# Industrial Specification: Dust Hopper

## 1. Technical Definition
A conical or pyramidal container that collects and temporarily stores dust and particulate matter separated from air streams by dust collection systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-2.5 bar differential pressure, 0-150°C material temperature**. Failure boundary: **3.0 bar differential pressure causing structural deformation, 200°C material temperature causing thermal degradation**, Mechanism: **Von Mises yield criterion exceeding 250 MPa yield strength of carbon steel, Arrhenius equation thermal degradation at activation energy 80 kJ/mol**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electrostatic discharge accumulation exceeding 10 kV potential | 8 | Dust explosion propagation through hopper volume | Grounding system with resistance &lt;10 ohms and explosion venting at 0.5 bar relief pressure |
| Moisture ingress raising humidity above 60% RH | 8 | Bridging and compaction forming 1.5 g/cm³ dust cakes | Heated jacket maintaining 5°C above dew point and 45° inclined walls |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are available for dust hoppers in machinery manufacturing?
**A**: Dust hoppers are typically constructed from carbon steel, stainless steel, or aluminum, chosen based on corrosion resistance, material compatibility, and budget requirements.

### Q: How does the vibration mechanism work in a dust hopper?
**A**: The vibration mechanism prevents material bridging and ensures consistent dust flow through the discharge outlet by applying controlled vibrations to the hopper walls.

### Q: What are the key components of a dust hopper system?
**A**: Essential components include the hopper body, discharge outlet, support structure, access door for maintenance, and vibration mechanism for material flow management.

## 6. Manufacturing Compliance
- ISO 8573-1:2010 (COMPRESSED AIR PURITY CLASSES)
