DEVICE FOR EROSIONAL CRUSHING OF ROCK BY HYDRAULIC GIANT

摘要

FIELD: mining industry. SUBSTANCE: hydraulic giant head-piece is made for possible installing in socket of drilling bit and is provided with diffuser pipe having mixing chamber. Made in hydraulic giant head-piece is calibrating hole. Accelerating section and holes for ejection are provided in diffuser pipe. Internal edge of holes for ejection are located in plane of jet discharge from hydraulic giant head-piece. Aforesaid embodiment of device increases hydraulic power of flooded jet due to utilization of erosional crushing phenomenon by sludge of drilled rock being ejected. EFFECT: higher efficiency. 1 dwg
