Sandreck’s vibration feeder machines are designed for ultra-heavy-duty applications. They suit primary crushers—such as jaw, impact, and hammer crushers—and are widely used in the stone processing, construction materials, and metal mining industries. They feature a low installation profile and require minimal space. The series offers a maximum processing capacity of 1,200 TPH, handles a maximum feed size of 1,500 mm, and comes with a standard hopper capacity of 25–45 m³.

These vibrating feeders are characterized by reliable operation, low noise, and low energy consumption. They prevent material surging, offer a long service life, and are easy to maintain. Additionally, their lightweight, compact design makes installation and adjustment easy, ensuring excellent overall performance.

Vibration Feeder Working Principle

The core operating principle of a vibratory feeder machine uses eccentric blocks in a vibrator or an electromagnetic exciter to generate a periodic exciting force, causing the material trough to vibrate back and forth along an inclined path. Under the combined effects of this vibration and gravity, the material moves forward continuously along a parabolic trajectory, enabling uniform, metered, continuous conveyance.

• Mechanical vibration type: Rotating eccentric blocks generate centrifugal force, causing the screen box or trough to move in a circular or near-circular motion. As the trough moves, the material advances, being tossed forward along the inclined surface.
• Motor vibration type: A vibration motor serves as the excitation source, driving the trough to undergo periodic reciprocating vibration. This type suits industries such as metallurgy, coal mining, and construction materials.
• Electromagnetic vibration type: An electromagnetic coil generates a pulsed magnetic force when energized, causing the trough to vibrate at high frequencies. The material advances by hopping along the vibration line. The feed rate can be precisely controlled by adjusting the voltage or the thyristor conduction angle.

Features of Vibration Feeder Machine

1. Uniform Feeding: The vibration feeder uses vibration to move material along the trough via a parabolic trajectory or sliding motion, ensuring continuous, uniform transport.
2. Precise Flow Control: Feeding rates can be flexibly controlled by adjusting the vibration frequency or by installing a variable-frequency drive (VFD) motor.
3. Versatile Material Handling: Can convey materials ranging from 0.1 mm to over 1 meter, including high-temperature or corrosive materials.
4. Enhanced Production Efficiency: Reduces clogging in downstream equipment, improves crushing efficiency, and extends motor service life.
5. Auxiliary Screening: Certain models can perform coarse screening to separate out fines, thereby increasing overall output.
