Design of a Turbulence Generator of Medium Consistency Pulp Pumps

Design of a Turbulence Generator of Medium Consistency Pulp Pumps

The turbulence generator is a key component of medium consistency centrifugal pulp pumps, with functions to fluidize the medium consistency pulp and to separate gas from the liquid. Structure sizes of the generator affect the hydraulic performance. The radius and the blade laying angle are two impor...
