# Industrial Specification: Vibrating Feeder

## 1. Technical Definition
A mechanical device that uses vibration to move bulk materials from storage hoppers or bins to downstream processing equipment at a controlled rate.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-5.0 m/s² vibration amplitude, 15-60 Hz frequency, 0-100°C ambient temperature**. Failure boundary: **Vibration amplitude exceeding 6.0 m/s² causes structural resonance, spring fatigue at 10⁷ cycles (S-N curve for 65Mn steel), bearing temperature &gt;120°C**, Mechanism: **High-cycle fatigue failure in spring elements due to stress concentration at grain boundaries (Paris' Law: da/dN = C(ΔK)^m where C=6.9×10⁻¹², m=3.0), bearing seizure from lubricant breakdown at 120°C (Arrhenius equation: k=Ae^(-Ea/RT) with Ea=80 kJ/mol)**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.

- **Caution**: 

### Q: What materials are your vibrating feeders compatible with?
**A**: Our vibrating feeders are designed to handle various bulk materials including aggregates, grains, minerals, and industrial powders, with troughs made from carbon steel or abrasion-resistant steel for durability.

### Q: How does the vibration mechanism work in these feeders?
**A**: The feeder uses an exciter/vibrator unit to generate controlled vibrations that move materials along the trough. The spring system isolates vibrations from the base frame while maintaining consistent material flow.

### Q: What maintenance is required for vibrating feeders?
**A**: Regular inspection of the spring system, trough wear plates, and vibrator components is recommended. Our abrasion-resistant steel construction minimizes wear, but periodic checks ensure optimal performance and longevity.
