Improved Blast Performance -- Savings In Downstream Costs

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. Independent studies also show the VARISTEM can increase blast patterns 10% and greater, with 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.

This video shows a side-by-side comparison of two blasts --- one section with VARISTEM plugs (left), and one without(right). The Varistem provided better blast confinement, with energy directed into the ore mass for better fragmentation, crusher output, and maximum blast control (less fly rock, noise, and dust).

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!
