A hydraulic concrete splitter breaks rock and concrete without blasting or heavy vibration. It uses hydraulic pressure to push wedges into pre-drilled holes. The wedges expand from inside, creating enough force to crack the material. This method is quiet, dust‑free, and safe for tight spaces.The machine has two main parts: a hydraulic power station and a splitter gun. The power station sends high‑pressure oil to the gun. The gun then drives the wedges forward. The splitting force can reach hundreds of tons. This makes the hydraulic stone splitter a preferred choice for demolition and mining work.
The working pressure reaches 60MPa, above the industry average of 50MPa. A single split completes in about 3 seconds. Daily processing capacity averages 200 m³. The machine accepts drill holes from φ38‑45mm, with compatible depths from 300‑800mm. It carries ISO 9001 and CE certifications.
Precise Control:The splitter directs force exactly where needed. Crack expansion stays within ±5cm accuracy. This protects nearby structures from damage.
Safe Operation:No blasting means no flying stones. No vibration means less risk to workers and adjacent buildings. The machine includes an overload pressure relief valve for extra safety.
Low Noise and Zero Dust:The splitting process generates very little sound. It produces no dust. This makes the rock splitter installed on excavator or handheld use suitable for residential areas, indoor work, and tunnels.
Dual Power Options:The power station works with electric or diesel power. Electric models suit city sites (from 7.5kW). Diesel models (25HP) work in remote mining areas without grid access.
Durable Components:The wedges use Cr12MoV alloy steel. This material lasts over 5,000 splitting cycles. The hydraulic oil temperature stays stable at 45±5°C through an intelligent control system. This extends seal life.
Fast System Response:Oil pressure builds in 1.5 seconds or less. Quick‑release oil pipe joints and a visual oil level window make maintenance simple.
David Lee managed a pipeline project in Sydney, Australia. His team needed to demolish old concrete pipes in a busy city center. The site sat close to homes and shops. Noise and vibration limits were strict. Traditional hammers were too loud and slow.
David’s team used the YG hydraulic concrete splitter. The machine worked quietly at night. It split the concrete from inside the pipes. No vibration reached the surrounding buildings. The project finished on time. David noted the splitter’s reliability even in tough conditions.
Case 2: Granite Quarry in Fujian
A stone quarry in Fujian needed to extract granite blocks. Old methods wasted a lot of material. The yield rate stood at only 35%.The quarry switched to the hydraulic stone splitter (another name for the same tool). Workers drilled holes along natural fault lines. The splitter expanded inside the holes. The granite cracked cleanly along the desired lines. The yield rate rose to 82%. Less waste meant more saleable stone. The quarry owner reported higher profits from the same amount of raw rock.
Building Demolition:The splitter breaks concrete walls, floors, and foundations. It works indoors where hammers are too noisy. It removes reinforced concrete without cutting rebars first.
Mining and Quarrying:Miners use the excavator rock splitter for secondary breaking of large ores. Quarries extract dimension stone with minimal waste. The rock splitter installed on excavator increases mobility on site.
Tunnel Construction:Tunneling projects use the splitter in zones where blasting is banned. The low‑vibration method advances work safely.
Road and Bridge Work:The splitter removes old pavement and bridge decks. It breaks machine foundations and other heavy concrete structures.Emergency Rescue. After landslides or earthquakes, the splitter clears rock debris. It runs for long hours without failure.
A: The power station sends high‑pressure oil to the splitter gun. The gun pushes a wedge into a drilled hole. The wedge expands and cracks the material from inside. Concrete has low tensile strength, so it breaks easily under this force.
Q: What hole size is needed?
A: The machine accepts holes from 38mm to 45mm in diameter. Drilling depth should match the model: over 500mm for YG‑250, over 700mm for YG‑350, and over 900mm for YG‑450.
Q: Is the rock splitter for excavator different from the handheld type?
A: The splitting principle is the same. The excavator‑mounted version attaches to the machine’s boom. This gives more reach and power for large jobs. Handheld units work for smaller tasks.
Q: How long does each split take?
A: Each cleavage cycle takes 10 to 15 seconds. The wedge then retracts, and the operator moves to the next hole.
Q: What maintenance does the stone splitter hydraulic system need?
A: Change the No. 68 anti‑wear hydraulic oil every 500 hours. Check the oil level through the visual window. Replace wedges when they show wear. Never start the machine without securing the wedge.
