# Industrial Specification: Mixing Unit

## 1. Technical Definition
The core component of an asphalt mixing plant where aggregates, filler, and bitumen are thoroughly blended to produce homogeneous asphalt mixture.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 MPa (5-20 bar) internal pressure, 150-180°C operating temperature**. Failure boundary: **Material yield strength of 250 MPa for steel components, 2.5 MPa internal pressure causing permanent deformation, 200°C temperature causing bitumen degradation**, Mechanism: **Von Mises stress exceeding yield strength due to pressure cycling, thermal fatigue from 50°C temperature differentials during heating/cooling cycles, abrasive wear from aggregate particles at 2.5 m/s relative velocity**.

### 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.
