Double-layer complex screen

Product overview of Double-layer complex screen:

Double-layer complex screen is mainly used in the desulphurization system of power plant, in the flux screening system of steel plant, in the gravel aggregate system of construction industry,etc.

Double-layer complex screen we research and developed is basing on our High Frequency Screen, and it is with the character of a low-amplitude but a high-frequency. It is especially. It is especially for the separating of fine material which is less than 5mm.

Product features of Double-layer complex screen:

1. Double-layer complex screen changed the structure of the traditional vibrating screen sieve surface and screen box vibration, using multi-independent sieve surface vibration, sieve box and rack do not vibration movement.

2.Each section of sieve plate independent vibration source, independent vibration. According to the size distribution of the material in the field, the size of the material, the amplitude and the vibration frequency of each sieve surface can be adjusted adaptively to achieve the best combination of processing capacity and screening efficiency.

3. Less moving parts, the vibration quality is reduced and the power is small.

4. Screen box does not participate in vibration, so it is easier to achieve a fully enclosed structure, so that dust does not leak to meet the higher environmental requirements.

5. Sieve plate mainly used grizzly, comb, round steel welding, steel punching and so on.

Advantage of Double-layer complex screen:

1. The most advanced sieve concept, unique sieve structure.

A. By segment control, to achieve the sieve plate variable frequency, variable amplitude, variable trajectory movement, to achieve the purpose of efficient screening.

B. The use of patent sieve plate, a single sieve plate above the different frequency of loading, plugging the chance to reduce 80%.

2.Super environmental protection.

A. Double frequency only sieve plate vibration, sieve body does not vibrate, and truly achieve a full static seal, the structure of the sieve inside the formation of negative pressure, no vent point, the dust does not leak.

B. Double frequency screen sieve box to increase the internal walls of special insulation materials, compared to the traditional grizzly screen and elliptical screen can effectively reduce the noise 6-10dB.

3. super energy-saving.

Under the conditions of the same industrial and mining conditions, the weight of the compound frequency sieve is only 1/5 of that of the traditional elliptical sieve and 3/5 of the grizzly screen, so the double frequency screen is more than 1 times than the traditional oval sieve 1/3.

4. Ultra-high screening efficiency, large processing capacity.

The single-layer double-surface sieve perforation rate can reach 40%, through the frequency, amplitude and other means to improve the effective screening efficiency of 90%.

5. Super easy to maintain.

Double frequency screen using the overall replacement of the method, the replacement of a sieve 2 individuals only 2 hours will be able to resume production use, maintenance is simple, low-cost time.

6. Minimize construction costs.

Double frequency screen adopts the sectional vibration mode, which is 2 - 3 times of the normal dynamic load when starting and stopping. It greatly reduces the cost of the infrastructure construction and has obvious economic benefits.

7. The minimum spare parts consumption.

Double frequency screen bearing with Self-circulation cooling system, the exciter temperature can be controlled within 65 degrees, the bearing life is more than three times the traditional screen, the only oil required for the traditional screen sieve One-tenth of the machine.

8. The most complete combination.

According to customer requirements on the size of the material used in a variety of combinations, such as V-shaped, eight-shaped, laminated, etc. For viscous water-containing materials using multi-channel thin layer screening. For large capacity, double frequency granularity thickness probability screening principle, a variety of combinations to meet customer needs.

Applications of Double-layer complex screen:

Double-layer complex screen Mainly used in iron and steel enterprises solvent screening system (metallurgical industry sintering, blast furnace trough, coking, raw materials, etc.) and gravel aggregate system of construction industry. Using low amplitude, high frequency and other characteristics, for less than 5mm fine material screening is more excellent, but also to other industries, mainly for dry material screening. The sieve plate mainly bar, comb teeth, round steel welding, punching and so on.
