FIELD: process engineering.
SUBSTANCE: invention relates to production of non-explosive limestone-based disintegrating means used for production of natural stone and reduced-impact destruction of construction structures and objects to be withdrawn from service. Non-explosive disintegrator is produced by limestone sintering, limestone being crushed, mixed with crushed solid fuel, pelletised and sintered in appropriate unit. Sintered product is crushed to definite particle size and mixed at preset ratio with cement. Gypsum stone in amount of 1-3 wt % of limestone is added thereto while solid fuel is composed of sulphur oil coke with sulphur content of up to 9%.
EFFECT: notable acceleration of non-explosive disintegrator expansion.
