  • Process for producing homogeneous structure abrasives
    Patent number: 5478510
    Abstract: A process for the production of abrasive materials by pouring molten abrasive material into the spaces between plates of an assembly of moving cooling plates. The pour is followed by solidification and removal of the poured material (and size reduction of the removed material). The plates are maintained parallel and vertical throughout the pouring, solidification and removal steps, the latter being accomplished by separation of the plates by a conversion wheel. The motion of the plates is then reversed by the wheel to reassemble the plates for a new cycle of pour, solidification and removal.
