KEMROC mining attachments are engineered to deliver high-performance, productive operations in surface mining, underground scaling, and selective mineral extraction—especially in soft to medium-hard formations such as rock salt, gypsum, bauxite, claystone, phosphate, coal, calcium carbonate, sandstone, and limestone.
These cutter attachments operate with high torque and precision to support controlled excavation without blasting. By delivering low-vibration rock removal, fine-grained output that can help reduce secondary crushing, and energy savings of up to 40%, KEMROC attachments help improve operational safety and reduce total cost per ton mined.
Suitable for excavators ranging from approximately 1,300 lb to 275,000 lb operating weight, KEMROC attachments are widely used in post-blasting scaling, drift development, overburden removal, bench shaping, mine wall scaling, and mineral recovery in open-pit and underground mining environments.
Why Choose KEMROC Mining Attachments?
Designed for Selective Mining of Soft to Medium-Hard Minerals
KEMROC EK Chain Cutters and KR Drum Cutters are purpose-built for mining materials up to approximately 11,600 psi UCS, including gypsum, coal, rock salt, claystone, bauxite, calcium carbonate, sandstone, and phosphate, without the use of explosives. The fine-grained output and precise cutting help minimize material dilution, allowing 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, low-vibration cutting. This helps improve worker safety and reduce structural damage during shaft preparation or drift maintenance.
Energy-Efficient Rock Cutting with up to 40% Less Power
EK attachments can deliver comparable productivity to drum cutters while consuming up to 40% less energy, thanks to their chain-driven central material removal system. This helps reduce 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 for 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 well suited for selective mining. This leads to lower dilution, higher recovery efficiency, and improved material purity, especially 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 tools or manual chipping, KEMROC Drum Cutters offer a low-vibration solution for scaling operations, especially in ceiling zones. They help 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, helping boost daily output.
High-torque hydraulic motors deliver steady cutting performance, even in compact or layered mineral deposits, which is essential for stable productivity in selective mining.
Fine-grained material output allows for easier transport or potential reuse, helping reduce the need for on-site crushing or secondary processing.
Flexible, configurable cutting widths make it easier to adapt tools for narrow drift excavation or broad surface removal, improving on-site versatility.
Low-dust and low-vibration cutting helps maintain air quality and structural stability, making KEMROC attachments well suited for underground mining environments and safety-conscious operations.
Compact attachment designs fit into narrow galleries or tunnels and can be paired with long-reach excavators for improved accessibility.
Wear-optimized pick layouts help extend tool life and reduce maintenance in abrasive formations such as 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, sandstone, 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 used for post-blasting scaling to remove loose material from mine walls, ceilings, and tunnel profiles. This helps improve mine safety and provides clean surfaces for inspection or support installation.
Underground Drift and Tunnel Development
In shaft sinking and drift development, KEMROC Drum Cutters provide precise, low-vibration cutting through layered formations. They are well suited 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 disturbance to surrounding rock. Fine-grained output helps reduce waste and simplify hauling in operations such as phosphate or limestone mining.

FAQs About Mining & Quarrying
-
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 can reduce 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 supports mining in noise- or vibration-restricted zones and helps improve safety when working near live equipment or infrastructure. The fine-grained material output can also support easier hauling and may reduce the need for further processing.
-
Can excavator attachments maintain consistent output in abrasive mineral formations?
Yes. KEMROC Drum Cutters and Chain Cutters are fitted with wear-resistant picks and optimized tool geometry to help maintain cutting performance, even in abrasive soft rock such as silica sand or bauxite. The optimized pick layout can help extend replacement intervals and lower 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, known as dilution, helping improve 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 with more control—especially in weak or layered formations such as claystone or marl.
-
How do excavator attachments handle confined spaces typical of underground drift work?
With sizes starting from tools compatible with approximately 1,300 lb mini excavators and up to long-arm models mounted on approximately 275,000 lb carriers, KEMROC attachments are designed for compact gallery environments. Their low profile, side-shift adapters, and compatibility with tilt rotators give operators greater maneuverability in tight underground spaces.
