Tramp Metal Detectors

Protect your assets with the last line of defence

Tramp metal detectors help protect crushers and other downstream processing equipment from metal contaminants carried in the material stream. Accurate Industries partners with US manufacturer Advanced Detection Systems (ADS) to supply SurroundScan metal detection equipment for mining, quarrying and industrial processing applications.

The range detects ferrous, non-ferrous and stainless steel contaminants. With application-specific sizing and sensitivity settings, SurroundScan systems help reduce the risk of equipment damage and unplanned downtime.

Another layer of protection after magnetic separation

Tramp metal detection complements magnetic separation by identifying metal remaining in the material stream before it reaches downstream equipment. In mining and quarrying applications, detectors are often installed after magnetic separators to detect contaminants that have passed through the separation stage.

SurroundScan Protector detectors identify ferrous, non-ferrous and stainless steel tramp metal. When integrated with suitable plant controls, detection can trigger an alarm or stop equipment so operators can locate and remove the contaminant before it reaches the crusher.

Explore our magnetic separators to see how separation and detection can work together in your plant.

Detection performance depends on the application. Material characteristics, aperture size, contaminant type, size, shape and orientation, and the operating environment all influence sensitivity. Contact Accurate Industries to discuss the detection levels required for your process.

AccuLearn Technology

AccuLearn learns your material’s characteristics and adjusts sensitivity for the application. Product learning can take as little as 1–2 minutes. Detected contaminants can then be handled by the configured plant controls or separate reject equipment.

Product Monitor

With Product Monitor, you get real time signal values for your product and the tramp metal that must be detected.

Patented Auto Balance

Advanced Detection Systems' auto-balance software maintains perfect coil balance and optimum performance, eliminating the cost of a service technician plant visit to re-balance the metal detector.

Patented Vibration Technology

ProScan vibration technology monitors interference created by vibration and automatically compensates for the effect, thus enhancing reliability and sensitivity.

metal detector add-ons

optional accessories

Metal Marker

Metal marker metal detector accessory, conveyor, Mining, quarrying, Accurate Industries
A metal marker identifies the position on the belt associated with a detection event, helping operators locate the affected material for inspection and removal.

Remote control enclosure

An external control enclosure can place the controls in a more accessible position when the detector is difficult to reach or read.

Splice Sensor

splice sensor metal detector accessory, Conveyor, mining, quarrying, Accurate Industries

A splice sensor detects an approaching metal belt splice and signals the detector to temporarily adjust sensitivity as it passes. Splice size and design influence detection performance during this period and should be considered when selecting and setting up the system.

Cabinet heater

A thermostatically controlled cabinet heater is an option for cold operating conditions, helping reduce condensation and maintain touchscreen readability.

Accessory compatibility depends on the detector model and installation. Contact Accurate Industries to confirm the appropriate configuration.

tramp metal detector considerations

how to select the correct tramp metal detector

To help specify the right detector, tell us about:
  • The material being conveyed and its characteristics.
  • The type and size of metal contaminants you need to detect.
  • Conveyor belt width and speed.
  • Burden depth, lump size and troughing angle.
  • Belt splice or repair clip details.
  • Available frame clearance, idler spacing and installation space.
  • Detector location and the stopping distance before downstream equipment.
  • Operating conditions and the required alarm, conveyor-stop or reject response.

Integration with your existing conveyor

A successful installation starts with the conveyor layout. Belt width, material burden depth, troughing angle, available clearance and detector position all need to be considered when sizing the system. Protector LP and HD models use removable end plates to simplify installation on existing conveyor frames. The HD Ultra has a removable upright for installation without belt removal, with custom mounting plate adapters available to suit existing frames. Programmable contacts allow integration with plant PLCs and suitable reject equipment, including divert gates or belt ploughs. The response to a detection event should be configured for your process, whether that means stopping the conveyor or operating a separate reject device. Send us your conveyor dimensions and application details so we can help select the detector and accessories for your process.

FAQ

Tramp Metal Detectors Frequently Asked Questions

Why do I need a metal detector?
Tramp metal detectors help protect downstream processing equipment and product purity by identifying metal contaminants in the material stream. They can complement magnetic separators by detecting remaining ferrous, non-ferrous and stainless steel contaminants.
For equipment protection, place the detector ahead of the equipment at risk, allowing enough distance to stop the conveyor or remove the affected material. It is often installed after a magnetic separator. The final location must also provide the clearances required for reliable detector operation.
Material characteristics, aperture size, the metal contaminant’s type, size, shape and orientation, and the operating environment all affect sensitivity. Belt splices and the settings used to accommodate them can also affect detection performance. Confirm the required detection levels for your specific application.
Start with your material, target contaminants and conveyor layout. Restricted clearance may suit the Protector LP; demanding conveyor installations may suit the Protector HD; enhanced sensitivity may call for the HD Ultra. The Defender III addresses sensitive processing and product purity applications. Accurate Industries can help assess the appropriate model and configuration.
