# Industrial Specification: Feed Hopper

## 1. Technical Definition
A container that temporarily stores and regulates the flow of bulk materials into a processing system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 m³ capacity, 0.1-0.8 bar internal pressure, 15-60°C material temperature**. Failure boundary: **Material bridging at 45° angle of repose, structural failure at 3.0 bar internal pressure, wall abrasion exceeding 6 mm thickness loss**, Mechanism: **Janssen effect causing arching at critical stress ratio σ_h/σ_v = 0.4, fatigue cracking at stress concentration factor K_t = 3.2, abrasive wear following Archard's equation with wear coefficient K = 1.2×10⁻⁶**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Moisture content exceeding 12% in hygroscopic materials | 8 | Material bridging and flow stoppage | Internal vibrators with 50 Hz frequency and 2.0 mm amplitude, conical hopper design with 70° wall angle |
| Cyclic loading at 0.5-2.0 Hz from upstream equipment vibration | 8 | Fatigue cracking at weld joints | Finite element analysis-optimized reinforcement at stress concentrations, post-weld heat treatment at 650°C for 2 hours |

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

### Q: What materials are available for your feed hoppers?
**A**: Our feed hoppers are available in three material options: stainless steel for corrosion resistance and hygiene, carbon steel for durability and cost-effectiveness, and food-grade plastic for applications requiring non-reactive surfaces in food processing.

### Q: What components are included in the feed hopper BOM?
**A**: Each feed hopper includes a hopper body, discharge outlet, gate or valve for flow regulation, and a level sensor to monitor material volume and prevent overfilling or empty running of downstream equipment.

### Q: How does a feed hopper regulate material flow in processing systems?
**A**: The feed hopper temporarily stores bulk materials and uses an integrated gate or valve at the discharge outlet to control the flow rate into your processing system, ensuring consistent material supply and preventing system overload or starvation.
