It has not earlier been technically possible to recover lime-rich mussel shells and seashells by powdering the shells. In brief, the technical solution comprises drying the shells, crushing the shells and grinding the same in a mill provided with hammers and gratings. A grinding process in which the circulating unfinished product is an important part of the system circuit. The finished product is delivered by a screw feeder to bulk or large sacks from a mobile plant constructed to this end.
