Dewatering screen, also known as high-frequency dewatering screen, changes the water tension on the surface of the slurry through the exciting force. The slurry water passes through the screen and becomes undersize material, while the fine materials are blocked by the screen to form a filter layer and move forward under the influence of the vibration force.
The dewatering screen is mainly used for tailings dehydration in the ore dressing industry, coal slime dewatering in the coal preparation plant, dehydration of washed quartz sand and ceramic slurry, as well as dry and wet classification, dehydration, de-medium and desliming of medium and fine-grained materials in electric power, sugar making, salt making and other industrial sectors.
This kind of screening machine can choose vibration motor or exciter as vibration source.
1. Adopt vibration motors or electromagnetic vibrators or seat type vibration exciters as the vibration source to ensure 24 hours stable and continuous operation.
2. The screen machine beam and screen box are connected by high-strength bolts, without welding.
3. It adopts rubber spring support and vibration isolation, noise less than 75 dB, smooth operation.
4. Optional polyurethane sieve plate and stainless steel slotted screen.
5. Good dehydration effect, large processing capacity, long service life, single layer or double layer available.
6. Simple and compact structure, high rigidity and strength, balanced force distribution, and reasonable vibration parameters.
The dewatering screen adopts dual-motor self-synchronization technology, universal eccentric block and adjustable amplitude vibrator. It is mainly composed of screen box, vibration exciter, supporting system and motor. Two unconnected vibrators are driven by a soft connection or universal coupling for synchronous and reverse operation. The centrifugal force produced by the two groups of eccentric masses is superimposed along the vibration direction of the component, and the reverse centrifugal offset is offset, thereby forming a single excited vibration along the vibration direction, which makes the screen box move back and forth in a straight line.
