# Industrial Specification: Rotating Grate/Discharge Table

## 1. Technical Definition
A rotating mechanical component within discharge systems that facilitates controlled material transfer and distribution.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 rpm rotational speed, 15-75 kN·m torque capacity, -20°C to 150°C ambient temperature**. Failure boundary: **Exceeds 4.2 rpm causing centrifugal force &gt; 1.8× design limit, torque &gt; 85 kN·m yielding gear teeth at 450 MPa stress, temperature &gt; 180°C reducing steel yield strength by 40%**, Mechanism: **Fatigue failure from cyclic bending stress exceeding 250 MPa at gear root fillets, bearing seizure from lubricant thermal breakdown at 160°C, structural resonance at 3.8-4.1 rpm exciting 12 Hz natural frequency**.

### 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.
