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…
Conveyor Protection- Emotron M20 Shaft Power Monitor
Application problem: The client’s conveyors had no monitoring. As a result any blockage lead to large volumes of material backing up on the conveyor until drive motor trips due to thermal overload. This leads to production downtimes as an intervention is required to clear the backlog. Excessive mechanical load on the conveyor results in reduced…
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…
Crane Collision Protection – Hawk Measurement Microwave Switch
Application problem: 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 by…
Cement Powder Silo Level Measurement – Hawk Measurement Sultan Acoustic Level
Application problem: Each silo contains cement of particular type specifications. One or several silos will contain a particular type of cement product. Most manufacturers or shippers of cement powder will have multiple storage silo level applications. Bins are generally fed pneumatically, or via air slide from a process or delivery vehicle. Product is normally removed…
Cement Silo Level Detection – Hawk Measurement Admittance Switch
Application problem: High level alarms were required for cement bins in freezing conditions prone to probe build-up. Vibrating fork style switches suffered from build-up and were not rugged enough for these conditions. One other important thing is that the moisture of the different materials can vary a lot from time to time that is a…
