FIELD: recovery of waste roofing bitumen -containing materials.
SUBSTANCE: method comprises steps of preliminarily cutting material by pieces; feeding it to chamber of disintegrating apparatus; disintegrating material by means of dull cutters; sorting disintegrated material by bitumen powder and bitumen cardboard; at disintegration adding to material water in quantity consisting 1-15 mass % of processed material; providing high -speed rotation of cutters for creating fine-drop mist covering disintegrated material in order to eliminate its sticking onto inner surfaces of disintegrating chamber; trapping dust-like bitumen formed at disintegration process and melting it together with bitumen powder and simultaneously dehydrating it. It is possible to dissolve detergent in water.
EFFECT: lowered cost price of bitumen processing procedure.
