Epiroc MD20: Performance and Usage Tips – Expert Guide

The Epiroc MD20 is a high-performance hydraulic rock drill used in mining and construction applications

It stands out for its durability and precise controls, ensuring reliability and efficiency in the field

This guide provides practical tips to maximize MD20 performance, extend lifespan, and reduce maintenance costs

What is the MD20?

A hydraulic rock drill component operating with high-pressure hydraulic systems

Used in construction, mining, and quarry operations for rock breaking, drilling, and blasting

Its sturdy design and high torque ensure optimal drilling performance

5 Practical Tips to Improve Performance

1. Correct Hydraulic Pressure and Flow Settings

Proper pressure and flow directly affect performance

Low pressure → drill cannot operate at full power

High pressure → components wear out faster

Always follow the manufacturer’s recommended hydraulic settings

2. Use Original Spare Parts

Using original pistons, seal kits, and valve kits ensures longer lifespan

Non-original parts may cause performance drop, hydraulic leaks, and frequent breakdowns

3. Regular Lubrication and Maintenance

Regular lubrication according to operating hours extends component life

Keep hydraulic oil clean

Follow grease intervals

Check bearings regularly

4. Pay Attention to Drilling Angle

The angle relative to the rock and ground determines efficiency and wear

Correct angle → maximum drilling speed

Incorrect angle → excessive load on piston and drill bits

5. Frequent Leak and Fault Checks

Leaks are a major cause of performance loss

Checklist: hose connections, seal and o-ring condition, pipe surfaces

Early detection prevents major failures

Tips to Increase Efficiency with MD20

Proper maintenance → uninterrupted operation

Compatible parts → lower spare part costs

Regular inspections → longer equipment lifespan

Operator training → reduces risk

Common Mistakes

Using cheap, non-original spare parts

Irregular hydraulic oil changes

Fixing the drilling angle in one position

Neglecting operator training 

Conclusion

The Epiroc MD20 delivers high performance and long service life when maintained and used correctly

Small optimizations in the field can increase efficiency and reduce maintenance costs significantly
