Vibro Sifter Machine Principle
* Efficient Vibration Principle: By using an exciter (eccentric block or vibration motor) to generate a strong centrifugal force, the sieve box and screen mesh are forced to continuously vibrate. The material is thrown up and loose on the sieve surface, and particles smaller than the sieve hole quickly pass through the sieve.
* Optimize Motion Trajectory: Spiral diffusion of materials on the screen surface, with both conveying and screening functions, and a large processing capacity.
* Anti-blocking and Network Cleaning Technology: This is the key to ensuring continuous and efficient operation. Common techniques include installing elastic bouncing balls under the sieve or using ultrasonic-assisted cleaning devices to effectively reduce clogging.
* Modular and Durable Design: The screen box is connected by high-strength bolts instead of welding, which improves structural reliability and lifespan.
Using rubber springs or vomposite springs to reduce vibration and minimize impact on the foundation and operational noise.
The screen adopts a quick disassembly design, making it easy to replace.

Main Technical Features of Vibro Sifter Machine
Strong Excitation Force: Using block eccentricity as the excitation source, it has abundant power and is suitable for handling large amounts of materials.
Reliable Structure: The crossbeam and side plate of the screening box are connected by high-strength bolts without welding, with high overall strength and long service life.
Convenient Maintenance: The structure is simple, and key components (such as vibrators) can be disassembled and assembled as a whole, making maintenance easy.
Smooth Operation: Flexible connection with tire coupling and equipped with rubber spring vibration reduction, low noise and minimal dynamic load on the foundation.
Efficient and Eergy-saving: Adopting a small amplitude, high frequency, and large inclination structure, the screening efficiency is high, the processing capacity is large, and the power consumption is low.
Applications of Vibro Sifter Machine

The vibro sifter machine is particularly suitable for screening dry powder or granular materials, and is widely used in the following industries:
* Food Industry: Sugar powder, starch, salt, rice flour, milk powder, soy milk, egg powder, soy sauce, juice, etc.
* Chemical/Pharmaceutical Industry: Resin, paint, industrial medicine, cosmetics, paint, Chinese medicine powder, etc.
Note: The materials listed above are typically granules or powders with low moisture content and low adhesion. For materials with high viscosity, a tendency to clump, or requiring extremely high hygiene standards, more specialized vibrating screens (such as ultrasonic vibrating screens) may be required.
