Vibrating Feeder

In industrial production, the efficient and stable conveying of materials is the key to increasing production capacity. The VRV Industrial Vibrating Conveyor System is the best solution for handling bulk materials.

Vibrating feeder conveyor working principle

The vibrating feeder realizes material conveying based on the vibration principle. Periodic exciting forces are generated by vibration sources such as electromagnetic exciters and motor eccentric blocks, causing the feeding trough body to vibrate at a specific frequency and amplitude. The materials in the trough are affected by the vibration and move forward continuously in a jumping manner along the conveying direction. The feeding speed can be adjusted by regulating the vibration frequency, amplitude, or controlling the working time of the vibration source, so as to convey the materials evenly, continuously, and quantitatively to the specified position.

Vibrating feeder advantages

1. Simple structure. The core components of the vibrating feeder are only the vibrator and the conveying trough. The vibrator is used to generate the vibrating force, and the conveying trough is used to carry the materials. The vibrating feeder machine is more robust and durable. Even when operating 24 hours a day throughout the year, there is hardly any wear and tear. This greatly reduces the failure rate and downtime maintenance costs.

2. Uniform conveying and protection of material properties. The linear vibrating feeder uses the periodic vibration generated by the vibrator to make the materials in the feeding trough have small throwing and sliding movements, thereby realizing the conveying of the materials. This vibration method can form a uniform flowing layer of materials in the trough, avoiding the accumulation and blockage of materials. While ensuring the uniformity of material conveying, it also avoids the damage to the material properties caused by extrusion.

3. High sealing performance. The vibrating conveyor can adopt tubular and square enclosed designs. O-ring seals and steel joints are used at the entrances, exits, and the joints of movable components, thus having high sealing performance and avoiding dust pollution.

4. Convenient for observation and cleaning. The VRV Vibrating Feeder Manufacturer designs multiple observation holes and detachable covers on the vibrating feeder according to the customer's requirements, which is convenient for observing during material conveying and cleaning the equipment after long-term operation.

5. Wide range of applicable materials. The vibrating feeder can handle fine materials, powders, granules, and bulk materials of various sizes and properties, from milk powder and calcium carbonate to coal and ores.

6. High conveying accuracy and low noise. The VRV Electromagnetic Vibrating Feeder is driven by the VRV Electromagnetic Vibrator, which can achieve stepless speed regulation from 0 - 100%, start and stop immediately without delay, and the operating noise is below 80 dB.

7. Automated operation and control. The VRV Magnetic Vibrating Feeder can be controlled by the VRV Controller and integrated into the automated control panel, supporting analog remote control of the feeding speed.

8. Flexible structural design: Important parameters such as the material, length, shape, and conveying capacity of the vibrating feeder machine can be determined through joint discussions between the customer and VRV engineers.

Vibrating feeder structure

The biggest feature of structural vibration feeder compared to other feeding equipment is its simple structure, which makes it maintenance free and operates smoothly for a long time. Its main components include the following:

1. Vibration motor or electromagnetic vibrator: As the vibration source of vibration feeder, both vibration motor and electromagnetic driver have the characteristics of simple structure, high reliability, andeasy maintenance, and are widely used in vibration equipment such as vibration feeder, vibration screen, and vibration conveyor. Choose vibration motor or electromagnetic driver according to differentusage scenarios;

2. Controller: If an electromagnetic driver is selected as the vibration source, the controller will also become an essential component. Its main function is to adjust the vibration force and amplitude ofthe driver to achieve the best feeding efficiency;

3. Conveyor trough: The conveyor trough hasthe characteristics of diverse shapes, adjustable volume, optional materials, and anti clogging. Common types include groove and tube shaped, open andclosed. Different shapes of conveyor bodies can be customized to ensure smooth transportation of different materials;

4. Bracket or Hanging support: The spring bracket has the characteristics of vibration absorption and noise reduction, stable support, and easy installation, effectively extending the service life of the vibrating feeder.

Vibrating feeder application scenarios

1. Mining operations: Stable conveyance of large-sized materials

-- Case: A copper mine uses a heavy-duty vibrating feeder (feed inlet size: 800×1200mm), paired with a PLC intelligent control system, which increases the raw ore processing efficiency by 40% and reduces the equipment failure rate by 60%.

2. Food and pharmaceutical industries: Hygienic standards and refined requirements

-- Key indicators: Made of stainless steel 304/316, surface roughness Ra ≤ 0.8μm, detachable structure (meeting CIP/SIP cleaning requirements), suitable for materials such as flour and tablets.

3. Building materials and chemical industries: Special designs for corrosive / flammable and explosive environments

-- Anti-corrosion solutions: Lined with polytetrafluoroethylene (PTFE) or sprayed with epoxy resin to handle acidic and alkaline materials (such as sulfuric acid and caustic soda);

-- Explosion-proof design: Select Ex II BT4 explosion-proof motors to meet the explosion-proof requirements of chemical workshops.

4. Hardware fasteners: Close coordination of multiple devices

-- Operating results: A conveying production line composed of two or more feeders accurately and efficiently conveys fastener materials such as bolts, nuts, and cap nuts. Its robust structure and excellent conveying efficiency enable a conveying capacity of 500t/h while maintaining precise speed control.

5. Glass industry: Requirements for continuous and efficient conveyance

-- Industry needs: Glass factories have strict requirements for the conveyance of raw materials. Once there is a halt in a feeding and charging work process, it will affect the production progress of the entire production line. There are a wide variety of raw materials for glass production, such as quartz sand, soda ash, limestone, feldspar, etc. Each raw material has very different characteristics. Quartz sand has a relatively large particle size and a hard texture, while soda ash is powdery and highly water-absorbent. The vibrating feeder can easily handle these raw materials with different characteristics by flexibly adjusting the vibration frequency, amplitude, and inclination angle, preventing blockages, adhesion, or poor discharging, and ensuring a continuous and stable supply of raw materials.

6. Lithium battery chemical industry: High-precision conveyance of granules and powders

-- Equipment features: The compact and flexible design structure of the Electromagnetic vibrating feeder enables it to adapt to the high-precision and quantitative conveyance of chemical powders such as calcium carbonate, lithium carbonate, lithium iron phosphate, and emulsifier powder. The feeding accuracy is ±2%, and the production capacity is increased by 40%.
