NORD's reliable solutions for bulk goods accommodate a wide range of plant arrangements and offer various application-specific options for long service life, low maintenance, and excellent load capacity.
NORD Powers Bulk Material Handling with Reliable, Robust Drive Solutions
Case Study from | NORD DRIVESYSTEMS
In the bulk material handling industry, temperature fluctuations, abrasive environments, and rough operating conditions are commonplace. NORD modular drive systems consisting of gear units, electric motors, and intelligent variable frequency drives are individually configured to specific application requirements, accommodating a wide range of plant arrangements and implementation of customer-specific design specifications.
Robust Drive Solutions for High-Performance Stockyard Systems
Stockyard systems are at the heart of bulk material handling operations, providing essential buffering, storage, and blending functions for mining, power generation, cement production, grain, and other industries. NORD provides durable, dynamic drive solutions designed specially for the quantity of material, properties of the material, as well as the ambient operating conditions, ensuring the drive system is matched to the application for continuous operation and maximum throughput. These solutions include robust UNICASE™ helical bevel gear units, heavy-duty MAXXDRIVE XC right-angle and parallel shaft industrial gear units, and UNICASE parallel shaft gear units paired with NORDAC FLEX decentralized variable frequency drives or NORDAC PRO SK 500P control cabinet variable frequency drives. Optimally matched components such as couplings and brakes, plus flexible implementation of customer-specific design specifications including drive pinions, output flanges, and motor swing bases deliver efficient, long-lasting performance.
Reliable Transportation Through Bulk Goods Conveying
In the demanding world of bulk material handling, conveyor systems play a fundamental part in transporting aggregates, grains, powders, and other bulk solids from one part of the facility to another. These systems require drive solutions that are robust, reliable, and efficient to keep operations flowing without downtime or delays. NORD’s solutions are engineered for all types of conveyor applications including horizontal, vertical, inclining, declining, and more. They determine the ideal solution by considering the mass flow rate, conveyor length, and construction to provide a solution that meets precise requirements. Large conveyor systems typically utilize MAXXDRIVE industrial gear units as they offer output torques up to 2,495,900 lb-in, are highly versatile with extensive input and output options, and ensure excellent load capacity for reliable transportation. For smaller conveyor applications such as drag conveyors and screw conveyors, UNICASE helical bevel gear units and UNICASE parallel shaft gear units offer powerful, compact solutions with long service life and low maintenance.
Intelligent Control of Weighing and Metering Systems
Accuracy and efficiency are important when it comes to weighing and dosing systems. NORD drives can be controlled individually via variable frequency drives to intelligently meter, weigh, and adjust mass flow for precise bulk goods infeed control. NORDAC FLEX variable frequency drives and NORDAC PRO SK 500P variable frequency drives feature a POSICON integrated positioning mode and synchronization for high precision control. Plug-and-play capabilities combined with bus system connectors greatly simplify installation and maintenance as signal interference and bulky cables are eliminated. An integrated PLC additionally enables detection of blockages in systems and can automatically alternate reverse/forward operation to free the material blockage.
Robust Solutions for Loading and Unloading
From ports and terminals to processing plants, the ability to move vast quantities of materials quickly and safely is essential for operational success. NORD provides robust, high-torque drive solutions engineered to power the most demanding loading and unloading equipment, ensuring maximum system availability and optimized performance. UNICASE helical bevel gear units offer powerful performance capable of moving large systems such as mobile ship loaders, clamshell unloaders, and bucket-wheel stacker-reclaimers, positioning them as needed to access various areas of stockyard operations. To withstand the harsh environmental conditions, gear units in these areas are additionally equipped with heavy-duty housings sealed against moisture ingress and fitted with corrosion and moisture-resistant components. Application-specific options such as dust and corrosion-protected brakes, micro-switches for continuous brake monitoring, or double canopies serving as drip covers for motor fans are also available. These features further enhance the durability of the drive systems and ensure they achieve an extended service life.
NORD’s extensive product portfolio is constantly being developed and extended. Through continuous investment in the latest development, manufacturing, and automation technology, NORD can provide their customers with drive systems optimized for the specific requirements of their industry.
