Profile

The ellipse uniform-thickness vibrating screen is a kind of vibration screen that it makes a ellipse motion orbit, which has following advantages, such as efficient, high precision of screening and wide applicable and other advantages.

Comparing with the the same specification common screening machine, it has a larger handling capacity and more high-efficiency screening. It is suitable for screening the solvent, sinter in cold condition in metallurgic industry and mineral classification in mine industry, classification, dehydrate and de-medium in mining industry. It is an ideal replaced product to replace present large vibration screen and foreign introduced product.

The ellipse uniform-thickness vibrating screen is mainly made up of straining box, exciter, vibration isolation system, gearing device, deck base with road wheel and other parts. Mostly of the snifter is dual-layer. The structure of the sieve plate is made of cast steel and adopts broach sieve plate. Also, the various sieve plate can be adopted in according to the requirements of the user.

Structural features

It applies the three-phase screen surface design to form the uniform-thickness screening layer.

The materials flow velocity is stable and uniform with high screen efficiency.

It applies three-axis driving and forced synchronous vibration principle to make the stable operation.

There are multiple screen plates for selection.

It is equipped with secondary vibration isolation system to alleviate the foundation load.

The inspection of the screen before the starting:the following items should be inspected.

Firstly, the sanitation should be inspected. Checking all of the connecting bolts to assure whether if they are completed,fastened and intact. Then the exciter should be check to assure that whether if it is intact. Checking the spring vibration aims to assure that whether if there exists no damage, lack, breakage and other phenomenons. Checking the triangular belt aims to assure whether if it is tense and whether if it is in of breakage. Checking the straining box and sieve plate aims to assure whether if it is damaged. Checking the sieve plate aims to assure that whether if it is blocked by the sundries. And the surface of the sifter must be smooth without loose and damaging phenomenon. Checking the inlet and outlet chute aims to assure that whether if it is available. Checking the cross beam aims to assure whether if there exists snap phenomenon. Checking the protective device aims to assure whether if it is reliable and safe. Checking the controlling box, communication and light aim to assure whether if it normal. Checking the ground connection aims to assure that whether if it is reliable and whether if the control buttons are flexible and safe.

Starting: when the vibration screen is started, the operator should stand by the vibration screen to monitor the starting of the machine, which aims to assure whether if there exists abnormal phenomenon. If it does, the machine must be stopped immediately. When the vibration screen is started normally, the operator should patrol all the nozzles on each vibration screen to assure whether whether if it is blocked or it falls off. The operator should often check the the temperature, sound of the machine and vibrator. Observing the vibrated condition aims to assure whether if the vibration in four corners are in the same frequency and whether if there exists coal leakage and loose triangular belt phenomenon. Always, the effectiveness of dehydrate and de-medium. Checking the condition of the inlet and outlet phenomenon of screen aims to assure whether if it is blocked or normal.  

Halting:after all of the materials in the screen have been ejected, the vibration screen can be halted. The operator should observe the screen to check whether if it will clash with other equipment when it go through the point of resonance during halting. When it happens, the machine should be halted immediately. When the machine will jeopard the safety of the operator and machine, or the the area of the screen is stacked with much sundries,or the feeding is not successful, or the screen is damaged serious, or the chute under the screen is blocked seriously, or the straining box shakes violently and or abnormal phenomenons, the fault should be excluded firstly and then restart the system of vibration screen.

FAQ:

What’s the meaning of the ellipse uniform-thickness in the ellipse uniform-thickness vibrating screen?

Ellipse means that the ellipse uniform-thickness vibrating screen adopts three sets of vibrator devices. The material in the ellipse uniform-thickness vibrating screen will make a ellipse motion. Thus, it is named as ellipse vibrating screen. Why it is named as uniform thickness is that each zone for stacking the materials has the same thickness. It can be called as the the same thick material layer. This model has the highest screening efficient by vibration. It has the greatest performance.

What pattern do the scale board adopt?

There exists various models can the scale board adopt, such as molten plate, PU plate and wear-resisting steel plate.

Generally, what type do the vibrator adopt?

The vibrator will adopt box-type vibrator, which is convenient to maintain and install.
