Large-area quarry blasting requires evenly spaced and consistently drilled holes. The S250 rock drill helps achieve this through steady penetration and controlled operation. Uniform drilling improves blasting results, reduces oversized rock, and lowers secondary breaking costs.
As a professional manufacturer specializing in rock drilling machinery, Shenli Pneumatic Machinery Co., Ltd. independently researches, develops and produces the S250 surface rock drill, a high-performance pneumatic mining tool tailored for large-area quarry blasting. The S250 is easy to operate: connect it to a matching air compressor to provide stable power, adjust the drilling depth and speed according to the rock hardness, and its ergonomic design allows a single operator to complete the drilling operation smoothly without complicated training. Unlike traditional air-leg rock drills, it integrates stability and efficiency, eliminating the need for frequent manual adjustment during operation.
The difference between using the S250 and ordinary air leg rock drill in mines is remarkable. Before adopting the S250, ordinary air-leg rock drills had low drilling efficiency, only 2-3 meters per hour, with uneven hole spacing and easy deviation, leading to uneven blasting, more oversized rocks, and high secondary breaking costs. After switching to the S250, the drilling efficiency is increased by 65% , reaching 5-6 meters per hour. Its precise operation ensures uniform hole spacing and consistent depth, which not only optimizes the blasting effect and reduces oversized rocks by 40% , but also cuts secondary breaking costs by 35% . In addition, ordinary air-leg rock drills are noisy and labor-intensive, while the S250 adopts advanced noise reduction technology, reducing noise by 50% and greatly reducing operator fatigue.
Choosing Shenli Pneumatic Machinery Co., Ltd. means choosing reliability and efficiency. We have 15 years of experience in manufacturing rock drilling machinery, with a complete production line and strict quality control system, ensuring that each S250 meets industry standards. We provide customized solutions according to different quarry needs, as well as 24-hour after-sales service to solve operational problems in a timely manner. The S250 not only improves drilling efficiency and reduces costs, but also has strong durability, with a service life 2 times longer than ordinary rock drills, reducing equipment replacement costs. For quarries pursuing high efficiency and low cost, the S250 is the most cost-effective choice.
Downtime can significantly impact quarry profitability. The S250 is designed for easy maintenance, allowing quick access to key components and reducing service time.
As a result, quarry operators can sustain high daily output while minimizing interruptions to drilling schedules.
Developed by our professional rock drilling machinery factory with over 15 years of industry expertise, the S250 is a hydraulic surface rock drill engineered specifically for demanding quarry and open-pit mining environments. Unlike conventional air-leg rock drills that rely on compressed air, this machine integrates a high-torque hydraulic system to deliver consistent power across various rock formations—from limestone to granite with a uniaxial compressive strength of up to 250 MPa. Its core components, including the carbide-tipped drill bit and shock-absorbing mechanism, are precision-manufactured in our in-house forging and heat treatment workshops, ensuring durability even in 24/7 operation cycles.
