Vibrating screen: the principle of action, dignity and features of choice

For the processing of large stones and crushed stone, special equipment is used, which has a loud name - a roar. It is very effective, as it can grind the presented natural material. A vibrating screen is especially often used.

What is this unit and where is it applied?

The presented equipment is crushing. Most often it is used in the mining industry and in construction. Vibrating screen is used for crushing, sifting and sorting of stones and other bulk materials. Most often, the equipment is used to separate them into fractions. With the help of the screen you can also separate ore materials from non-metallic materials, and also free them from excess moisture. During operation, the device emits a loud noise, so it got its name.

This machine can be used alone or as an element of large processing units. In addition, these devices can be mobile or stationary.

The operating principle of the apparatus

Features of the operation of such an aggregate, as a vibrating screen, are clear even to a professional. The eccentric of the vibrating screen is fixed on the loading part of the box. Thanks to a powerful engine, it can rotate. In this way, the loading part makes circular horizontal movements.

The material that pours out on the screen is evenly distributed throughout its surface. At this time, the particles are screened out through holes of a given size. During operation, the screen is periodically thrown. This action is accompanied by a corresponding shock noise. Thanks to tossing the material is better sieved.

Vibrating screen can be adjusted. That is, the vertical movement of the screens is tuned. This function allows to ensure high accuracy of sieving. The material is evenly distributed.

Functional and structural features of the apparatus

The design of the presented device is quite simple. It consists of a box in which there are frames, a vibrator and a drive that starts the whole apparatus.

Now let's look at the functionality of the unit. It should be noted that the modern vibrating screen for crushed stone is controlled by a small chip and a control panel. In addition, the device is equipped with an effective system to protect against voltage surges. Some models can store up to 9 work programs. There are screens that are additionally equipped with the function of the author.

Advantages of the presented equipment

This unit has certain advantages.

1. Stability. The roar will not turn over, even if during the work it experiences the greatest load.
2. Qualitative sieving of the material.
3. The possibility of choosing the size of the holes of the screen, which allows you to get the necessary fraction of stone or other bulk agents.
4. Economical. The frequency of the oscillations does not depend on the frequency of the network.
5. Ease of management. To adjust the work, a special panel is used.
6. Some models have a reduced noise level.
7. Lifetime.
8. High efficiency.
9. Good performance.

Features of device selection

In order for your stone crushing equipment to work as efficiently as possible, it is necessary to choose it correctly. To do this, it is desirable to be guided by certain parameters. For example, first pay attention to the power of the device. It depends on how much material you will need to process daily. The more it is, the higher the power will be required. The same rule applies to the size of the screen.

During the purchase, you should pay attention to the dimensions of the cells and other parameters of the shaker. The fact is that these properties determine what materials you will process, and also on what factions you can dissipate them.

Naturally, before buying, you need to make sure that the device is properly assembled. That is, he should not have a production marriage or any other defects. In addition, all parts must be well fixed. As for the material of manufacture, it is desirable to choose aggregates made of very strong alloys that will not be broken by a stone after a year of use. It is best to look at the certificates accompanying the selected product.

Now decide on where exactly you will use the presented device. If you do not intend to move it from place to place, then you are well suited to a stationary model. Otherwise, it is better to pay attention to the mobile vibrating screen that can be transported.

Well, another important issue is the cost of the equipment. It depends on all the above characteristics, as well as additional functions that the device can perform. Vibrating screen, the price of which on average is 4-5 thousand dollars, can be purchased in large shopping centers or specialized points of sale.
