METHOD OF PREPARATION OF CAST HARDENING INSERTION IN BALL MILL Russian patent published in 1994 - IPC

FIELD: mining art. SUBSTANCE: method involves blocking used up hollows by feeding hardening mixtures through pipe-lines. For this purpose are used casting hardening mixtures with the ratio of hard to liquid (H: L) being equal to 3: 1 and containing binding agent which is composition of finely ground components capable in case of relative engagement of hydration to form solid stone. Process of insertion hardening depends considerably on class (-0.88 mm) available in mixture and on content of components in this class participating in hydration reaction. The given method provides regulation of egress of active components in class (-0.08) during preparation of insertion and obtaining as a result of it of more qualitative mixture with simultaneous reduced consumption of more expensive components and their substitution by cheaper components. EFFECT: higher quality of mixture, reduced costs of its production. 3 cl, 1 dwg, 4 tbl
