The World’s Quietest Blast Nozzles
• 45% Less Thrust!
With more than 20 years in the industry, Hort Enterprises has evolved from an engineering support business for the local agricultural sector to become a full-scale engineering operation with strong links to the mining sector throughout Regional NSW. Hort Enterprises boasts superior surface finishes with the knowledge, the skills and the equipment to get the job done right the first time.
With the launch of BlastOne’s new SnakeBite nozzle, Hort Enterprises wanted to test its efficiency. Together, we hosted a trial comparing a #7 BlastOne Ultra Tuff nozzle to the new SnakeBite XQ #7 nozzle. The trials focused on production rate and noise level. Additionally, abrasive consumption rates were also calculated to showcase overall cost.
BlastOne and Hort Enterprises conducted a study to determine whether the SnakeBite would reduce blasting noise without reducing productivity. Blasting a flat panel divided into two sections with a thick 1000 micron coating, here is how the #7 Ultra Tuff compared to the SnakeBite XQ:
|Nozzle||Nozzle Pressure||Test Area||Blast Time||Blasting Speed||Sound Reading|
|#7 Ultra Tuff||100 psi||30.25 m2||104 s||10.49 m2/hr||102 dBA|
|SnakeBite XQ*||100 psi||29.67 m2||81 s||13.15 m2/hr||90 dBA|
|Nozzle||#7 Ultra Tuff||SnakeBite XQ*|
|Nozzle Pressure||100 psi||100 psi|
|Test Area||30.25 m2||29.67 m2|
|Blast Time||104 s||81 s|
Unfortunately, at the time, no sound readings were taken from further away, outside of the blast room. The difference in noise is even more obvious when you move further away.
Using the True Cost Abrasive Blasting Formula, we calculated the amount of abrasive used per square metre by each nozzle.
|Nozzle||Consumption Rate||Abrasive Purchase Cost Delivered||Abrasive Disposal Cost||Labor and Equipment Cost||Production Rate||Blasting Costs|
|#7 Ultra Tuff||.48 t/hr||$918/t||$100/t||$140/hr||10.49 m2/hr||$67.55 per m2|
|SnakeBite Strike||.48 t/hr||$918/t||$100/t||$140/hr||13.15 m2/hr||$54.66 per m2|
|Nozzle||#7 Ultra Tuff||SnakeBite Strike|
|Consumption Rate||.48 t/hr||.48 t/hr|
|Abrasive Purchase Cost||$695/t||$695/t|
|Abrasive Disposal Cost||$50/t||$50/t|
|Labor and Equipment Cost||
$9.23 per m2
$5.77 per m2
Our estimates show that the SnakeBite XQ is not only quieter than the #7 Ultra but it’s high productivity results in $12.89 less abrasive used per square metre. Over 1000 square metres, that is $1,289 back in your pocket!
Blasting speed increased by 25% which is half a day extra of blasting each week.
Sound level was almost halved, which improved the surrounding environment for nearby workers and prevented disrupting workflows. While the SnakeBite XQ was in action, the noise was significantly reduced and a normal conversation (80dBA) could happen during blasting.
The Snakebite XQ is the worlds quietest blast nozzle. Designed and manufactured by BlastOne, this product effectively reduces the noise pollution of blasting by 75% and also reduces the operator fatigue up to 45% due to its low kick-back-thrust design. Truly a game changer for abrasive blasters.
The SnakeBite XQ reduces noise generated by up to 16 dBA – that’s equivalent to up to 75% quieter than standard nozzles, and the typical high pitched screech is now gone.
With its reduced noise capabilities, SnakeBite XQ allows other crews to work in the vicinity of blasting, minimizing production disruptions.
The unique design of nozzle and silencer reduces operator fatigue by up to 45%. Operators can better maneuver the nozzle and will be less fatigued over the shift.
Productivity of the Flex is comparable with standard nozzles (same size, pressure, media) and the XQ is up to 25% more productive than standard nozzles of the same size. The reduced nozzle kick-back thrust – up to 45% – can actually increase productivity by reducing operator fatigue and enabling a high rate of productivity to continue throughout the shift…. and the #10 Strike (due to the larger orifice size) can increase hand-held blasting productivity up to 54%.
Adjusting these factors will have an effect on dB reduction.
