For processing large stones and rubble, special equipment is used, which has a loud name - screen. It is very effective because it can grind the natural material. Especially often used vibrating screen.
What is this unit and where is it used?
The equipment presented is crushing. Most often it is used in the mining industry and in construction. Vibrating screen is used for crushing, sieving and sorting stones and other bulk materials. Most often, equipment is used to separate them into fractions. With the help of a roar, it is also possible to separate ore materials from non-metallic materials, as well as free them from excess moisture. During operation, the device makes a loud noise, which is why it got its name.
This machine can be used independently or as an element of large processing plants. In addition, these devices can be mobile or stationary.
The principle of operation of the apparatus
Features of the operation of such an aggregate as a vibrating screen are not clear even to a professional. An eccentric vibrating screen is fixed on the loading part of the box. Thanks to a powerful engine, it can rotate. In this way, the boot part makes circular horizontal movements.
The material that pours onto the sieve is evenly distributed over its entire surface. At this time, particles are sifted through holes of a given size. During operation, the sieve is periodically thrown. This action is accompanied by corresponding impact noise. Thanks to the tossing, the material is better sifted.
Vibrating screen can be adjusted. That is, the vertical movement of the screens is adjustable. This feature allows for high sieving accuracy. In this case, the material is evenly spaced.
Functional and design features of the device
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 launches the entire apparatus.
Now we will understand the functionality of the unit. It should be noted that the modern vibrating screen for crushed stone is controlled using a small chip and a control panel. In addition, the device is equipped with an effective system of protection against voltage surges. Some models are capable of storing up to 9 work programs. There are screens that are additionally equipped with an auto-sifter function.
The advantages of the presented equipment
This unit has certain advantages.
- Sustainability. The roar will not roll over, even if it experiences the greatest load during operation.
- Quality sieving material.
- The ability to select the size of the sieve openings, which allows you to get the necessary fraction of stone or other granular materials.
- Profitability. The oscillation frequency does not depend on the network frequency.
- Simplicity of management. To adjust the operation, a special panel is used.
- Some models have reduced noise levels.
- Life span.
- High efficiency.
- Good working capacity.
Features of device selection
In order for your stone crushing equipment to work as efficiently as possible, you need to choose it correctly. To do this, it is advisable to be guided by some parameters. For example, first pay attention to the power of the device. It depends on how much material you need to process daily. The larger it is, the higher the power required. The same rule applies to the size of the screen.
At the time of purchase, you should pay attention to the cell sizes and other parameters of the vibrating screens. The fact is that these materials depend on which materials you will process, as well as on which fractions you can disperse them.
Naturally, before buying, you need to make sure that the device is properly assembled. That is, he should not have a manufacturing defect or any other defects. In addition, all parts must be well secured. As for the material of manufacture, it is advisable to choose units made of very strong alloys that will not be broken by stone after a year of use. It is best to look at the certificates accompanying the selected product.
Now decide on exactly where you will use the presented device. If you do not intend to move it from place to place, then the stationary model is perfect for you. Otherwise, it is better to pay attention to the mobile vibrating screen that can be transported.
Well, another important issue is the cost of equipment. It depends on all of the above characteristics, as well as additional functions that the device can perform. Vibrating screen, the average price of which is 4-5 thousand dollars, can be purchased at large shopping centers or specialized points of sale.
