Eriez metal detector protects crushers, screens, and conveyor belts from damaging materials

Eriez has launched the MetAlarm metal detector tailored for the aggregates sector. The MetAlarm was developed based on direct operator input to meet the needs of the aggregates industry. 

The MetAlarm metal detector is specifically designed for installation in fixed-site quarries and mobile crushing plants. Its detection algorithms are optimized to reliably detect damaging iron and manganese steel, providing protection for crushers, screens, and conveyor belts.

In collaboration with Cardiff University, Eriez developed the MetAlarm with the capability to address challenges in the aggregates industry. By automating metal detection, the MetAlarm increases productivity and profitability while mitigating health and safety risks associated with manual inspection of hazardous materials. 

MetAlarm prototype testing has garnered positive feedback. Heidelberg Materials reported a significant reduction in equipment downtime due to blockages at its quarry near Pontypridd, Wales. This improvement has boosted production and throughput, leading to substantial cost and time savings. 

"The MetAlarm has greatly exceeded our expectations not only in terms of performance and reliability but also in driving better process efficiencies," says Mike Wilkes, general foreman for the Craig yr Hesg quarry at Heidelberg Materials. "Eriez has been a truly invaluable partner, tailoring solutions to suit our specific needs and providing customer service that is second to none." 

The MetAlarm will be officially unveiled at Hillhead 2024.
