# Industrial Specification: Cold Feed System

## 1. Technical Definition
A system that stores, measures, and proportionally feeds cold aggregates into the asphalt mixing plant.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 MPa (1-20 bar) at 15-40°C ambient temperature**. Failure boundary: **Aggregate moisture content exceeding 5% by mass or feed rate deviation beyond ±2% of setpoint for 30 seconds**, Mechanism: **Hydrodynamic lubrication breakdown in conveyor bearings at feed rates below 20% capacity, causing boundary lubrication regime with coefficient of friction &gt;0.15**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

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

### Q: What materials are used in constructing this cold feed system?
**A**: Our cold feed systems are constructed using high-quality carbon steel for structural components and abrasion-resistant steel plates for areas subject to wear from aggregate movement, ensuring long-term durability and reduced maintenance.

### Q: How does the cold feed system ensure accurate proportional feeding?
**A**: The system utilizes precision control gates and calibrated feeders that work in conjunction with the collection conveyor to measure and maintain consistent aggregate proportions as required by the asphalt mix design specifications.

### Q: What are the main components included in the cold feed system?
**A**: The complete system includes a collection conveyor for aggregate transport, control gates for flow regulation, feed bins/hoppers for storage, and feeders for precise material delivery to the asphalt mixing plant.
