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.

Top: Expensive separation of oversized 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.
