Cyclone separator is a kind of equipment that USES rotary motion of gas-solid two-phase fluid to make the solid particle separated from the gas flow by centrifugal force.

But such as short circuit flow, up ash loop, re-entrainment exists and so on phenomenon, made the solid particle couldn't be separated efficiently, so reduced separation efficiency of the cyclone.

On the basis of test results of artificial rockfill materials with different particle strength, the breakage volumetric strain of artificial rockfill materials was separated successfully.
