What is the service life of the vibrating screen? What is the function of a vibrating screen?

In order to improve the service life of the vibrating screen, ensure the overall rigidity of the vibrating screen machine, and also consider that the materials can be quickly and evenly stratified and screened through the vibrating screen machine, Yaxin Vibrating Screen Company adopts a semi-double channel structure. That is, the range of the infeed section is a single-channel structure, and the screening section is a double-channel structure. Of course, when using the vibrating screen, we should also pay attention to the operation of the vibrating screen is very important, improper operation is likely to affect the service life of the vibrating screen, so what should we pay attention to when using?

1. Before starting, the operator should check the oil level height on both sides of the vibrating screen at the same time, the oil level is too high will cause the temperature of the exciter to rise or difficult to operate, and the oil level is too low will lead to premature damage to the bearing;

2. Check the tightness of all bolts, and re-tighten them once after the initial work for 8 hours;

3. Check the tension of the V-belt to avoid slipping during starting or work, and ensure the alignment of the V-belt wheel of the vibrating screen, and ensure the minimum gap between all moving parts and fixed objects;

4. The sieve should be started without load, and the feeding can only start after the sieve runs smoothly, and the feeding should be stopped before the shutdown, and the material on the screen surface of the vibrating screen should be discharged before stopping;

5. The feeding chute should be as close to the feeding end as possible, and the feeding should be evenly distributed along the full width of the vibrating screen as much as possible, and its direction should be consistent with the running direction of the material on the screen surface, so as to obtain the best screening effect;

6. The maximum drop from the feeding point to the screen surface is not more than 500mm, so as to ensure the minimum impact of the material on the screen surface of the vibrating screen;

7. When the exciter rotates in the direction of the material flow, the material running speed is increased, which can increase the production capacity, but reduce the vibrating screening efficiency;

8. When the exciter rotates against the direction of material flow, the running speed of the material is reduced, the production capacity is reduced, and the efficiency of the vibrating screen can be improved.

It should be noted that it should also be cared for and maintained during the usual use of the vibrating screen.

Oh, the service life of the vibrating screen is related to the user and usual maintenance, generally not less than 2 years.

The main functions of the vibrating screen:

The vibrating screen works by using the complex rotation vibration generated by the oscillator excitation. The upper rotating weight of the oscillator makes the screen surface produce plane gyratory vibration, and the lower rotating weight makes the screen surface produce cone rotary vibration, and the effect of its combined action makes the screen surface produce compound rotation vibration. Its vibration trajectory is a complex spatial curve.

The curve is projected as a circle in the horizontal plane and an ellipse in the vertical plane. The amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. Adjusting the spatial phase angle of the upper and lower hammers can change the curve shape of the motion trajectory of the screen surface and change the movement trajectory of the material on the screen surface.

Classification introduction: Vibrating screening equipment can be divided into mining vibrating screens, light fine vibrating screens, and experimental vibrating screens according to their weight uses.

Mining vibrating screen can be divided into: high-efficiency heavy-duty screen, self-centering vibrating screen, elliptical vibrating screen, dewatering screen, circular vibrating screen, vibrating screen (4 sheets), banana screen, linear vibrating screen, etc.

According to the material running track of the vibrating screen, it can be divided into:

According to the linear motion trajectory, it is divided into: linear vibrating screen (the material moves forward on the screen surface).

According to the circular motion trajectory, it is divided into: the structure and advantages of the circular vibrating screen (the material moves in a circular manner on the screen surface).

According to the reciprocating movement trajectory: fine screening machine (the material does reciprocating movement forward on the drying surface).

Vibrating screens are mainly divided into linear vibrating screens, circular vibrating screens, and high-frequency vibrating screens. According to the type of vibrating screen, the vibrating screen can be divided into single-shaft vibrating screen and double-shaft vibrating screen. The single-shaft vibrating screen is to use single unbalanced heavy excitation to vibrate the screen box, the screen surface is tilted, and the movement trajectory of the screen box is generally circular or oval.

The double-shaft vibrating screen is a double unbalanced heavy excitation using synchronous re-rotation, the screen surface is horizontally or gently tilted, and the movement trajectory of the screen box is a straight line. There are types of vibrating screens, such as inertial vibrating screens, eccentric vibrating screens, self-centering vibrating screens and electromagnetic vibrating screens.

