ArdeeSort
The ArdeeSort Dry Coal Deshaling System is an advanced sensor-based dry beneficiation solution that removes high-ash shale, stone, and other inorganic impurities from coal without using water or chemicals. Designed for coal mines, washeries, thermal power plants, steel plants, cement plants, and other industrial coal processing facilities, the modular system delivers cleaner coal, lower operating costs, improved fuel quality, and environmentally sustainable operation.
Key Features
Advanced Sensor-Based Coal Beneficiation
High-speed DE-XRT technology analyzes every individual coal particle and precisely ejects high-ash impurities for superior separation efficiency.
Completely Dry & Environmentally Sustainable
Operates without water, chemicals, tailings, or effluent generation, providing a cleaner and more sustainable alternative to conventional coal washing.
Modular Solution for Multiple Industries
Suitable for coal mines, washeries, thermal power plants, steel plants, cement plants, industrial boilers, and lignite beneficiation, with scalable fixed or mobile installations.
Lower Total Cost of Ownership
Combines low CAPEX, very low OPEX, compact footprint, minimal maintenance, and improved fuel quality to maximize long-term operational savings and return on investment.
ArdeeSort is an advanced dry beneficiation technology that utilizes dual-energy X-ray transmission (DE-XRT) principles to distinguish organic coal from inorganic mineral matter on a particle-by-particle basis. As material passes through the sorting modules, each particle is scanned using high-speed X-ray sensors that analyze differences in attenuation caused by variations in elemental composition. Sophisticated processing algorithms evaluate the ash-to-organic ratio of every individual particle within microseconds, after which precision pneumatic ejectors remove high-ash material from the product stream.
The complete system typically begins with primary crushing using Ardee's Rotary Breaker HE Series or other suitable crushing equipment, followed by screening to produce the desired feed fractions. The sized material is then processed through modular ArdeeSort units that separate clean coal from shale and stone without consuming water or generating slurry. Depending on the application, the recovered clean coal can be directed to stockpiles, washery circuits, thermal power stations, coking plants, cement kilns, or industrial boilers, while rejected high-ash material can be disposed of or utilized separately.
Unlike conventional wet coal washing, ArdeeSort does not rely on dense media, magnetite, flotation chemicals, or water-intensive separation processes. The technology produces no tailings or effluent, requires only a compact installation footprint, and can be deployed as fixed, skid-mounted, or trailer-mounted modules for permanent or mobile operations. This flexibility allows the system to be integrated into new installations or retrofitted into existing coal processing facilities with minimal disruption.
ArdeeSort is particularly valuable wherever reducing ash content improves downstream performance. Mining companies benefit from transporting less waste rock, coal washeries receive a cleaner feed, thermal power plants achieve improved combustion efficiency and reduced ash handling, while steel and cement manufacturers benefit from more consistent fuel quality and lower operating costs. Its modular architecture also enables capacity expansion as production requirements increase, making ArdeeSort a scalable solution for a broad range of coal beneficiation applications.
