Mascot ultra search gravity feed metal detection system is designed to inspect any free flowing bulk powder or granular materials grains, pellets, flakes, etc. Any free flowing materials may be passed through the vertical drop system. The unit fits into an existing pipeline or beneath a feed hopper and the product fall by gravity. The metal free prod passes straight into the mechanism and diverts the ferrous/non ferrous and stainless steel contamination from the main flow. Typical places of installation for free-fall separators are a fall-pipe, at belt transfer position, below cyclone or hopper, or before bagging machine. It finds application in pharmaceutical, food process industries, paper mills, soap industries, chemical, rubber, etc.
