High pressure feeder deflection prevention

Abstract From the Canadian patent

A high pressure transfer device and method of continuously conveying hard particulate material using the high pressure transfer device ensure proper operation even under high pressure differential. The high pressure transfer device includes a pocketed rotor containing through-going pockets and a housing enclosing the rotor and having ports disposed around the exterior periphery of the housing. A structure, such as first and second jacket portions, is provided for applying a radially inwardly directed force to the housing exterior periphery roughly proportional to and opposite a force tending to deflect the housing radially outwardly so that significant deflection of the housing is …