Quickly separate the materials you need, separate mixed materials of different sizes, and can separate liquids and solids to remove unwanted debris.

Large particles are screened. Just like a sieve, small particles leak down and are sieved layer by layer until they meet your requirements.

Quickly separate materials with different particles.

The vibrating screen is called the mud vibrating screen, also known as the oil drilling fluid vibrating screen, drilling mud vibrating screen, mud vibrating screen, oil vibrating screen, mud linear vibrating screen, etc., the mud vibrating screen is widely used in the field of oil drilling, it is the first stage of mud solid control and mud purification treatment equipment of the drilling mud solid control system, and it is also one of the most important solid control equipment in the drilling mud purification system, which is used to separate the large particles of drill cuttings contained in the drilling fluid. The treated drilling fluid containing smaller particles can enter the next level of solid control equipment for further processing, Zhengdao Energy mud vibrating screen has obvious advantages in the treatment of large displacement drilling fluid, the output of strong excitation force, through the efficient and rapid removal of a large number of solid phases, in the oil drilling mud solid control system, trenchless horizontal directional crossing mud purification system, shield slurry separation system, urban construction piling mud purification and separation and oilfield environmental protection waste separation and control technology and other fields have been widely used.

Classification of large and small particles;

Vibrating screen as an important screening equipment in the stone sand production line, the quality of the stone vibrating screen is very important, so the user must choose the right screening equipment when the stone vibrating screen equipment, if the quality of the selected stone vibrating screen is not good, it will reduce the production efficiency of the stone machine-made sand, and may even damage the stone vibrating screen. So what should be considered when buying a stone vibrating screen?

When the stone vibrating screen is working, the material and the screen surface do vertical movement with each other, so the screening efficiency is higher and the specific output is larger, and the production efficiency and screening efficiency of the stone vibrating screen are determined by the size of the sieve hole. The production efficiency depends on the length and width of the sieve surface, the larger the sieve hole, the higher the screening efficiency of the sieve surface. Users should purchase according to their own production capacity and the structural characteristics of the stone vibrating screen.

The properties of raw materials include the particle size distribution composition of the raw materials, environmental humidity, powder content and particle appearance. If the raw material of fine sand is large, the production efficiency of the vibrating screen is larger. When the ambient humidity of the raw material is high, in general, the screening efficiency is reduced.

Therefore, in order to improve the whole process of screening, you can choose the method of increasing the sieve hole or the wet screening test, when the sand content of the raw material is large, the wet screening test or early washing should be selected.

To a large extent, the larger the screen hole of the stone vibrating screen, the lower the screening efficiency and the higher the productivity. The symmetry of the feeder is of great practical importance to the whole process of screening. The inclination angle of the screening machine should be appropriate, and the amplitude and frequency of the stone vibrating screen should be related to the structural and physical properties of the vibrating screen.

Don't try to be cheap, but communicate more pre-sales. You can't sift anything, you can't cooperate. Be honest!

The factors that affect the service life of the vibrating section screen are mainly the following two aspects:

1. Equipment production standards: If the manufacturer produces according to the standard, the equipment will be more durable.

2. The use environment of the equipment: If the equipment is properly maintained after it is out of use, it can also extend the service life of the vibrating screen.

1. Before work, check whether the fasteners, connectors, vibrating wheels, tension springs, etc. of the vibrating screen are loose and cracked, and the electrical protection line should be intact. For the dust removal device and ventilation device of the powder, the test operation will be carried out after the static inspection is qualified.

2. In operation, when it is found that the debris needs to be sifted, the power supply must be cut off and then removed with tools. If the operator needs to enter the internal screening, someone must supervise it.

3. The ventilation and dust removal device must be kept intact in the process of powder vibration, particle classification and slag discharge. If there is a leak, it should be repaired in time, and it should not be operated with illness. The mud vibrating screen should prevent mud from splashing or running slurry, affecting the working environment, and should be repaired in time.

A small amount of mud and powder leaking into the working channel should be removed at any time.

