Lock Metal Detector

• Ensuring product safety and integrity in food processing lines by detecting metallic contaminants.
• Quality control in pharmaceutical manufacturing to identify foreign metal objects in tablets or capsules.
• Inspection of packaged goods in FMCG industries to prevent contaminated products reaching consumers.
• Protecting downstream machinery from damage caused by tramp metal in bulk materials.
• Recycling operations to separate ferrous and non-ferrous metals from waste streams.

Typical throughput

For this class of equipment, throughput rates are typically dependent on belt speed and product size, commonly ranging from 10 to 60 metres per minute.

Power supply

Units of this type commonly operate on standard industrial single-phase or three-phase power, typically 230V or 400V AC.

Footprint

The overall length for a conveyorised metal detector is typically between 100cm and 200cm, with widths varying based on the aperture size.

Detection sensitivity

Sensitivity for metal detectors is typically measured in millimetres for ferrous, non-ferrous, and stainless steel, varying based on product effect and aperture dimensions.

Construction material

Frames and enclosures are commonly constructed from stainless steel for hygiene and durability, particularly in food and pharmaceutical applications.

Control system

Modern units typically feature digital controls with touch-screen interfaces for easy setup and operation.

Rejection mechanism

This unit features a belt stop alarm; other common rejection mechanisms include air blast, push-arm, or diverter systems.

• What types of metal can this detector identify?

  Metal detectors of this type are designed to identify ferrous (magnetic), non-ferrous (e.g., aluminium, copper), and often stainless steel contaminants. The exact sensitivity for each type will depend on the unit's calibration and the product being inspected.

• Is this unit suitable for wet or washdown environments?

• How is the product fed through the detector?

• What maintenance is typically required for a metal detector?

• Can the sensitivity settings be adjusted?

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.
