PPLM - Metal Detector

• Detecting metallic contaminants in packaged food products to ensure consumer safety and regulatory compliance.
• Inspecting bulk materials such as grains, powders, or aggregates for unwanted metal fragments.
• Quality control in pharmaceutical production to identify metal particles in tablets or capsules.
• Protecting downstream processing machinery from damage caused by tramp metal.

Typical aperture size

Varies significantly; commonly found with aperture widths from 150mm to 600mm and heights from 50mm to 300mm, depending on the product being inspected.

Power supply

Typically single-phase 230V, 50Hz, though some larger industrial units may require three-phase power.

Detection sensitivity

For this class of equipment, sensitivity is typically in the range of 0.5mm to 3.0mm for ferrous, non-ferrous, and stainless steel contaminants, depending on the product effect.

Conveyor speed

Commonly adjustable, with typical speeds ranging from 10 to 60 metres per minute, suited to integration with existing production lines.

Construction material

Units are typically constructed from stainless steel (grade 304 or 316) for hygiene and durability, especially in food and pharmaceutical applications.

Environmental rating

Many units are rated to IP65 or higher, indicating suitability for washdown environments.

• What types of metal can this equipment detect?

  Metal detectors are designed to identify ferrous (iron, steel), non-ferrous (aluminium, copper, brass), and non-magnetic stainless steel contaminants. The sensitivity for each type can vary.

• How does a used metal detector compare to a new one?

• Is calibration necessary for a metal detector?

• Can this metal detector be integrated into an existing production line?

• What maintenance is typically required for a metal detector?

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.
