Similar to the deflector sheet however the cones work most effectively in vertical drilling.
The idea is to produce a significantly cleaner collar and reduce the amount of fall back and regrind. This increases bit life, dependency on water and reduces the amount of dust created.
The deflector cones are made from a cut and tear resistant polyurethane that firmly seals around the drill rod. The cuttings being bailed out of the blast hole hit the cone and bounce off at an angle away from the hole.
The reason this works is the high rebound properties of polyurethane. Rather than absorb the velocity of the cuttings and have them drop straight back down choking the collar, they are deflected away.
This creates less regrinding giving you larger particle size in your cutting pile. This means you can often use your cuttings to stem holes rather than import stemming.
The other huge benefit is from an OH&S perspective. Less fine respirable/breathable dust makes a much safer environment for your drillers and ground crew.
Deflector cones will suit a wide range of drills. Alternatively we fabricate housing assemblies to hold a deflector cone and wiper.
Available in small and large.
