Coal Spiral

In your fine coal washing circuits, achieving a sharper separation means reducing your coal product loss and gaining better yields of low-ash coal.

Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a low-ash coal product at high efficiency. The high-performance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH (1.8 mtph to 2.7 mtph) per start, dependent on raw coal quality and refuse amount to be discarded. Optimum spiral feed size is -1 mm to 0.15 mm (14 M x 100 M).

  • Simple, efficient and cost-effective
  • Reduced product misplacement
  • Longer wear life
