# Industrial Specification: Dust Collection Hopper

## 1. Technical Definition
A funnel-shaped container that collects and temporarily stores dust and particulate matter captured by a dust collection system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-2.5 kPa negative pressure differential**. Failure boundary: **3.2 kPa negative pressure differential causing structural collapse**, Mechanism: **Euler buckling failure of conical shell under external pressure exceeding critical buckling pressure P_cr = (2πE/√3(1-ν²))*(t/R)², where E=200 GPa (steel), ν=0.3, t=2 mm wall thickness, R=0.5 m radius**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electrostatic discharge accumulation reaching 25 kV/m field strength | 8 | Dust explosion initiation via minimum ignition energy of 10 mJ for wood dust | Grounding system with resistance &lt;1 Ω and explosion venting panels rated for 0.1 bar overpressure |
| Moisture ingress increasing dust bulk density from 300 kg/m³ to 650 kg/m³ | 8 | Structural overloading exceeding 1.5 kN/m² design load | Humidity sensors with 3% RH accuracy and automated heating elements maintaining &gt;15°C dew point margin |
