# Industrial Specification: Paddle Wheel

## 1. Technical Definition
A rotating component with blades or paddles used to move, mix, or convey powdered materials within a feeding system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 m/s peripheral velocity, 0.1-2.0 bar pressure differential**. Failure boundary: **Material fatigue failure at 10^7 cycles for steel alloys (S-N curve), blade tip deflection exceeding 0.5% of diameter**, Mechanism: **High-cycle fatigue from cyclic bending stresses during powder impact, abrasive wear exceeding material hardness (Mohs scale 4-6 powders)**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| C | Dynamic Load Rating | Engineering Constant |
| P | Equivalent Dynamic Load | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Powder bridging causing asymmetric loading | 8 | Shaft bending exceeding yield strength (250 MPa for 4140 steel) | Install torque-limiting couplings with 150% rated torque capacity |
| Abrasive particle size &gt;100 microns at &gt;5% concentration | 8 | Blade erosion reducing thickness below 2 mm minimum | Apply tungsten carbide coating (HV 1400) on leading edges |

- **Caution**: 

### Q: What materials are available for paddle wheels in food processing applications?
**A**: For food processing, we offer food-grade plastic paddle wheels that meet safety standards, as well as stainless steel options that are corrosion-resistant and easy to clean.

### Q: How do I select the right paddle wheel for my powder conveying system?
**A**: Consider material compatibility (stainless steel for corrosive environments, carbon steel for general use, plastic for food-grade), blade design for your powder type, and mounting specifications to match your equipment.

### Q: Can I get replacement blades or hubs for existing paddle wheels?
**A**: Yes, we provide individual BOM components including replacement blades/paddles, hubs, and mounting hardware for most industrial paddle wheel models to minimize downtime.

## 6. Manufacturing Compliance
- ISO 28580:2018 (TIRE ROLLING RESISTANCE MEASUREMENT METHODS)