1.Remove the transport fixed connecting plate;

2.Check whether the bolts and other fasteners are locked;

3.The vibrating screen will produce a large amplitude when it is opened and stopped, and a safe distance should be reserved around the vibrating screen.

Make sure the power supply voltage is 380v

Make sure that the ground is flat and not shaky.

Make sure the fixing bolts have been removed during shipping.

Make sure the fastener is locked.

When the user uses the vibrating screen for the first time due to improper operation caused by the production failure is not a few, if you master some more common sense before use will avoid the appearance of some problems, the workmanship requirements of the vibrating equipment are strict, because the vibration motor is started to drive the high amplitude movement of the whole screen body, all aspects of the vibrating screen are closely matched, and the user should master the following requirements:

1.The vibrating screen should be carefully read before use, such as: how to master the adjustment of the vibrating motor exciter, the correct connection of the forward and reverse rotation of the vibrating motor, the fixing of the screen and the screen frame, how to disassemble and install the vibrating screen, etc.

2.The three-dimensional vibrating screen should be removed before use, the support frame on the inside of the spring should be removed, the function of the support frame is to avoid damage caused by the left and right shaking of the screen body during transportation, if the support frame is not removed before use, the whole screen will form an integrated synchronous vibration, resulting in damage to the equipment.

3.Three-phase wire connection: vibrating screen for three-phase live wire without zero line, equipment operation should observe the direction of rotation of the vibration motor shaft, the direction and the bottom cylinder label arrow is consistent with the correct connection, if it is reverse rotation, the three-phase line should be replaced in time two phase lines can be solved.

4.Test materials: first open the stainless steel dust cover and then start the machine, put a small part of the material into the vibrating screen, observe the material on the screen to measure the direction of the discharge, the correct method is that the material is rotated from the middle to the outward diffusion state, such as the problem can be adjusted after the angle of the eccentric block of the vibration motor can be solved in time.

There is a specific operation method for eccentric blocks in the manual).

1. Daily maintenance:

1. Before starting: (1) Check whether the screen is damaged;

2) Whether each set of rings is locked.

2. When starting: (1) Pay attention to whether there is any abnormal sound;

2) Whether the current is stable;

3) Whether there is any abnormality in vibration.

3. After use: Clean up immediately after each use.

2. Regular maintenance.

Regularly check whether the screen and spring are fatigued and damaged, whether all parts of the fuselage are damaged due to vibration, and lubricating oil must be added to the parts that need to be lubricated.

I just had a similar question today, and I was forwarded to you.

As the saying goes: rely on the mountains to eat the mountains and rely on the water. This is not false at all, from the reform and opening up to the present, with the development of science step by step, the word ravine and ditch no longer seems to be a derogatory term.

On the contrary, many wealthy entrepreneurs have taken their money to invest in mines in the ravines.

Of course, today's mining is not as hand-screened and hand-screened as it used to be. Now everything is automated, everything is how to give power. So how to choose the powerful mining vibrating screen?

We will not repeat the structure of the vibrating screen in detail, it is nothing more than using a vibrating motor to excite, and then a rubber spring to reduce vibration, plus a high wear-resistant material made of sieve plate and sealed screen box and other components to form this screening equipment. Understanding its structure, then how we choose, we can choose the corresponding vibration motor and sieve plate according to the field we use. Generally speaking, the vibrating screen used in mining is mainly used in metallurgy, mining, coal, building materials, electric power, chemical and other industries, especially in the metallurgical industry.

Generally, according to your electricity environment and vibration needs, you can choose DC vibration motor, synchronous vibration motor or asynchronous vibration motor, and then choose the appropriate mesh screen, screen plate and screen box according to the size of your screening object. However, now the manufacturers of vibrating screens are more proficient than one another, as long as you say your use, they will tailor the right vibrating screen equipment for you.

If you want to do a good job, you must first sharpen your tools. In the same way, as long as you choose the most powerful vibrating screen, you can make your work handy, so as to achieve twice the result with half the effort!

It depends on what kind of vibrating screen you want, I believe that Xinxiang Kaixiang Machinery Company is your ideal choice.

To buy a vibrating screen, of course, you must choose a professional manufacturer, Xinxiang Machinery provides you with a complete set of screening process equipment, as well as related supporting products.
