Screw Air Compressor

 

Choosing between a screw air compressor and a piston (reciprocating) compressor is a common challenge in drilling projects. The two types operate differently and are suitable for different working conditions.

 

 

 

Compared with traditional piston compressors, screw air compressors offer significant advantages in demanding drilling environments:

While screw air compressors offer significant advantages, it’s important to understand their limitations before making a decision.

 

 

In drilling operations, the air compressor is not just a support machine — it is the core power source of the entire system.In mining applications, a properly selected air compressor for mining drilling must provide both sufficient pressure and airflow to ensure efficient rock breaking and debris removal.

 

Key Functions:

• Powering the DTH hammer to break rock efficiently
• Removing cuttings from the borehole to prevent blockage

 

Basic Workflow:

• The compressor generates high-pressure compressed air
• Air is delivered to the DTH hammer
• The hammer impacts and breaks the rock
• Airflow carries debris out of the hole

 

Why Air Pressure and Airflow Matter

In real drilling conditions, air pressure and airflow are not just technical parameters — they directly affect drilling results.

If the air pressure is too low, the DTH hammer cannot deliver enough impact force, which leads to slower penetration and poor rock breaking, especially in hard formations. On the other hand, if airflow is insufficient, cuttings cannot be discharged efficiently from the hole. This can cause repeated crushing, hole blockage, and increased wear on drilling tools.

A stable combination of sufficient pressure and airflow ensures that the hammer works at full efficiency while keeping the hole clean. This is what maintains consistent drilling speed, reduces tool consumption, and helps achieve better hole quality, especially in deeper or more complex drilling conditions.

Choosing a screw air compressor for drilling is not just about buying equipment—many users face serious issues due to incorrect selection or configuration. Here are the most common problems and how we solve them:

 

❌ Problem 1: Low Drilling Efficiency

Many contractors choose compressors with insufficient pressure or airflow, resulting in slow penetration rates and reduced productivity.

✅ Our Solution:
We recommend the correct pressure (bar) and airflow (m³/min) based on your drilling depth, rock hardness, and DTH hammer size to ensure maximum drilling efficiency.

 

❌ Problem 2: Excessive Fuel Consumption

Oversized compressors often lead to unnecessary fuel costs, especially in long-term projects.

✅ Our Solution:
We help you select the most cost-effective compressor configuration, avoiding oversizing while maintaining performance.

 

❌ Problem 3: Frequent Equipment Failures

Unstable compressors or mismatched systems can cause overheating, wear, and unexpected downtime.

✅ Our Solution:
We provide reliable rotary screw air compressors and ensure proper matching with drilling rigs and tools for stable long-term operation.

 

❌ Problem 4: Poor Performance in Hard Rock

Standard compressors may not deliver enough pressure for granite or basalt formations.

✅ Our Solution:
We recommend high-pressure compressors (18–25 bar) specifically designed for hard rock drilling.

 

❌ Problem 5: Not Sure Which Model to Choose

Many customers are unsure how to select the right compressor for their project.

✅ Our Solution:
We offer one-to-one matching service, helping you choose the best compressor based on:

• Drilling depth
• Rock condition
• Hole diameter
• Budget

 

 

Installing and commissioning a screw air compressor correctly is essential for achieving optimal performance and long-term reliability in drilling operations.

However, many customers face challenges such as improper installation, incorrect parameter settings, and lack of technical guidance—leading to reduced efficiency and potential equipment damage.

 

✅ Our Support Includes:

• Professional installation guidance (remote or on-site)
• Parameter setup based on your drilling conditions
• System matching with drilling rigs and DTH tools
• Troubleshooting support during initial operation

We ensure your equipment runs efficiently from day one.

 

 

The price of a screw air compressor varies depending on pressure, airflow, and configuration.

 

Typical factors affecting price include:

• Airflow capacity (m³/min or CFM)

• Working pressure (bar)

• Diesel vs electric type

• Brand and component quality

 

For example:

• Small portable screw air compressor → Lower cost

• Medium diesel screw air compressor → Moderate price

• High pressure industrial screw air compressor → Higher investment

In drilling projects, choosing the right size is more important than choosing the cheapest option.

Oversized compressors increase fuel cost, while undersized compressors reduce drilling efficiency.

We help you select the most cost-effective screw air compressor solution based on your actual project needs.
