building materials, construction, power and chemical industry.

Sieving principle: the power is transferred from the motor to the exciter, the active shaft and the gear vibrator (speed ratio is 1), and the three axes are rotated at the same speed, and the exciting force is generated. The exciter is connected with the high-strength bolt of the screen box to generate elliptical motion. Material on the screen with the screen machine high-speed elliptical movement, rapid stratification, screening, forward, and finally complete the material classification.

The obvious advantage of the TES series three axis elliptical sieves

The three axis drive can make the screen machine produce ideal elliptical motion. It has the advantages of circular vibrating screen and linear vibrating screen, and the elliptical track and amplitude can be adjusted. It can choose the vibration track according to the actual material condition, and has more advantages for difficult screening materials.

The three axis driven forced synchronous excitation can make the sieve get a stable working state, especially for the screening of large amount of screening.

The three axis drive improves the stress state of the screen frame, reduces the load of single bearing, uniformly forces the side plate, reduces the stress concentration point, improves the stress condition of the screen frame, improves the reliability and life of the screen, and establishes a theoretical foundation for the sifting of the sieving machine.

Because of its horizontal installation, it can effectively reduce the height of the unit, and can meet the needs of large and medium-sized mobile screen.

YK vibrating screen

YK vibrating screen

After arriving at the site, the equipment should not be placed on the ground directly. It should be placed smoothly on the flat sleepers, and the distance from the ground should not be less than 250mm. If stored in the open, should add anti cloth cover, to prevent the erosion of wind and rain. High frequency vibrating screen

High frequency vibrating screen is called high frequency screen for short, and high frequency vibrating screen (high frequency screen) is composed of vibrator, pulp distributor, screen frame, frame, suspension spring and screen.

High frequency sieves (high frequency sieves) have high efficiency, small amplitude and high screening frequency. High frequency vibration sieve principle and ordinary sieving equipment, due to the high frequency vibrating screen (high frequency screen) with high frequency, a failure of the pulp surface tension and fine material on the sieve surface high speed oscillation, accelerated the density usefulminerals andseparationeffect, increasing the probability of small in size separation material and sieve contact.

Advantage editing of vibrating screen

It mainly consists of a sieve box, a vibrator, a suspension (or a supporting) device and a motor, etc. Electric

Vibration sieve

Vibration sieve

Through a triangle belt drive spindle rotating exciter, as the exciter on the unbalanced centrifugal inertial force and weight, which was vibrating screen box. Different amplitudes can be obtained by changing the eccentric weight of the vibrator.

The main advantages of the vibrating screen:

1. Due to the strong vibration of the sieve box, the phenomenon of material blocking the sieve hole is reduced and the sieve efficiency and productivity are higher.

2. It is easy to construct simple and dismantle the screen.

3. The energy consumed by each ton of material is less.

Mechanical structure editing

The vibrating screen is usually composed of vibrator, sieve box, support or suspension device, transmission device and so on.


The vibrators of single axis vibrating screen and double shaft vibrating screen are usually divided into two kinds according to eccentricity reconfiguration.

Type. The configuration of eccentric weight is better with block eccentricity.

The screen box

The sieve box is composed of a screen frame, a sieve surface and a pressing device. The screen frame is made up of a side plate and a cross beam. The sifter must have enough rigidity.

Supporting device

The supporting device of the vibrating screen has two kinds of hanging type and seat type. The seat type installation is simple and the installation height is low, which should be preferred in general. The supporting device of the vibrating screen is mainly composed of elastic elements, which are commonly used as helical springs, plate springs and rubber springs.


The vibrating screen usually adopts the triangle belt transmission device. The structure of the vibrating screen is simple, and the number of the vibrator can be selected arbitrarily, but the belt slips easily when running, which may cause the screen hole to be blocked. The vibrating screen is also driven directly by a coupling. The coupling can maintain the stability of the vibrator, and it has a long service life, but it is difficult to adjust the number of the vibrator.

Work principle editors

The broken granular material groups with different size of particles are divided into a number of different levels through the uniform layer of single layer or multilayer screen. The particles larger than the sieve holes are left on the screen, which are called the sieves of the sieves. The particles smaller than the sieve holes through the sieve holes are called the sieves of the sieves. The actual screening process is: a lot of different size and thickness of mixed granular material into the sieve surface, only a portion of the particles and sieve surface contact, the vibration sieve box, the sieve material layer is loose, the large particle gap existed is further expanded, small particles to cross the gap and transfer to the lower layer or transport. Because the small particle gap is small and the large particles can not pass through, the original particle cluster with disordered arrangement has been separated, that is, the particle size is stratified, forming a rule of small particles below the coarse particles. The fine particles reaching the screen surface are smaller than the sieve holes, and the coarse and fine grain separation is finally realized, and the screening process is completed. However, the full separation is not, in the screening, there is usually a part of the sieves in the sieve. Although the particle size is smaller than the sieve hole when the fine particles are passed through the screen, they have different difficulty in sieving. The particles with similar size and sieve size are difficult to penetrate through the screen, and the particle clearance through the bottom surface of the screen is even more difficult.

Work feature editing

Firstly, the block eccentricity is used as the exciting force, and the exciting force is strong.

The high strength bolt is adopted in the screen box and the screen box. The structure is simple and the maintenance is convenient and quick.

The use of small amplitude, high frequency and large angle structure makes the machine with high screening efficiency, maximum processing, long life, low power consumption and low noise.

According to the structure and working principle of the screening machine, there are the following categories:

1. The working face of the roller screen is composed of a lateral rolling axis.

2. The working face of the roller screen is composed of a lateral rolling axis. The working part of the fixed sieve is fixed, and the material is sieved by the material slipping along the working face. Fixed screen is one of the more used in the concentrator, generally used for pre - screening of coarse or medium crumb. It is simple in structure and convenient in manufacture. The ore can be directly unloaded onto the screen without power consumption. The main disadvantages are low productivity, low screening efficiency, and generally only 50 - 60%.

3. The plane motion screen is a plane oscillating or vibrating in the plane. The plane motion is divided into linear motion, circular motion, elliptical motion and complex motion according to its plane motion. Shaking sieves and vibrating screens belong to this category.

Scope of application editing

The scope of application of vibrating screen is very wide, which involves almost all kinds of vibrating screens in all aspects of life in processing and manufacturing.

The vibrating screen is mainly used in mines, coal, smelting, building materials, refractories, light industry, chemical industry, medicine, food and other industries.

Function and principle:

The basic principle is to transform the rotary motion of motor into horizontal, vertical and tilted three dimensional motion by using the heavy hammer installed on the upper and lower ends of the motor shaft, and then transmit the movement to the screen surface. Changing the phase angle of the upper and lower weight of the hammer can change the direction of the moving of the raw material.

Start again after normal inspections of each vibration sieve nozzle blockage or fall off, always observe the temperature of the motor and sound, always observe the exciter sound, vibration sieve four observation angle amplitude is consistent with and without leaking coal belt is loose or fall off, often observe the dewatering effect of dielectric. Check whether the material is normal or not.

Shutdown: the material on the sieve can be stopped after the material is finished. At the time of parking, it is observed that the sieves collide with other equipment at the resonance point. When the following conditions are found, the sieves must be stopped immediately. When endangering personal safety or equipment safety, when the area of the screen area is large and the material is not smooth, the screen mesh will be broken in large area, the chute will be blocked up seriously, the screen box will be swaying badly and other abnormal situations. After the problem is removed, the vibrating screen can be restarted.
