Metal detector
Thread Content
Has anyone used a metal detector on conveyor belts for powdered products? What was the results? Could you share any relevant experience?
For powder or granular materials, a drop-type metal detector is generally the preferred choice; it is one of the three main types of metal detectors and represents a mature product It depends specifically on your materials and the level of precision you require. The type of material is relevant to the effects of the product, and it determines whether a metal detector is suitable; however, many powder and granular materials work well.

Sensing in this area is one aspect; the key is to remove the metal. I wonder what type of metal it is? Can I add an electromagnet?
Generally, strong magnets are used to remove it directly. Why bother with testing? For the processes I’ve encountered, magnets are usually used directly to remove it.
I have previously worked on thermoplastic finished products. There is a device for automatically detecting impurity particles; bright white light is emitted from the bottom, and there are detection devices at the top as the film passes by. If any black spots are detected, an alarm is triggered automatically to enable prompt action ； Generally, for testing purposes, such items are taken to the molding workshop for inspection; from chemical synthesis to packaging, various processes are used to remove impurities
For the remover, it’s mostly just a flip mechanism! Generally, aside from small devices like drug testing machines, those that don’t use electromagnets are mostly pneumatic!
