Metal detector can detect which metal impurities

For a production enterprise, no matter how strict the management is, it is difficult to completely eliminate metal impurities, because our production equipment is metal, and most production processes are not closed. The metal detector is specifically used to detect these metal impurities, so how are the metal impurities in the product mixed?

Sources of metal impurities:

1. Human factors are mixed, mainly including buttons, jewelry, coins, keys, hairpins, pushpins, pins, utility knives, etc .;

2. Mixed from raw materials, such as metal labels and needles mixed in meat products, metal wires mixed in flour, broken wire mesh mixed in powder materials, knives mixed in vegetables, etc .;

3. Due to the manufacturing process of the enterprise, such as grinding machines, mixing mixers, slicers, and metal parts in contact with transmission, metal fragments, iron filings, nuts, screws, etc. due to looseness, wear, and fracture;

4. Caused by daily maintenance, such as missing screwdrivers, wrenches and other maintenance tools, cutting metal chips, welding slag, metal scraps generated during the maintenance process.

These metal impurities can not be eliminated by manual, so it is necessary to install a metal detector to detect before the product is packaged, to exclude products containing metal impurities, so as to ensure product safety.
