    Sur la fragmentation de la roche

    DBA Consulting[1] / MREL tests a approfondi les tests MREL pour donner des données quantifiables sur les performances du VARISTEM® sur la fragmentation rocheuse, la capacité de rendement du concasseur et la maitrise de l'onde de choc


    The study revealed our plugs slowed stemming movement 130%, directing the blast energy into the rock, not up the bore hole. The plugs also decreased the mean average rock size in the post blast muck pile by 27%, which resulted in a 25 tons/hour increase of limestone through the primary crusher.

    DBA did a computer analysis of "every truckload" of rock taken to the primary crusher. This was a 100% muck pile study, and did not rely on carefully selected, biased photos of a muck pile. It is also more reliable than "eye balling" the surface of the muck pile.
    The DBA Study confirmed our VARISTEM® Plugs effectively contained expanding gases approximately 3 times longer than bore holes stemmed with crushed stone only.
