AD650 Reverse Circulation (RC) Hammer
1. Basic Concept
- The AD650 is a high-performance pneumatic reverse circulation (RC) hammer in the AD600 series.
- It delivers efficient rock breaking and high-quality sample recovery via reverse airflow, designed for medium-depth mineral exploration and grade control.
- Built with Australian engineering expertise, it is field-proven in diverse harsh global drilling environments.
2. Key Features
- Optimized airflow design: Maximizes air flow for superior flushing efficiency across variable pressures.
- Top-loading inner tube: Enables quick replacement of worn parts, cutting maintenance time.
- Robust build: OD 125 mm, weight 60 kg, with piston case wear protection for long service life.
- Wide bit compatibility: Supports bit sizes from 5-1/4 in (133 mm) to 5-3/4 in (146 mm).
- Versatile pressure range: Operates reliably from low to high air pressures in soft to hard rock.
3. Application Scenarios
- Mining grade control: In-pit grade monitoring before production drilling.
- Mineral exploration: Medium-depth RC drilling for resource definition and sampling.
- Quarry & civil works: Rock excavation, foundation investigation, and road/rail projects.
- Geotechnical drilling: Core sampling in medium-hard to hard rock formations.
4. Main Advantages
- High drilling efficiency: Strong percussion power and excellent flushing deliver fast penetration and clean samples.
- Low maintenance: Minimal internal parts and top-loading design reduce downtime and repair costs.
- Proven reliability: Durable construction ensures stable performance in tough conditions.
- Cost-effective: Balanced performance and durability lower overall drilling costs.
