Electromagnetic Vibrating Feeder

What is an electromagnetic vibrating feeder?

Electromagnetic vibrating feeder is a device used to precisely control the flow rate of granular materials. It operates on the principle of electromagnetic vibration, where an alternating current passes through a coil, creating a magnetic field that attracts and releases a magnetic plate. This periodic attraction and release generates a linear vibration, causing the material on the feeder tray to move forward in a controlled manner.

Our feeders are available in ten different models with capacities ranging from 25 to 100 tons per hour. They are available in SS 304/316L or mild steel. The chutes vibrate at 3000 times per minute and are able to handle a wide range of materials from the finest powders to large coarse particles.

Types of electromagnetic vibrating feeder

1.Different materials

Carbon steel: Q235 carbon steel trough is used, which is suitable for customers with low hygiene requirements, and the price is cheap.

Stainless steel: It is made of SUS304 stainless steel trough, which is resistant to corrosion, high temperature, not easy to rust, and can avoid the pollution of raw materials.

2.Different structure

Open type: It is a common structure. Suitable for material feeding without special requirements.

Enclosed type: Enclosed electromagnetic vibrating feeder adopts closed body design, which can prevent dust pollution. It is suitable for feeding materials with fragile particles, large dust and easy volatilization.

3. Different installation method

Seat type: Under normal conditions, it can be installed with a downward tilt of 10°. For materials with high viscosity or high water content or fine powder, it can be installed with a downward tilt of 15°.

Hanging type: Hanging type installation, the body performs periodic linear reciprocating motion along the groove direction to achieve uniform and quantitative feeding. After installation, the feeder should have a 20mm swimming gap, and the horizontal direction should be horizontal. The suspension device adopts flexible connection .

4. Different  trough:

Light groove type: suitable for feeding light materials with small specific gravity.

Flat groove type: suitable for uniform feeding of thin material layers.

Wide groove type: The double vibrating head design is adopted, which widens the width of the groove body, increases the particle size of the receiving material, and at the same time increases the feeding amount, which can send the entire receiving device (such as a belt conveyor or a crusher) to the whole receiving device. Cross-section uniform cloth. Mainly used for coal preparation, and can also be used to feed the screening equipment.

How do electromagnetic vibratory feeder works?

The Electromagnetic Vibrating Feeder working principle is based on electromagnetic vibration technology. When alternating current passes through the electromagnetic coil, it generates a rapidly changing magnetic field. This magnetic field attracts and releases the armature at high frequency, causing the feeder trough to vibrate continuously. The vibration force drives bulk materials to move forward along the trough in a stable and controlled flow. Because of its precise feeding capability, the Electromagnetic Vibrating Feeder is used in industries such as mining, metallurgy, coal processing。

Features and Benefits

The Electromagnetic Vibrating Feeder exhibits stable vibration parameters during material conveying, with an amplitude typically ranging from 1.5 to 3 mm and a vibration frequency reaching approximately 3000 times per minute. During operation, the material flow rate can be turned on, off, or adjusted via the control system, thereby altering the feeding speed. The controller employs a thyristor half-wave rectifier circuit, allowing for continuous adjustment of the feeding rate by regulating the thyristor opening angle during operation, facilitating unified management of the production line. The material, subjected to vibration within the feeding trough, is continuously thrown up and moves forward along a parabolic trajectory. This motion reduces wear on the trough surface, lowering maintenance and replacement costs. Utilizing the principle of mechanical vibration resonance, the dual-mass structure operates near resonance, finding applications in material conveying equipment, such as in the mining and building materials industries.

Structure of electromagnetic vibrating feeder

The Electromagnetic Vibrating Feeder consists of several components, including an electromagnetic coil, an armature, a feed trough, and a controller. When energized, the electromagnetic coil generates a magnetic field, causing the armature to reciprocate, which in turn drives the feed trough to vibrate continuously. The material moves forward along the feed trough under the influence of vibration, achieving stable conveying. The controller adjusts the vibration frequency and amplitude, controlling the material feeding speed by changing the current parameters.
