# Industrial Specification: Hopper and Agitator

## 1. Technical Definition
A combined component consisting of a hopper for material storage and an agitator for mixing or preventing material settling

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 m³ capacity, 0.1-2.0 bar internal pressure, 5-60 RPM agitator speed**. Failure boundary: **Agitator torque exceeding 450 Nm at 60 RPM, hopper wall stress surpassing 150 MPa yield strength, material bridging at particle size &gt;5 mm with moisture content &gt;8%**, Mechanism: **Fatigue failure from cyclic loading at agitator shaft stress concentrations (σ_max &gt; 0.7σ_yield), abrasive wear at particle-wall interface exceeding 0.5 mm/year erosion rate, material arching due to Janssen effect with wall friction coefficient μ &gt; 0.6**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Bearing lubrication degradation below ISO VG 32 viscosity at 40°C | 8 | Agitator shaft seizure at &gt;100°C bearing temperature | Forced lubrication system with 0.1 MPa minimum pressure and PTFE-coated bearings |
| Material phase change from free-flowing to cohesive state at moisture content &gt;6% | 8 | Hopper bridging with zero discharge flow | Internal hopper wall coating with fluoropolymer (coefficient of friction &lt;0.2) and 200 W/m² heating elements |
