Rock Breaking Machine

When you manage a construction or mining project, you need a reliable rock breaking machine to keep your work on schedule. This industrial equipment turns large hard stones, concrete structures, and frozen ground into small pieces. However, you must look at specific technical data like chisel diameter, operating pressure, and oil flow before buying.

To select the best equipment, you must check your carrier size and your daily production goals. Buying a hammer that does not match your excavator can damage your carrier hydraulic pump or cause high maintenance costs.

Match The Hydraulic Breaker Machine With Your Excavator Weight

You cannot just install any hydraulic breaker machine onto your excavator or backhoe loader. The operating weight of your excavator determines the size of the breaker you can use safely. We design our hammers to cover an extremely wide range from 0.5 ton micro diggers up to 80 ton heavy mining excavators.

• Micro & Mini Excavators (0.5 to 4.5 Tons): Models like YG350, YG400, YG450, and YG530 are ideal. They feature a chisel diameter from 35mm to 53mm and weigh less than 100 kg, perfect for light residential work.
• Medium Carriers (4 to 15 Tons): Models like YG680, YG750, and YG850 provide a strong balance. They operate at 110 to 160 Kg/cm² pressure, delivering fast impacts for utility trenches.
• Heavy Duty Excavators (15 to 80 Tons): For massive quarrying, models from YG1250 (125mm chisel) up to our largest YG2100 (210mm chisel, 3396 kg body weight) deliver maximum striking energy.

Our production team ensures that every oil port, mounting pin, and hydraulic hose connects perfectly with major international excavator brands.

When To Use A Mini Rock Breaker In Tight Spaces

Large projects are not the only places where you need to break stones. In many urban environments, a mini rock breaker is the best choice because large machines cannot enter the workspace. These small but powerful attachments offer high mobility and high speed.

• Indoor Demolition: Models like YG350 and YG400 feature a high blow frequency of 800 to 1300 bpm. This makes them excellent for breaking thin concrete floors or walls inside older factory buildings quickly.
• Trenching Work: Opening narrow paths for city water pipes and internet cables with a 1/2 inch hose diameter that fits mini loaders easily.
• Road Repair: Removing damaged asphalt and concrete layers on narrow streets without blocking all traffic, using an oil flow of just 15 to 25 l/min.

The compact design allows your small skid steer loader or mini digger to become a high-efficiency demolition tool within minutes.

Select The Correct Chisel Types For Varied Work Conditions 

Using the right chisel on your rock breaking machine determines whether you finish your task early or break your tool on day one. Different geological conditions require specific tip shapes to maximize the impact energy from the piston. Matching the chisel to the hardness of the rock ensures high efficiency and prevents blank firing damage to your hydraulic breaker machine. 

• Moil Chisels for Concrete and Soft Rock: The pointed tip concentrates all striking energy into a single spot. It is the best choice for demolition jobs, brick walls, and soft layered stone where you need deep penetration. 
• Wedge Chisels for Trenching and Bedrock: Also known as a flat chisel, this tool works like a knife. It is ideal for cutting straight trenches, excavating soft to medium limestone, and separating layered sandstone. 
• Blunt Tools for Secondary Rock Breaking: This tool features a flat, wide surface. Instead of penetrating the stone, it delivers a massive shockwave to shatter large, hard boulders in quarries that have already been blasted. 
• Cone Point Tools for Hard Granite: The conical shape provides excellent wear resistance when dealing with highly abrasive materials like quartz and granite, extending the service life of your mini rock breaker. 

When you order a machine for breaking rocks from our factory, our engineers help you choose the exact chisel combination based on your local soil and rock reports. For example, high-frequency models like the YG350 (800–1300 bpm) pair perfectly with small moil points for fast city demolition. Meanwhile, heavy mining models like the YG1850 or YG2100 utilize large 185mm to 210mm blunt tools to crush heavy river stones without losing striking force.

Installation And Daily Maintenance For Long Service Life 

Correct installation and regular service prevent unexpected stops during busy work weeks. When your rock breaking machine arrives at your port, our technical documents guide you through every step. 

• Greasing Every Two Hours: Lubricate the chisel bushing frequently to prevent metal friction and overheating. 
• Check Nitrogen Pressure: Keep the gas pressure within the standard range to maintain consistent striking power based on your model’s operating pressure. 
• Inspect Hydraulic Hoses: Look for any oil leaks or cracks before you start the machine every morning. 
• Correct Working Angle: Always keep the tool perpendicular (90 degrees) to the rock surface to prevent chisel breakage. 

Our team packs each item in seaworthy plywood boxes with moisture-proof plastic wrap. This ensures the equipment stays rust-free during long sea transport.
