# Industrial Specification: Agitator Paddles

## 1. Technical Definition
Mechanical components within a pharmaceutical tablet press feed frame that stir and homogenize powder blends before compression.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 NÂ·m torque at 15-60 RPM**. Failure boundary: **3.2 NÂ·m torque at 75 RPM causing shaft deflection &gt;0.15 mm**, Mechanism: **Bending fatigue failure due to cyclic stress exceeding 275 MPa yield strength of 316L stainless steel under powder resistance forces**.

### 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.

- **Caution**: 

### Q: What materials are recommended for pharmaceutical-grade agitator paddles?
**A**: For pharmaceutical applications, we recommend 316L stainless steel for corrosion resistance and cleanability, or food-grade plastics like PTFE and UHMW-PE for chemical inertness and low friction.

### Q: How do agitator paddles improve tablet press performance?
**A**: Agitator paddles homogenize powder blends in the feed frame, ensuring consistent density and flow. This reduces tablet weight variation, improves compression uniformity, and minimizes production defects.

### Q: What maintenance is required for agitator paddles in continuous operation?
**A**: Regular inspection for wear, cleaning to prevent cross-contamination, and checking fastener tightness. Material choice affects maintenance frequencyâ€”stainless steel offers durability, while plastics may need replacement more often in abrasive blends.

## 6. Manufacturing Compliance
