Vibrating Feeder

What is Vibrating Feeder?

The vibrating feeder can evenly feed materials for the crushing equipment in the sand production line, and screen materials roughly. And also it can serve materials for belt conveyors, bucket elevator, screening equipment, crushing equipment and grinding machines.

A Vibrating Feeder, sometimes called a vibratory feeder, is industrial equipment to convey bulk materials over a short distance at a controlling rate. Think of it as a short, sturdy vibration conveyor with a motor that makes it shake. This controlled shaking action moves the material forward. This machine is a critical part of any feeder system, taking a large pile of material from a vibrating hopper and turning it into a consistent, predictable stream that other machines, like crushers, can handle efficiently.

What are Applications of Vibratory Feeders?

Mining vibrating feeder has a very wide range of use. This equipment applys in mining, metallurgy, coal, building materials, chemical industry, electric power and other industries. The following is the specific scope of use:

• In the mining industry, the mining vibrating feeder applys to convey raw ore from the excavation site to the crusher or screening equipment. Its efficient vibration mechanism can effectively separate and convey ores of various particle sizes and improve production efficiency.
• For the metallurgical industry, the equipment aims to feed lumpy, granular and powdery materials uniformly, continuously or quantitatively from storage silos or other storage equipment to the receiving equipment, in order to meet the needs of automatic batching, quantitative packaging and automatic control.
• In the coal industry, mining vibrating feeder can apply to evenly transport coal from the silo to the crusher or screening equipment to improve the efficiency of coal processing.
• In addition, mining vibrating feeder applys in building materials, chemical industry, electric power and other industries for conveying and processing various materials.

How Vibratory Feeder Work?

The working principle of the vibrating feeder is mainly to use the eccentric block in the vibrator to rotate to produce centrifugal force, so that the movable parts of the screen compartment and vibrator make a forced and continuous circular or nearly circular motion. This movement is transmitted to the conveying trough connected to the vibrating motor, so that the material is subjected to vibration force in the trough, thus generating sliding and dislodging, and realizing the uniform and continuous conveying of materials.

The machine consists of a trough or pan, which holds the material, mounted on flexible springs. A vibrator unit, which is either an electric motor with eccentric weights or an electromagnetic feeder drive, is attached to the pan. When you turn it on, it creates powerful, rapid vibrations. This motion moves the pan in a quick, repeated forward-and-up, backward-and-down cycle. Each tiny “throw” lifts the material and moves it forward, creating a smooth, continuous flow.

In addition, the mining vibrating feeder can also be adjusted by adjusting the phase and weight of the eccentric block to change the size and direction of the excitation force, so as to adapt to the changes in different materials and process requirements. This kind of adjustment is flexible and convenient, and can realize precise feeding control.

Why Use a Vibration Feeder in Material Handling Systems?

• Simple structure, easy maintenance: the overall structure of the equipment is compact, covers an area of small, easy to install, debugging, maintenance.
• Uniform and continuous feeding: by adjusting the excitation force and vibration frequency, it can realize the uniform and continuous conveying of materials and avoid the phenomenon of material blockage and accumulation.
• Strong adaptability: for ores or materials with different granularity and hardness, mining vibrating feeder can maintain good feeding effect.
• Energy saving and environmental protection: the equipment in the operation process of low noise, low energy consumption, in line with the requirements of environmental protection.
• High efficiency and durability: mining vibrating feeder is made of wear-resistant materials, long service life, stable and reliable operation, which can reduce the production cost.

Using a vibration feeder provides several major benefits for your production line. The most important advantage is flow control. You can precisely adjust the feed rate, ensuring downstream equipment runs at peak efficiency and protecting expensive machines from damage. They are also very reliable with low maintenance needs because they have few moving parts. A key advantage of the vibrating grizzly feeder is its ability to act as a pre-screener. It has parallel bars that allow smaller particles to fall through, removing fines before they even reach the crusher, which boosts the efficiency of the entire circuit.

What Materials Can Be Handled by a Vibrating Feeder in Mining Area?

A Vibrating Feeder is built to handle a very wide range of bulk materials, especially in tough environments. They are designed to move heavy, abrasive, and large-sized materials with ease. As a dedicated aggregate feeder or ore feeder, it handles:

• Aggregate: Crushed stone, sand, and gravel for construction.
• Ore: Iron ore, copper ore, gold ore, and bauxite from mining operations.
• Bulk Solids: Coal, coke, limestone, and other raw industrial materials.

The robust construction of this vibratory equipment ensures it can withstand the constant impact and wear from these tough materials.

What are the Key Components and Structure of a Vibrating Feeder?

A vibratory feeder has a simple and strong structure with three main parts. First is the feeder pan or trough. This is the heavy-duty steel body that holds and conveys the material. It is often lined with replaceable wear plates. Second is the vibrator. This is the “engine” of the feeder. It can be a mechanical unit with a motor and eccentric weights or a quieter electromagnetic drive. Third is the suspension system. This usually consists of heavy-duty coil springs that allow the pan to vibrate freely while supporting its weight and isolating the vibratory force from the support structure.

What are the Different Types of Vibrating Feeders?

There are two main types of vibrating feeders, categorized by their drive mechanism. The choice depends on your application’s needs for power and control.

• Mechanical Vibrating Feeders: These use a motor to spin eccentric weights, creating a powerful, fixed vibration. They are incredibly robust and are the best choice for heavy-duty jobs like feeding primary crushers with large rock. They are the backbone of most aggregate and mining operations.
• Electromagnetic Vibrating Feeders: These use a powerful electromagnet to create the vibration. They have no moving parts like bearings, so they require less maintenance. Their biggest advantage is very precise feed rate control. You can adjust the flow instantly and accurately, making them perfect for dosing and blending applications.

How to Choose Suitable Vibrating Feeder?

Choosing the right feeder machine is critical for your plant’s performance. You must consider several key factors to make the correct decision.

1. Material Properties: A key detail is your material’s “angle of repose”—the steepest angle it can be piled at without slumping. Sticky materials with a high angle of repose need a steeper feeder deck and more power. Free-flowing materials need a shallower angle to prevent flooding.
2. Capacity: How many tons per hour do you need to move? Always choose a feeder with a capacity slightly higher than your maximum requirement.
3. Application: Is it feeding a crusher or a screen? A heavy-duty grizzly feeder is needed for a primary crusher, while a lighter pan feeder might work for a stockpile.
4. Environment: A dusty, wet, or corrosive environment will determine the required motor enclosure and paint specifications.

How Much Cost of Vibrating Feeder Price?

The price of a vibrating feeder can range from a few thousand dollars to over $50,000 for a large, heavy-duty model. The cost depends on size, capacity, and drive type. However, beware of assuming all feeders are created equal. Cheaper models often have undersized vibrators and weak frames, leading to inconsistent feed rates and frequent breakdowns. It’s better to consider the total cost of ownership. Investing in a robust machine from a reputable feeder manufacturer like ZONEDING might cost more upfront but will save you money from lower energy use, less downtime, and a much longer service life.

General Specification

What are the Factors Affecting Vibrating Feeder Performance?

Several factors impact how well your material feeder works. The most critical is the material’s characteristics, such as moisture and stickiness. The feeder’s setup is also key. A crucial technical detail is the vibrator’s stroke angle—the direction of the vibration. A steeper stroke angle creates a more aggressive action, which is better for heavy or sticky materials. A shallower angle is gentler, suitable for fragile materials. Experimenting to find the optimal angle for your material is important for top performance.
