Custom Fully automatic rock drillability tester Manufacturer, Pricelist

The fully automatic rock drillability tester is an intelligent experimental device used to evaluate the difficulty level (drillability) of rock drilling. By simulating the drilling process and quantifying the rock's resistance to drilling, it provides key parameters for fields such as petroleum drilling, geological exploration, and mining.

Functions

-Automated determination of rock drillability index (such as micro drilling rate index (MDR) drillability level value (DR), etc.).
-Simulate real drilling conditions (rotational speed, drilling pressure, drill bit type, etc.) and predict actual drilling efficiency.

Frequently Asked Questions

Q1 What are the major components of the drilling system?

The system consists of an electric control drill bit (standard size hard alloy/diamond drill bit) and a high-precision servo motor that regulates speed and drilling pressure ranging from 0 to 1000 rpm and 0 to 10 kN.

Q2 How does the micro drilling system measure rock drillability?

It evaluates rock properties using two primary principles: the Micro Drilling Speed Method, which measures drilling depth (mm/min) under standard parameters, and the Energy Method, which assesses energy consumption via torque and speed parameters.

Q3 Which industry standards does this testing system comply with?

The equipment is fully compliant with standard guidelines including API RP 10B (petroleum industry testing specification for drilling fluids) and ISO 22476-12 (geotechnical engineering investigation standards).

Q4 What rock sample dimensions are compatible with the fixture?

The standard rock sample sizes supported are side lengths of 100 × 100mm and Φ25 × 80mm. Custom sample specifications are also available upon selection to accommodate different testing needs.

Q5 What sensors are integrated for real-time data collection?

The system integrates a displacement sensor with 0.01 mm precision for depth tracking, a torque sensor for real-time resistance monitoring, and an optional vibration/acoustic emission sensor to study fragmentation features.
