Brick Manufacturing Plant – Blocked Chute Detection
Application problem: The brick manufacturer was experiencing blockages during the production process at the base of their feed hopper, resulting in costly production delays and plant shutdowns to clear the material. Solution: Utilising HAWK Gladiator Admittance Switch technology proven for these applications, the Gladiator remote variant (controller and probe separated) was selected allowing the controller…
Boom and Blocked Chute Protection – Hawk Microwave Switch
Application problem: 1. The customer had previously used lanyard rope switches, to protect the boom on stacker/reclaimers, from coming in contact with stockpiles. Lanyard rope switches, require high maintenance support, to keep them operational. If the lanyard rope is not tensioned properly, the system will not work. Brackets supporting the lanyard rope were frequently bent…
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…
Blocked Chute Protection – Hawk Measurement Gladiator Microwave Switch
Application problem: The customer had problems getting early enough indication of blocked chute on a critical application on a feeder to vibrating screen with mixed particle sizes. Speed of response was critical and probes proved unsuitable, because “on” delays had to be used to overcome intermittent impact by the product on the probes. The customer…
Predictive Maintenance – Hawk Measurement Microwave Switch.
World’s First Microwave Switch that can be used to PREDICT blockage / build-up saving considerable downtime. Profitably is directly linked to reliably and productivity. This why historically HAWK Gen 3 Microwaves have been installed to reduce downtime from false trip as these switches are able to punch through considerable amount of build up before they…
Why Acoustic level technology is superior to Radar technology in wet and difficult applications
Application problem: The client had installed low frequency Radar transmitters to control his ROM bin level applications. The ROM bin had water spray dust suppression installed to reduce dust problems when the truck was tipping. The Radar constantly failed because of buildup over and inside the focalizer cone. The Radar also failed when some build-up…
