**Linear Vibrating Feeder Characteristics**  

**I. Structural Design Features**  
- **Dual Eccentric Shaft Vibrator**: Utilizes two eccentrically positioned shafts with meshing gears, driven by a motor to generate linear vibration force, ensuring efficient operation.  
- **Modular Components**: Compact and durable structure comprising a vibrating frame, springs, vibrator, motor vibration frame, and motor.  
- **Adjustable Grid Bar Design**: Features adjustable grid bar gaps to prevent material blockage, with multiple wear-resistant parts for extended service life.  

**II. Functional and Performance Advantages**  
- **Uniform and Continuous Feeding**: Forces material discharge via vibration, enabling consistent feeding of bulk or granular materials to prevent equipment malfunctions caused by uneven input.  
- **Coarse Screening Function**: Integrates coarse screening during feeding to separate fines, enhancing downstream crusher efficiency.  
- **High Processing Capacity**: Withstands large material impacts, offering a feeding capacity of 80–800 t/h for high-intensity production.  
- **Energy Efficiency**: Optional variable-frequency speed-regulating motor allows adjusting feed rates via frequency control, reducing frequent starts/stops and energy consumption.  

**III. Applicability and Maintenance**  
- **Broad Applicability**: Suitable for metallurgy, mining, construction materials, and chemical industries, particularly in coarse crushing stages of sand/aggregate production lines.  
- **Easy Maintenance**: External gearbox vibrator design enables quick assembly replacement, lowering failure rates and maintenance costs.  

**IV. Stability and Reliability**  
- **Stable Vibration**: Scientifically designed rigidity ensures stable operation under full loads or tilted empty conditions, maintaining consistent feeding performance.  
- **Durability**: Critical components use wear-resistant materials to withstand harsh conditions, extending overall equipment lifespan.  

By leveraging these features, linear vibrating feeders significantly enhance production line efficiency and operational reliability.
