ELIZABETH CITY, NC - Hockmeyer has been awarded patent rights to an extension of the technology approved in its sixth patent covering the use of polymeric material to create a containment wall capable of holding grinding media as small as .025mm in diameter. This new patent covers the use of sintered porous metal as the separation device. Although polymeric materials have substantial benefits, the addition of a sintered metal option adds the ability to operate at much higher temperatures and in those rare cases where a solvent in the feedstock may not be compatible with the polymeric containment wall, while retaining all the benefits of wear resistance and durability. atent Number 7,883,036 was granted on February 8, 2011.
