The motion track of the vibrating dewatering screen is a straight line, which is produced in accordance with the standard of JB2444-86 “ZSM-type dual-shaft vibrating screen for coal”. There are 16 specifications in the whole series, which can be used for coal preparation, mineral processing, electric power, sugar, etc. Industrial departments such as salt production conduct dry and wet classification, dehydration, de-intermediation, and de-sliming of medium and fine-grained materials. The screening machine has large processing capacity and high screening efficiency.
Scope of application
The high-frequency vibration dewatering screen has four specifications. It can be used for coal preparation, ore beneficiation, Power, sugar, salt and other industrial sectors carry out dry and wet classification, dehydration, de-intermediation, and de-sliming of medium and fine-grained materials. The screening machine has large processing capacity and high screening efficiency.
The high-frequency dewatering screen is the recommended equipment for coal slime dewatering operations. It is widely used in coal slime recovery, filter press and coarse filtration, and other extremely fine materials such as dehydration and recovery. It 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 the belt coupling to operate synchronously and reversely. The centrifugal force produced by the two sets of eccentric masses is superimposed along the vibration direction, and the reverse centrifugal offset is counteracted, thereby forming a single excited vibration along the vibration direction. , Make the screen box do reciprocating linear motion.
1. The whole screen is installed horizontally, but the screen is installed at a negative angle to ensure the effect of forced dehydration;
2. The screen can choose stainless steel composite screen, tensioned installation, or stainless steel welded seam screen, compact installation, to meet different needs;
3. The vibration frequency can be adjusted at any time through the inverter to achieve the best dehydration effect;
4. The vibration is excited by a self-synchronizing liquid lubrication vibrator. The screen frame is made of special noise-reducing materials and connected with high-strength bolts to ensure the reliable operation of the screen and the reduction of operating noise. Compared with similar screens, the reduction is about 15DB;
5. The arc screen surface is set in the feeding section to improve the dehydration efficiency;
6. Set up a feeding box to ensure that the material is evenly fed into the screen surface;
7. Equipped with an integral chassis for easy handling and installation;
8. Rely on the filter layer on the sieve to retain fine particles and backlog for dehydration.
