Vibrating Feeder

Introduction of Vibrating Feeder

Vibrating feeder is a type of equipment used to transport and feed bulk materials into a production process. It utilizes vibration to move materials along a designated path, typically into hoppers, chutes, or other equipment.

Vibrating feeders use electromagnetic or electromechanical drives to produce vibrations. This motion helps to move materials smoothly and consistently, and the feed rate can usually be adjusted by varying the amplitude and frequency of the vibrations to precisely control the flow of material.

Types of Vibrating Feeder

There are primarily two types of vibrating feeders:

1. Electromagnetic Vibrating Feeders: They use electromagnetic coils to generate vibrations. The vibration frequency and amplitude are precisely controlled. They are very suitable for handling delicate materials and are often used in the pharmaceutical and food industries.

2. Mechanical Vibrating Feeders: They use eccentric motors to generate vibrations. They are used to separate and screen materials before they enter the primary crusher. They are designed to handle large pieces of material with high impact loads. They are more rugged than electromagnetic feeders and are very suitable for heavy-duty applications. They are often used in the mining and construction industries.

Motor vibrating feeder and electromagnetic vibrating feeder are two common vibrating feeding equipments, they have some differences in working principle, structure, performance and so on.

Difference Mechanical Vibrating Feeder Electromagnetic Vibrating Feeder

Working principle	Motor eccentric force	Electromagnetic force
Structure	Simple	Complex
Vibration frequency	Fixed	Adjustable
Vibration amplitude	Large	Small
Control accuracy	Low	High
Maintenance cost	Low	High
Scope of application	Large flow, coarse-grained materials	Fine materials, high-precision control

Tips:

If the material flow is large, the particle size is coarse, and the control accuracy requirement is not high, you can choose a motor vibrating feeder.

If the material is fine and the flow control accuracy requirement is high, you can choose an electromagnetic vibrating feeder.

Vibrating Feeder Working Principle

The workflow of a vibrating feeder usually includes the following main steps:

1. Material preparation: The material is conveyed from the storage device (such as a silo or bucket) to the feed port of the vibrating feeder.

2. Vibration drive: The vibrating feeder generates vibrations through electromagnetic or electric vibrators. This vibration causes the material to move in a certain direction in the trough of the feeder.

3. Material flow: Due to the effect of vibration, the material is pushed in the feed trough to form a uniform flow. The frequency and amplitude of the vibration can be adjusted to control the flow rate of the material.

4. Quantitative feeding: The vibrating feeder can achieve quantitative feeding of materials by adjusting the intensity and frequency of vibration to ensure a stable material supply to downstream equipment.

Features and Benefits

1. Using the principle of self-synchronization of vibration motor, it has stable operation, rapid starting, balanced parking, low noise and low energy consumption.

2. It is suitable for block, granular or powdery materials, the feeding particle size is 120~360mm, and the output can reach 40~600 tons/.

3. The material jumps forward continuously according to the parabolic trajectory, so the feed trough wears less.

4. The exciting force can be adjusted, the flow can be changed and controlled at any time, and the adjustment is convenient and stable.

5. Adopt closed structure body to prevent dust pollution.

5. This series of motor vibrating feeders are not suitable for occasions with explosion-proof requirements.

Structure of Vibrating Feeder

The structure of a vibrating feeder usually consists of the following main parts:

1. Feed trough: used to carry and convey materials, usually made of wear-resistant materials, and can be flat or V-shaped.

2. Vibration device

Electromagnetic vibrator: uses electromagnetic force to generate vibration, suitable for small and medium-sized feeders.

Electric vibrator: uses an electric motor to drive an eccentric wheel to generate vibration, suitable for most applications.

3. Support frame: provides stable support, usually made of steel, to ensure that no displacement occurs during vibration. Springs are used to isolate vibration, reduce the impact on the support structure, and ensure the stability of the equipment.

4. Control system: adjusts the vibration frequency and amplitude to achieve precise control of the material flow rate.

How to Choose Vibrating Feeder?

1. Material characteristics:

Particle size: The particle size directly affects the structural design and vibration frequency of the vibrating feeder.

Density: The material density affects the conveying capacity and driving power of the feeder.

Humidity: Materials with too high humidity may stick to the trough, affecting the smooth feeding.

Abrasiveness: Materials with strong abrasiveness have higher requirements for the material of the trough.

Breakability: Materials that are easily broken need to choose a feeder with a smaller vibration amplitude.

2. Conveying capacity: According to the needs of the production line, determine the amount of material that needs to be conveyed per hour. Excessive or too small conveying capacity will affect production efficiency.

3. Feeding accuracy: For production processes with higher requirements, it is necessary to select a vibrating feeder with high feeding accuracy. Feeding accuracy is related to factors such as vibration frequency, amplitude, and trough structure.

4. Working environment:

Temperature: High or low temperature environments may affect the performance of the equipment.

Humidity: High humidity environments may cause equipment corrosion.

>Dust: Dust environments require equipment to have good sealing.

>5. Installation space: Determine the installation size and location of the vibrating feeder based on the actual situation on site.
