SUBSTANCE: : invention relates to environment protection, in particular to purification of rubble and/or asbestos rail ballast from pollution with oil and can be used on rail transport. Siftings of rubble and/or asbestos rail ballast are loaded into device for washing. Washing of ballast siftings is carried out by mechanical mixing with detergent solution. After washing ballast siftings and polluted detergent solution are removed together and separated. During separation ballast siftings are separated into fractions and removed in order to be used in proper way. Separated polluted detergent solution is supplied through nozzles into precipitation tank of centrifugal type for pollution by separating phases. From precipitation tank separated oil products, detergent and sludge are removed in separate flows. Sludge is dehydrated and after that neutralised using chemical reagents. Detergent solution is subjected to purification from heavy metal salts and residual oil products. Formed deposit of heavy metal salts is periodically removed to the stage of sludge neutralisation. Purified detergent solution is supplied again to the stage of mechanical washing of ballast siftings. Before supplying detergent solution to the stage of washing, technical detergent which does not require water heating is introduced into it.

EFFECT: high degree of ballast siftings purification is achieved with simultaneous efficient phase separation, reduction of dangerous wastes formation and energy consumption for the process.
