Sand slinger is a machine which delivers moulding aggregate and fills moulds at a high speed by centrifugal force. As the mould is filled with the aggregate, it is at the same time compacted by its own kinetic energy. The basic working part of the sand slinger is a sand-slinging head, a housing that contains a rotor with a blade.
