Quiet explosion without shock, precise drilling
Traditional rock mining has long been stuck in "blasting dependence": the shock endangers surrounding buildings, dust and noise are complained by residents, and the approval is limited and the construction period is delayed. The low efficiency of the breaker makes the project worse. The construction party is forced to struggle in the triangular dilemma of "safety, efficiency, and cost" - both to meet strict environmental regulations and to ensure the progress of mining. Although Drilling Rigs can drill holes, they cannot replace blasting, and manual splitting is even more difficult to apply on a large scale.
The advent of Juqiang and Farun airborne splitters has ended this tug-of-war! It innovatively combines Excavator Converted Drilling Rigs with hydraulic splitting technology: after pre-drilling the hole, insert the wedge-shaped splitting head, drive the center wedge block with 60-100Mpa high pressure, convert the axial hydraulic pressure into 3800-5000 tons of lateral splitting force, directly hit the natural weakness of the rock where the tensile strength is far lower than the compressive strength (only about 10%), and achieve precise splitting 158. This solution does not require blasting permits and can be directly mounted on the hydraulic system of excavators above 12 tons, turning the equipment into intelligent Drilling And Splitting Machines in seconds.
The actual effect is convincing: a single operation takes 40-50 seconds, and the efficiency is as high as 60-80㎡/hour with a breaker under bluestone conditions; the life of the wedge iron exceeds 30,000 times, and the hydraulic system operates stably for 10 years89. On-site verification shows that the splitting direction error is controllable, there is no flying stone dust, and it is still safe to operate within 10 meters of the precision equipment - truly realizing "mining without disturbing the people, and demolition without vibration"45.
Three core features create competitiveness
① Thousand-ton static explosive force: 105-110mm wedge diameter with 1700mm effective length, burst 5000 tons of splitting force, hard rock disintegrated at one time8;
② Excavator switching in seconds: adapted to 12-30 ton excavator hydraulic interface, hydraulic control automatic hole alignment, no need for professional technicians17;
③ Zero pollution: working noise ≤65dB, no dust and vibration, in line with urban construction environmental protection standards49.
Two tips for efficiency improvement
1. Hole network optimization: granite splitting surface is flattest when hole spacing is 2.5-3m and row spacing is 1.5-1.8m8;
2. Drilling and splitting in one: with Beretta WL215 SP and other drilling rigs (drilling depth 61m + torque 185Nm), drilling and splitting are seamlessly connected610.
Use static to control hardness, break rocks with ingenuity - let safety and efficiency no longer be in opposition.
