Blocked Chute Protection for Wet Applications – Hawk Gladiator Acoustic Switch

Application problem:

The mine had used mechanical tilt switches to detect blocked chute problems in conveyor transfer, chutes, screens etc.
Wet fine ore had built-up on the tilt switch and made it inoperable. The switch was not fail-safe and so when a blocked chute did occur the tilt switch did not operate, causing lost time to production.

 

Solution:

Because the ore was wet at different times we had to use our Gladiator Acoustic Switch which has the added feature of Self Cleaning to remove wet, sticky ore fines that build-up on the face of the transducers. The acoustic switch is fully fail-safe and designed to work in chutes where high water levels and ore fines are predominantly found. Each transducer uses the pressure wave affect to remove moisture and build-up. The transducers can be installed up to 700 meters away from the remote Gladiator amplifier. Hawk manufactures acoustic, microwave and admittance type blocked chute technology. All can be provided with communication protocols Foundation Fieldbus, Profibus
PA, DP, HART etc.
Hawk manufactures blocked chute technology for coal, iron ore, copper, alumina, zinc, lead, uranium etc.
