Metal shavings, nuts, pins, nails, can sometimes contaminate the raw material. For this reason, we have created a whole programme of ferric particles detection systems, designed for protecting grinders and getting rid of iron particles in manufacturing process. There is a wide variety of applications. The main ones are used in the tinned food sector, ceramics and tiles, chemical industry, mining, the pharmaceutical industry, recycling, etc… These systems, separators, filter bars, drums, etc..., may be produced in different magnet qualities, depending on the degree of ferrous particles chosen.
