Nord Drivesystems manufactures industrial gear units, motors and control systems specifically engineered for mining applications where equipment operates in extreme conditions with heavy materials and continuous loads.
The company's MAXXDRIVE industrial gear unit series delivers output torques up to 2,495,900 pound-inches for mining equipment including crushers, mills and material handling conveyors. NORD combines these units with energy-efficient motors and variable frequency drives to create integrated systems for mining operations.
MAXXDRIVE series serves large-scale mining equipment
MAXXDRIVE industrial gear units power large-scale conveyor systems, bucket elevators, winches and crushers that handle the high starting loads and continuous operation required for transporting heavy raw materials in mining operations. The series features a one-piece UNICASE housing designed to withstand temperature fluctuations and abrasive dust common in mining environments.
The gear units accommodate cooling systems such as axial fans or internal cooling coils to maintain thermal stability during high-load processing operations. Mining-specific options include elastic input couplings, disc and drum brakes, axial fans, swing bases, auxiliary drives, oil coolers and heaters, and splash lubrication systems.
Two-stage MAXXDRIVE XT units use enhanced thermal designs that the company states often eliminate the need for external cooling in harsh mining environments. The symmetrical design allows mirror-image installation to reduce replacement part inventory for mining operations.
Specialized gear motors for mining applications
UNICASE helical bevel gear units serve mining applications including screw classifiers, travel drives for tripper cars, and conveyors for surface miners, feeder breakers, and mobile or semi-mobile crushing plants for in-pit crushing and screening operations. Eleven case sizes provide torque ranges up to 442,500 pound-inches.
UNICASE parallel shaft gear units power mining excavators, drills and crushers with heavy-duty bearings designed for continuous operation under the heavy stress conditions typical in mining environments.
Motors designed for mining hazards
NORD manufactures dust explosion protected motors and gas explosion protected motors specifically for the hazardous environmental conditions common in mining operations. These motors deliver power from 0.16 to 30.0 horsepower for applications where dust and gas explosion risks are paramount concerns.
The motors meet global efficiency regulations with available configurations including brakes, IP66 protection, encoders, external cooling fans and thermal protection suited for mining environments.
Control systems for mining
NORDAC PRO variable frequency drives provide control solutions for mining applications through six frame sizes up to 200.0 horsepower. An integrated programmable logic controller detects blockages in mining systems and automatically adjusts operation direction to free material blockages, reducing downtime in mining operations.
Functional safety options such as STO and SS1 protect drive systems, materials and operators in mining environments where safety is critical.
Nord Drivesystems continues developing drive systems optimized for mining industry requirements through investment in specialized development and manufacturing technology.
