In a mountainous region of Vietnam, a small quarry owner was facing mounting pressure from local authorities and nearby residents. His operation extracted granite blocks for construction and memorial stones. For years, he had used traditional blasting methods to break large boulders. But the vibration cracked the walls in a nearby village. Dust covered the surrounding vegetation. And the local government had threatened to revoke his license.
The owner needed a non‑explosive solution. He discovered a rock-splitting machine from YG Machinery – specifically the YG‑350 model with an electric-hydraulic pump and two splitting guns. This hydraulic rock splitter machine uses a 350mm wedge, delivers 800 tons of splitting force, and operates with zero vibration, zero noise, and zero dust.
The change was immediate. The Vietnamese quarry now splits granite boulders cleanly and quietly. The village no longer feels tremors. Dust levels dropped dramatically. The owner increased daily production by 40% because the splitter works in any weather, unlike blasting, which requires dry conditions. He has since ordered a second pump station to run four guns simultaneously.

Technical Parameters Of The Rock Splitter Machine
Below are the specifications for the YG series rock splitters. The Vietnamese customer chose the YG‑350 model.
| Model | YG-250 | YG-350 | YG-450 |
| Wedge Length(mm) | 250mm | 350mm | 450mm |
| Piston Stroke(mm) | 90/220mm | 90/220mm | 90/220mm |
| Drilling Depth(mm) | >500mm | >700mm | >900mm |
| Punching Diameter(mm) | 42mm | 46mm | 46mm |
| Crack Width(mm) | 10-20mm | 10-20mm | 10-20mm |
| Cleavage Time(s) | 10-15/s | 10-15/s | 10-15/s |
| Splitting Force(T) | 500t | 800t | 800t |
| Weight(kg) | 240kg | 250kg | 260kg |
Why the YG‑350 suited the Vietnamese quarry:
- 350mm wedge length matched the granite block sizes that the quarry processed.
- 800 tons of splitting force handled the hard, dense granite typical of the region.
- 10‑15 seconds per split – fast enough to keep production moving.
- 46mm punching diameter aligned with standard rock drill bits available locally.
Three Challenges That Made Blasting Unsustainable In Vietnam
The Vietnamese quarry owner faced three problems common across Southeast Asian mining and construction.
Problem 1: Vibration Damage
Blasting sent shockwaves through the ground. Nearby homes developed cracks. Local authorities received complaints weekly. The quarry risked closure.
Problem 2: Dust and Noise Pollution
Explosives generated thick dust clouds that settled on crops and houses. The noise frightened livestock and disturbed the community.
Problem 3: Weather Dependency
Blasting cannot be done during heavy rain (wet explosives are unstable) or strong winds (dust spreads further). Vietnam‘s monsoon season meant the quarry lost weeks of production.
The rock splitter machine solved all three.
How The Hydraulic Rock Splitter Machine Transformed The Quarry？
The YG rock splitter works on a simple hydraulic principle. A pump station pressurises oil and sends it through hoses to the splitting gun. Inside the gun, a piston pushes a wedge between two counter‑wedges. The wedge expands outward, applying force to the borehole walls. When the pressure exceeds the rock‘s tensile strength, the rock cracks along natural planes.
Zero Vibration
Because the force is static (pushing, not impacting), there is no ground vibration. The Vietnamese quarry owner measured zero tremors at the village boundary. No more complaints. No more threats of closure.
Zero Dust, Zero Noise
The splitter produces no airborne dust – just a clean crack. Noise levels are lower than those of a jackhammer. The crew works without masks (though they still wear them) and neighbours cannot hear the operation.
Works In Any Weather
Rain, wind, or sunshine – the hydraulic rock splitter machine works consistently. The Vietnamese quarry now operates year‑round, catching up on production during the monsoon months when blasting was impossible.
Precise Splitting
The operator controls the splitting direction by drilling holes along the desired crack line. This allows the quarry to produce regular block sizes with minimal waste. Granite blocks are split square and clean.
Real Feedback From The Vietnamese Quarry Owner
After six months of using the YG‑350 rock splitter machine, the owner shared his results.
- Daily production: Increased by 40% because the splitter works in all weather.
- Vibration complaints: Dropped to zero. The village council withdrew their objection.
- Dust control: The splitter produces minimal dust compared to blasting.
- Operating cost: Electricity for the pump station costs a fraction of what explosives used to cost.
- Safety: No flyrock, no misfires, no permit delays.
The owner said, “I was forced to choose between closing the quarry or finding a new method. The rock splitter machine saved my business. It splits granite cleanly, quietly, and safely. My workers like it because they don‘t have to run for cover. I am ordering a second pump station so we can split from both ends of a block.”
An operator added, “The hydraulic rock splitter machine is simple. We drill the hole, insert the gun, start the pump, and wait 10 seconds. Crack. Move to the next hole. We split six blocks per shift easily.”
Ready To Split Rock Safely And Efficiently In Vietnam?
The Vietnamese quarry proved that a hydraulic rock splitter machine is a practical, cost‑effective alternative to blasting: no vibration, no dust, no permits, no weather delays. The YG‑350 delivers 800 tons of splitting force – enough for the hardest granite – and operates on simple hydraulic principles that any worker can learn in one day.
