Vibrating Feeder

What is a vibrating feeder?

Vibrating feeder, also known as a vibratory feeder or vibratory conveyor, is a device used to transport and feed bulk materials in a controlled manner. It utilizes vibrations to move materials along a trough or tube, ensuring a steady and controlled flow.

Vibrating feeders are widely used in various industries, including mining, construction, pharmaceuticals, food processing, and recycling. They are commonly used to feed bulk materials such as aggregates, ores, chemicals, powders, and granular materials.

Vibrating feeders offer several advantages, including precise and uniform material feeding, efficient material handling, and the ability to handle high-capacity loads. They are often used in conjunction with other equipment such as crushers, screens, and conveyors to form a complete material handling system.

Types of Vibrating Feeders

Types	Motor Type Vibrating Feeder	Electromagnetic Vibrating Feeder	Vibrating Tube Feeder
Application	Combined with motor vibration and mechanical vibration, it is rugged enough to handle heavy-duty applications.	Typically used in applications requiring precise feeding of small or delicate materials.	Typically used to transport fragile or fragile materials that could be damaged or degraded by other types of feeders.
Features	Trough widths range from 6 inches to 5 feet and conveying lengths can be up to 10 meters. Multiple machines can be used in series to realize long-distance transportation.	Using electromagnetic drive to generate vibration, precise and highly controllable, adjustable feed rate.	Seals up to 20 feet (6 meters) and can be cascaded up to 100 feet (30 meters).
Working principle	The motor drives the eccentric block to rotate, generating vibration, causing the hopper or trough to vibrate, so that the material is thrown up and falls from the feeding port to achieve feeding.	The electromagnet generates periodic magnetic force to drive the armature to vibrate. The vibration force is transmitted to the trough through the spring, causing the material to move along the trough.	The vibration of the vibrating tube causes the material to fall from the tube port to achieve feeding. The vibrating tube is usually vibrated by the motor driving the eccentric block or electromagnet.

What is the applications of vibrating feeder?

Vibrating feeders are used in a wide variety of industries where controlled and reliable material transfer is required. Here are some common applications for vibratory feeders:

Mining and Quarrying: For transporting and feeding bulk materials such as ore, coal, aggregates and minerals. They are used in primary and secondary crushing systems, storage and recycling processes.

Construction and Aggregates: Used on construction sites and aggregate processing plants for efficient handling and supply of construction materials including crushed stone, gravel, sand and concrete. They ensure a continuous, uniform supply of material to crushers, screens and other processing equipment.

Recycling and Waste Management: Used in recycling plants and waste management facilities to process and supply a variety of recyclable materials and waste. They help to separate and sort different types of materials such as paper, plastic, metal and glass, thereby increasing the efficiency of the recycling process.

Food Processing: For precise control of the feeding of ingredients, additives and raw materials. They are used in applications such as ingredient, mixing, packaging and delivery of food, ensuring accurate dosing and preventing product contamination.

Pharmaceutical and Chemical: For precise feeding of granules, powders and other bulk materials. They are commonly used in processes such as mixing, sieving and packaging of pharmaceuticals, chemicals and ingredients.

Foundries and Metal Fabrication: Foundries and metal fabrication plants use vibratory feeders to convey and feed raw materials such as castings, scrap metal, and metal powder. They help regulate material flow during casting, melting and forming.

Ceramic and glass industry: Vibrating feeders are used in ceramic and glass manufacturing to control the supply of raw materials such as powders and granules. They ensure consistent material flow during forming, molding and firing.

What is the function of vibrating feeder?

The main functions of the vibrating feeder are as follows:

Uniform feeding: It can evenly feed materials to crushers, screeners, conveyor belts and other equipment to ensure that subsequent processes can be carried out stably and efficiently. Uniform feeding can avoid equipment load fluctuations caused by uneven materials and increase the stability of equipment operation.

Continuous conveying: The vibrating feeder can realize continuous material conveying, avoiding low production efficiency and equipment idleness caused by intermittent feeding. Continuous conveying can ensure continuous operation of the production line and improve overall production efficiency.

Screening function: During the conveying process, the vibrating feeder can simply screen the material, remove fine particles or impurities, and ensure the quality of the material in the subsequent process.

Prevent blockage: The vibration of the vibrating feeder can prevent the material from being blocked during the conveying process, especially for sticky or wet materials, vibration can effectively prevent the material from adhering to the trough.

What is the working principle of vibrating feeder?

The feeding process of the vibrating feeder is realized by using a special vibrating motor or two motors to drive the vibrator to drive the feeding trough to vibrate periodically and linearly along the inclined direction. The material in the material is thrown up and jumps forward according to the trajectory of the parabola. The throwing and falling are completed in an instant. Due to the continuous excitation of the excitation source, the feeding trough vibrates continuously, and the coal in the trough jumps forward continuously, so that the achieve the purpose of feeding.
