Spiral Concentrator For Coal

Spirals in coal processing are high capacity, lightweight fiberglass construction, use no power, use no reagents and effectively remove pyrites from coal. Most spirals are available in single start, double start or triple start versions, giving two or three times the capacity for the same floor space. Single spiral test stand is also available.
