# Industrial Specification: Impact Crusher

## 1. Technical Definition
A crushing machine that uses impact force to reduce the size of materials by striking them with hammers or blow bars mounted on a rotating rotor.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 MPa hydraulic pressure, 800-1800 RPM rotor speed, 50-300 mm feed size**. Failure boundary: **Rotor imbalance exceeding 0.2 mm/kg at 1800 RPM, hammer tip velocity exceeding 85 m/s, bearing temperature exceeding 120°C**, Mechanism: **Fatigue fracture from cyclic Hertzian contact stress exceeding 1500 MPa at hammer-tip/material interface, thermal expansion mismatch between martensitic steel hammers (α=11×10⁻⁶/°C) and chromium carbide liners (α=6.5×10⁻⁶/°C)**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.

| Symbol | Variable Definition | Localized Reference |

| m | Eccentric Mass | Engineering Constant |
| r | Radius | Engineering Constant |
| \omega | Angular Frequency | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Material work hardening exceeding 450 HB at hammer tips | 8 | Brittle fracture propagation from microcracks at carbide-matrix interfaces | Austempering heat treatment to achieve 40-45 HRC with 15-20% retained austenite for stress accommodation |
| Resonant vibration at 1.8×operating frequency due to uneven wear pattern | 8 | Bearing raceway spalling from dynamic loading exceeding C₀ static load rating by 300% | Asymmetric hammer arrangement with 7° phase offset to disrupt standing wave formation |

- **Caution**: 
- **Caution**: 

### Q: What materials are best suited for processing with this impact crusher in non-metallic mineral manufacturing?
**A**: This impact crusher is ideal for processing non-metallic minerals like limestone, gypsum, dolomite, and aggregates, utilizing high-chromium steel and manganese steel components for durability against abrasive materials.

### Q: How does the hydraulic opening system benefit maintenance and operation?
**A**: The hydraulic opening system allows quick and safe access to the crushing chamber for replacing impact hammers or blow bars and clearing blockages, reducing downtime and enhancing operational efficiency.

### Q: What factors determine the capacity (t/h) and maximum feed size (mm) of this impact crusher?
**A**: Capacity and maximum feed size depend on the rotor diameter, rotor speed, motor power, and material hardness. Custom configurations can be adjusted based on specific production needs in non-metallic mineral processing.
