Abstract
A crusher includes a housing having an inlet and an outlet at opposite axial sides, an impeller positioned proximate the inlet of the housing, and a shaft connected to the impeller and extending axially through the housing between the inlet and the outlet. At least two spaced apart support structures hold the shaft in the housing, where a plurality of dynamic blades extending outwardly from the shaft are alternatingly positioned between a plurality of fixed blades extending radially inward from an inner wall of the housing.
Claims12
A crusher, comprising:
- a housing having an inlet and an outlet at opposite axial sides;
- an impeller positioned proximate the inlet of the housing;
- a shaft connected to the impeller and extending axially through the housing between the inlet and the outlet;
- a plurality of dynamic blades extending outwardly from the shaft;
- a first support structure fixed within the housing proximate the outlet and a second support structure fixed within the housing interior to the impeller;
- wherein the first support structure and the second support structure have a plurality of flow paths formed therethrough;
- wherein the shaft extends through a bearing assembly provided in each of the first support structure and the second support structure;
- and
- wherein the plurality of dynamic blades is positioned between the first support structure and the second support structure;
- and
- a plurality of fixed blades provided along an inner wall of the housing and positioned between the first support structure and the second support structure.

A crusher, comprising:
- a housing having an inlet and an outlet at opposite axial sides;
- an impeller positioned proximate the inlet of the housing;
- a shaft connected to the impeller and extending axially through the housing between the inlet and the outlet, such that the shaft is housed entirely within the housing;
- at least two spaced apart support structures holding the shaft in the housing, wherein the at least two support structures each extend a radial distance from the shaft to an inner wall of the housing;
- and
- a plurality of blades, comprising:
- dynamic blades extending outwardly from the shaft;
- and
- fixed blades extending radially inward from the inner wall of the housing and alternatingly positioned between the dynamic blades,
- wherein a fluid flowing from the inlet through the outlet of the housing induces rotation of the impeller.
