KEMROC’s mining attachments are engineered to deliver exceptional performance & highly productive operations in surface mining, underground scaling, and selective mineral extraction—especially in soft to medium-hard formations like rock salt, gypsum, bauxite, claystone, phosphate, coal, calcium carbonate, sandstone and limestone. These cutter attachments operate with high torque and precision faster than any other tool to ensure controlled excavation without blasting. By delivering vibration-free rock removal, fine-grained product to save further crushing steps, and energy savings up to 40%, KEMROC attachments improve operational safety and reduce total cost per ton mined. Suitable for excavators ranging from 0.6 to 125 tons, KEMROC attachments are widely used in scaling application after blasting, drift development, overburden removal, bench shaping, mine wall scaling, and mineral recovery in open-pit and underground environments.
Why Choose KEMROC Mining Attachments?
Designed for Selective Mining of Soft to Medium-Hard Minerals
KEMROC EK chain cutters & KR Drum Cutters are purpose-built for mining materials up to 80 MPa UCS—including gypsum, coal, rock salt, claystone, bauxite, calcium carbonate, sandstone and phosphate—without the use of explosives to ensure high productivity. The fine-grained output and precision of cut help minimize material dilution, allowing for cleaner separation of valuable minerals from surrounding rock.
Surface and Underground Scaling with High Precision
Rotary drum cutters from the KR and KRD ranges are used for removing loose rock from tunnel walls and mine ceilings with controlled, vibration-free cutting. This ensures worker safety and reduces structural damage during shaft preparation or drift maintenance to make it faster than any other tool.
Energy-Efficient Rock Cutting up to 40% Less Power
EK attachments deliver the same productivity as drum cutters but consume ~40% less energy, thanks to their chain-driven central material removal system. This reduces fuel usage, hydraulic stress, and wear on the excavator swing gear
Reduced Need for Blasting in Mineral Recovery
Where drilling and blasting are restricted, EK chain cutters and KR drum cutters provide a reliable mechanical excavation alternative—ideal for highly productive operations in sensitive, populated, or regulated mining areas.
Optimized Material Recovery
EK chain cutters enable highly targeted excavation with minimal disturbance to adjacent rock layers—making them ideal for selective mining. This leads to lower dilution, higher recovery efficiency, and improved material purity—especially valuable in operations involving phosphate, rock salt, or gypsum where product quality directly affects market value.
Enhanced Operator Safety in Underground Scaling
Unlike traditional methods involving impact or manual chipping, KEMROC’s drum cutters offer a vibration-free solution for scaling operations, especially in ceiling zones. They minimize falling debris risk and reduce equipment recoil—improving working conditions in confined and potentially unstable mine areas.

Optimized Drive Systems and Durable Components enable continuous operation in demanding mining conditions with reduced tool change frequency.
Rotary Cutting Efficiency allows operators to advance faster through mineral seams than with impact tools or manual scaling—boosting daily output.
High Torque Hydraulic Motors deliver steady cutting performance, even in compact or layered mineral deposits—essential for stable productivity in selective mining.
Fine-Grained Material Output allows for immediate transport or reuse, reducing the need for on-site crushing or secondary processing.
Flexible, Unlimited Cutting Widths make it easy to adapt tools for narrow drift excavation or broad surface removal, improving versatility on site.
Low Dust and Low Vibration cutting helps maintain air quality and structural stability—ideal for underground mining environments and safety compliance.
Compact Attachment Designs fit into narrow galleries or tunnels and can be paired with long-reach excavators for improved accessibility.
Wear-Optimized Pick Layouts extend tool life and reduce maintenance in abrasive formations like silica-rich bauxite or claystone.

Mining Applications for KEMROC Attachments


Surface Mining of Soft to Medium-Hard Minerals
KEMROC attachments are used for extracting surface deposits of rock salt, gypsum, bauxite, claystone, phosphate, coal, calcium carbonate, sand stone and limestone. Chain cutters provide narrow, clean trench cuts with reduced over-excavation and lower fuel usage.
Scaling and Surface Preparation
Rotary drum cutters are employed for scaling after blasting for loose material from mine walls, ceilings, and tunnel profiles. This enhances mine safety and ensures clean surfaces for inspection or support installation.
Underground Drift and Tunnel Development
In shaft sinking and drift creation, KEMROC drum cutters provide precise, vibration-free cutting through layered formations. Ideal for expanding existing galleries or shaping tunnel sections for lining.
Selective Mineral Recovery Without Blasting
EK chain cutters and KR Drum Cutters allow precise extraction of mineral seams while minimizing surrounding rock damage. Fine output reduces waste and simplifies transport in operations like phosphate or limestone mining.

FAQ
What makes excavator attachments suitable for mining soft minerals instead of traditional methods?
Mechanical excavation using KEMROC attachments offers better control, cleaner material separation, and eliminates the need for drilling or blasting—especially in open-pit or underground mining of rock salt, gypsum, bauxite, claystone, phosphate, coal, calcium carbonate, sandstone and limestone. It also allows mining in noise- or vibration-restricted zones and improves safety when working near live equipment or infrastructure. Producing Fine-Grained Material Output ideal for direct transport without further processing.
Can excavator attachments maintain consistent output in abrasive mineral formations?
Yes. KEMROC drum and chain cutters are fitted with wear-resistant picks and optimized tool geometry that maintain cutting performance even in abrasive soft rock such as silica sand or bauxite. Regular pick replacement intervals are extended due to the optimized layout, lowering maintenance frequency in high-volume operations.
How do KEMROC attachments improve selectivity in mineral recovery?
The narrow profile of EK chain cutters allows for selective layer removal along seams or zones of interest. This reduces the unintentional removal of surrounding rock (“dilution”), ensuring better grade control—a critical factor in phosphate and salt mining where purity drives commercial value.
What challenges in underground scaling are addressed by drum cutters?
In traditional scaling, operators use impact-based tools that generate rebound force, high noise, and the risk of rockfall. Drum cutters from the KR and KRD ranges offer a rotational, low-impact method that allows miners to remove loose material after blasting from walls and ceilings more safely and with more control—especially in weak or layered formations like claystone or marl.
How do excavator attachments handle confined spaces typical of underground drift work?
With sizes starting from tools compatible with 0.6 t mini excavators, and up to long-arm models mounted on 125 t carriers, KEMROC attachments are designed for compact gallery environments. Their low profile, side-shift adapters, and compatibility with tilt rotators give operators full maneuverability in tight underground spaces.
