VARI-STEM -- VARISTEM BLASTING/STEMMING PLUGS

MAXIMUM BLAST CONTAINMENT MEANS GREATER FRAGMENTATION AND MICRO-FRACTURES, WITH MORE TONNAGE PROCESSED AT LESS COST

The Varistem reduces processing costs, with the Varistem achieving up to a 25% increase in fragmentation. Studies also show the Varistem can reduce blast patterns by 10% or greater and achieve the same fragmentation for major savings in drilling and explosive costs. The "very low cost" Varistem is the most efficient means of reducing costs in blasting and processing.

The above photo sequence demonstrates how the VARISTEM effectively plugs drill holes, eliminating stemming ejection so that the total blast is directed into the body mass for maximum breakage. Although this example shows a bridge support demolition, this is this same stem locking that achieves maximum fragmentation in quarry/mine field operations. Note in the photo sequence that the body mass disintegrates with absolutely no stemming ejection!
