GEAR-UP
For Improved Blast Performance, Fly
Rock Control,
Savings in Secondary Breakage and Downstream Costs.
Use the Plugs with the Patented GEAR Design!
Just a few dollars invested in VARI-STEM Plugs
would have greatly reduced the oversized rock in the photo below, as well as
reduced the average total rock size of the muck pile.

rock from muck pile. (No VARI-STEM Used)
Left: Breaker costs are reduced with VARI-STEM.
Below: VARI-STEM reduces delays due to oversized at the crusher. |

Besides reducing average rock diameter in the muck pile, VARI-STEM saves
equipment and labor costs by reducing the quantity of oversized cap rock. It is
possible to reduce stemming height using VARI-STEM, allowing more ANFO for
greater cap rock breakage. VARI-STEM and ANFO are cheap compared to secondary
breakage costs (chemical vs. mechanical costs).
SAVINGS IN THOUSANDS OF
DOLLARS FROM A SINGLE BLAST!
Do you conduct your own in-house
Blasting?
Do you Contract your Blasting out?
Are you a Blasting Contractor?
Regardless of what side of the table you sit
at, oversized rock, especially from hard cap rock, is everyone’s problem, not
just the quarry’s!
GREATER ROCK FRAGMENTATION
130% Time Reduction in Stemming Movement
27% Reduction in Average Rock Size
Greater Tonnage Throughput at Primary Crusher
VARI-STEM Plugs are often referred to as:
blast control plugs, blast containment plugs, blast improvement plugs, blast
plugs, blasthole plugs, borehole plugs, safety hole plugs, stemming plugs or
stemming enhancers. No matter what name you might refer to them by, they are an
invaluable blasting accessory or blasting supply for blaster’s to keep in
their toolkit. They have been proven to help blaster’s do a better and safer
job.
