Double Tube Core Drilling Tool for Mining Exploration - ISO9001 Certified High Efficiency Drilling Rig Equipment
| Product Name | Double Tube Core Drilling Tool |
|---|---|
| Application | Mining Exploration |
| Certification | ISO9001 |
| Key Feature | High Durability |
This single-acting double pipe drilling tool features an innovative design where the outer pipe rotates while the inner pipe remains stationary during operation. This configuration eliminates friction vibration generated by drill rotation, preventing mechanical vibration of the rock core and delivering superior core quality for geological analysis.
The upper joint incorporates a movable environmental protection path with precisely arranged grooves to ensure proper alloy piece diameter. Critical adjustments include:
- Spring seat to internal drill bit step distance controlled via screw and lock nut
- Precisely managed length difference between inner and outer tubes
- Single-action mechanism utilizing spherical, single-bearing, or double-bearing structures
During operation, drilling machine rotational power transfers to the tool while the outer tube connects to the cutting edge. The stationary inner tube (core tube) preserves extracted core in its original geological state by avoiding disturbance.
Five-component system featuring excellent guiding, water-proofing, and card center capabilities. Compatible with specialized carbide or steel drill bits for various salt mine geological layers.
Specialized core drilling solution for talc mine exploration. Features unique flushing liquid flow control through strategic steel ball placement within the system.
Ideal for intact, jointed, or fibrous rock ore formations including asbestos. Available in piston type and ball clamp variations utilizing steel ball placement and pump pressure for secure rock core capture.
Specifically engineered for challenging geological conditions including thin coal seams with alternating soft/hard layers, frequent instability zones, and materials below grade 6 hardness.
The stationary inner tube design ensures minimal core disturbance, providing geologists with high-quality, undisturbed samples for accurate mineral analysis and resource assessment.
