Abstract:
1. A hydrocyclone comprising: a first section having a first casing and a first liner which is disposed radially inwardly of the first casing; a second section having a second casing and a second liner which is disposed radially inwardly of the second casing; a receiving portion comprising an annular groove provided in said first and second casings; a radially inner portion of the receiving portion being defined by radially outwardly facing surfaces of the first and second liners; a radially outer portion of the receiving portion being defined by radially inwardly facing surfaces of the first and second casings; an upper portion of the receiving portion being defined by a surface of the first casing; and a lower portion of the receiving portion being defined by a surface of the second casing; thereby defining a cavity for an annular energy diffusion ring to reside, and, an annular energy diffusion ring situated in said receiving portion, the annular energy diffusion ring comprising a resilient suspension matrix of at least one of a polymer or elastomer which is configured to be sacrificed by erosion during use, and a plurality of closely-packed hard inserts suspended within said resilient suspension matrix; wherein in use, the annular energy diffusion ring is configured to diffuse slurry passing between said first liner and said second liner before it reaches a portion of the first or second casing.
