    2005-12-1 · In an attempt to identify the effect of aggregate stemming on mill throughput, production data from January 1–8, May 2002 were analyzed, representing Stockpiles 183–187. SP 183 and 184 were prepared from blast shots with drill cuttings as stemming, whereas SP 186 and 187 had aggregate stemming in the shots.

  • Influence of aggregate stemming in blasting on the

    A secondary but important benefit to come out of the change in stemming practice has been the reduced wear in the gyratory crusher, resulting in a significantly longer period between relines. This paper compares the key mill performance indicators when the mine moved from drill cuttings to aggregate as stemming in the blast holes.

  • Granulated Blast Furnace Slag an overview

    The blast furnace cement (CEM III) in Table 4.1 is so-called low early-strength cement, indicated by L. Low early-strength CEM III cement conforming to the requirements in Table 4.2 can also be designated sulphate-resistant common cement. Common cement with blast furnace slag often has LH in its designation, which implies low heat of hydration.

    capable of being made into an aggregate. . . Mill's argument would hold if the minds of all human beings were to be rolled into one, so as to form an aggregate. But as it is, ' the aggregate of all persons' is nobody, and consequently nothing can be a good to him. A good must be a good for somebody." 3
