All about mobile screens

After reading this article, you can learn everything about mobile screens. There are various Russian-made washing models. It is necessary to pay attention to caterpillar and wheeled devices, primary and sorting machines.

Almost all people interested in technology have long known that screens are These are devices for sorting bulk solids by means of a grid. The system works thanks to a special drive. The mobile screen is successful in sorting rocks. It is worth considering that such a system does not produce any crushing: it is limited to clean sorting.

The very essence of the device, as already noted, implies the performance of sorting operations. Not a single quarry production of mineral raw materials is complete without them. Modern mobile screens are useful not only for the extraction of minerals. They are used by:

• at metallurgical plants;
• at waste processing plants;
• in agricultural production.

There is a division according to the size of the sorted mass. The primary screener handles coarse lumps with confidence. Secondary machines are mainly designed to handle rock that has already been crushed. The amount of screening is determined by the size of the mesh in the sieve. Primary models are usually more robust and heavier in design.

Primary screens are used when:

• initial separation of the sand and gravel mixture;
• work with muddy rocks;
• sorting dolomite, diabase, granite or limestone;
• sorting of construction waste and sand.

Secondary screens allow you to disperse different rocks and materials up to 10 cm in size. The bunker, where the sorted rock will be poured, is covered by a grate. Very large particles will not get there at all, but will immediately roll off the surface of the grate and will be stored near the bunker.

Mobile screens can be wheeled or tracked. The use of wheels makes the machine lighter. At the same time, its maneuverability is significantly increased. However, the models on tracks are not so demanding on the parameters of the external environment. Therefore, they are excellent for use directly in mining quarries.

It should be noted that mobile-type primary washing screens have not yet been developed.... However, they are presented in the secondary segment. As for specific modifications, among them stands out Power Screen Warrior 2400. This device is tracked and has excellent performance. It should be noted that the Power Screen Warrior 2400 carries significant loads and allows the use of a wide range of sieves.

Sandvik QA451 - unique device. He has 3 decks and 2 sections, and there is no equal to him in this indicator. The system is capable of processing up to 600 tons in 60 minutes. Its own weight is 34 tons.

But the options do not end there. Is there some more:

• Lokotrack ST 2.8 (separating screening materials and equipped with a 9 cubic meter hopper);

• Mobiscreen MS 953 EVO (a system capable of processing up to 500 tons of rock per hour using bunkers with a volume of 8 or 10 cubic meters);

• Russian-made apparatus "UMS-400" from "Drobmash" with a decent outboard performance.

The key selection criteria are:

• total productivity;
• Processing efficiency;
• dimensions of materials;
• type of applied vibrations;
• vibration frequency;
• the number of tiers on which the material is sieved;
• cell geometry;
• total dimensions of the screening surface.
