For production enterprises, no matter how strict the management is, it is difficult to completely eliminate metal impurities, because our production equipment is metal, and most of the 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, artificial factors, mainly buttons, jewelry, coins, keys, hairpins, thumbtacks, pins, utility knives, etc .;
2, mixed with raw materials, such as metal labels and needles mixed in meat foods, metal wires mixed in flour, broken wire meshes mixed in powder materials, knives mixed in vegetables, etc;
3, caused by the manufacturing process of the enterprise, such as grinding machines, mixers, slicers, and metal parts that are in contact with the 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 detection machine to detect before the product is packaged, to exclude products containing metal impurities, so as to ensure product safety.
