High-frequency dewatering screen is an advanced solid-liquid separation equipment, which is widely used in mining, building materials, coal preparation, hydropower and other industries. It is particularly suitable for dehydration, de-mediation or desludging of medium and fine-grained materials.
Working principle of high-frequency dewatering screen
The working principle of
high-frequency dewatering screens is mainly based on high-frequency vibration. After the equipment is started, the vibration motor generates high-frequency vibration to drive the solid particles on the screen plate to produce relative movement. Since the screen has different aperture sizes, the solid particles will be divided into particles of different sizes. Particles smaller than the aperture of the screen (such as muddy water) will be discharged through the screen hole, while particles larger than the aperture of the screen will be blocked above the screen, thereby achieving the purpose of solid-liquid separation. In addition, the high-frequency dewatering screen also adopts anti-blocking technology, which effectively avoids the adhesion and blockage of fine particles and ensures the screening effect.
Structural composition of high-frequency dewatering screen
The high-frequency dewatering screen is mainly composed of a screen frame, exciter, support system, screen plate, screen and motor. Among them, the vibration motor is used as the excitation source, which is installed on the outside of the screen frame, driving the exciter to provide huge excitation force, and driving the screen frame to perform periodic reciprocating motion along a straight line. This movement mode makes the material on the screen jump from the feed end to the discharge end gradually and achieves screening and dehydration during the jumping process.
Technical features of high-frequency dehydration screen
1. Advanced structure: The high-frequency dehydration screen has a reasonable structure, unique and novel, and adopts a new type of vibration motor as a direct drive, with small size, light weight, high efficiency and low noise.
2. Durable screen: The screen structure is simple and easy to maintain. High-strength metal mesh or polyurethane mesh can be used, which is durable.
3. Flexible installation: The machine can be installed in both stand-up and hanging styles to adapt to different installation environments.
4. Excellent performance: high output, adjustable amplitude, stable operation, good dehydration effect, excellent continuous operation performance, continuous working performance, continuous working for 24 hours, and output of 100-350 tons per hour.
5. Wide application range: widely used in mining, building materials, coal preparation, hydropower and other industries, especially suitable for coal slime dehydration before the plate and frame filter press system.
Use conditions of high-frequency dehydration screen
• The vibration acceleration does not exceed 20g (g is the acceleration of gravity).
• The ambient temperature does not exceed 40℃. If it exceeds 40℃, the power should be reduced.
• The altitude does not exceed 1000 meters. If it exceeds 1000 meters but does not exceed 4000 meters, the temperature rise limit should be reduced by 0.5℃ for every 100-meter increase.
• The power supply needs to be three-phase 380V and the frequency is 50Hz.
• The use environment should be free of conductive dust, and flammable, explosive and corrosive gases.
Application fields of high-frequency dewatering screen
High-frequency dewatering screen is mainly used for tailings dewatering in the mineral processing industry, coal slime dewatering in coal preparation plants, water-washed quartz sand dewatering, and ceramic mud dewatering, as well as dewatering, screening, desludging, and de-medium of medium and fine particles in industrial sectors such as electricity, sugar and salt making.
High-frequency dewatering screen plays an important role in many industries with its high efficiency, durability and flexibility. With the continuous advancement of technology and the continuous expansion of application fields, the performance and application scope of high-frequency dewatering screen will be further improved.
