# Industrial Specification: Collection Hopper

## 1. Technical Definition
A funnel-shaped container that collects recovered powder from the Powder Recovery Unit for temporary storage and controlled discharge.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150 kg powder capacity, 0-0.5 bar internal pressure, -20°C to 80°C temperature**. Failure boundary: **Material yield strength of 235 MPa (S235JR steel) exceeded, wall thickness reduction below 2.5 mm, powder accumulation exceeding 180 kg**, Mechanism: **Hopper wall fatigue failure due to cyclic powder impact loading at 0.5-2.0 Hz frequency, exceeding material endurance limit of 150 MPa**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Powder bridging due to moisture content exceeding 3% by weight | 8 | Flow obstruction causing asymmetric loading and hopper wall deformation | Installation of pneumatic vibrators with 50 Hz frequency and 100 N force rating at 45° hopper wall angle |
| Electrostatic charge accumulation exceeding 5 kV/m in powder stream | 8 | Powder adhesion to hopper walls reducing effective capacity by 40% | Grounding system with resistance &lt;1 Ω and ionization bars at discharge point |

## 3. Key Technical Parameters

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

### Q: What materials are available for the Collection Hopper?
**A**: The Collection Hopper is available in Stainless Steel for corrosion resistance, Carbon Steel for durability, and Food-Grade Plastic for sanitary applications in food or pharmaceutical industries.

### Q: How does the discharge valve work in the Collection Hopper?
**A**: The discharge valve allows controlled release of collected powder from the hopper, preventing spillage and enabling precise material transfer to downstream processes or packaging systems.

### Q: What is the purpose of the level sensor in the Collection Hopper?
**A**: The level sensor monitors powder volume in the hopper, preventing overfilling, optimizing discharge cycles, and enabling automated operation when integrated with powder recovery systems.
