Quarry & Aggregate Applications

Maximising productivity and reducing downtime using: Blocked chute detection, Flow / no-flow monitoring, Level Measurement in Silos Tanks and Bins, and motor control and protection. Communicated via Local or Remote monitoring via Alarm panels, DSC and SCADA.

Gypsum Powder Silo Level Measurement - Hawk Centurion Guide Wave Radar

Gypsum Powder Silo Level Measurement – Hawk Centurion Guide Wave Radar

Application problem: Gypsum silos undergo a pyrolysis reaction in an environment which experiences unusually fast corrosion due to both temperature and the presence of an electrolyte solution (CaCl). Due to both the temperature and the presence of a large agitator the process was deemed unsuitable for ultrasonic measurement and large amounts of suspended dust particles…

Boom and Blocked Chute Protection - Hawk Microwave Switch

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

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

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

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 Protection Monitor

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…

Acoustic Level Measurement Superior to Radar

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…

Cement Powder Silo Level Measurement - Hawk Measurement Sultan Acoustic Level

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…
