Study on Separation of TNT From Waste or Obsolete TNT/ RDX/Al Explosive by Melting Centrifugal Method

In order to recycle the valuable ingredients in the waste or obsolete TNT/RDX/Al explosive by low-cost method and simple operation, according to the difference of melting point among TNT, RDX and aluminum powder, a method for separating TNT from molten TNT/RDX/Al explosive by centrifugal field is designed. The results show that the optimal conditions for separation are:temperature 85℃~90℃, rotation speed 2 500~3 000 r/min, duration 30~40 min; The TNT recovery by centrifugation is 79% to 82%, and the purity is 95% to 98%.
