Safeline - Metal Detector

• Detecting metallic contaminants in bulk food products such as grains, powders, and snacks.
• Ensuring product safety and quality in pharmaceutical manufacturing by identifying metal fragments.
• Protecting downstream processing machinery from damage caused by tramp metal.
• Quality control in non-food industries like plastics, textiles, and recycling to remove metallic impurities.

Typical throughput

For this class of equipment, throughput can vary significantly based on product density and line speed, but units are commonly designed for continuous operation.

Power supply

Industrial metal detectors typically require a 3-phase electrical supply, commonly 400V or 415V, 50Hz in the UK.

Aperture size

Units of this type commonly feature a rectangular aperture, with dimensions varying to suit specific product sizes and conveyor widths.

Detection sensitivity

Modern industrial metal detectors are typically capable of detecting ferrous, non-ferrous, and stainless steel contaminants, with sensitivity depending on aperture size and product effect.

Reject system

Commonly, these systems integrate with an automatic reject mechanism, such as an alarm and belt stop, to remove contaminated product from the line.

Construction material

For hygiene and durability, the frame and contact parts are typically constructed from stainless steel.

• What types of metal can this detect?

  Industrial metal detectors are typically designed to detect ferrous (magnetic), non-ferrous (e.g., aluminium, copper), and some grades of stainless steel contaminants. The exact sensitivity for each type will depend on the unit's configuration and the product being inspected.

• How does the reject system work?

• Is this suitable for wet or dry products?

• What maintenance is typically required?

• Can this unit be integrated into an existing production line?

Metal detectors for food processing remain reliable workhorses in quality control operations. Buyers typically value their durability and consistent contamination detection capability. When purchasing used units, inspecting calibration history and sensitivity settings proves essential. Industry sentiment favours machines with straightforward maintenance records and minimal downtime. Common strengths include robust construction, straightforward operation, and cost-effectiveness compared to new equipment. Prospective buyers should verify functional testing documentation and assess integration compatibility with existing production lines.
