In-line mill assembly with spreader ring
View Patent ↗The system and method requiring a diverter plate for an in-line mill. The plate for use with the in-line mill includes an aperture for passage of particulate laden fluid therethrough and a plurality of tabs such that the fluid and the particulate entrained thereon is deflected at a variety of axial angles. The diverter plate thus provides a reliable method such that the milling process and component wear resistance is made more efficient thereby.
1. An in-line mill for processing a pressurized, particulate-laden fluid stream and having improved durability of components including at least the particle reduction chamber, the mill comprising:
a) a rotor;
b) a casing for enclosing the rotor, the casing including a pressurized fluid inlet, a particle reduction chamber, and a fluid outlet;
c) a shaft and bearing assembly attached to the casing and supporting the rotor;
d) a drive assembly operatively connected to the shaft for rotating the rotor; and
e) a stationary, non-rotating plate mounted within the casing, the stationary, non-rotating plate comprising:
i) an aperture defined in the center thereof for receiving and passing through a portion of a particulate-laden pressurized fluid stream; and
ii) a plurality of tabs extending radially from the aperture of the stationary, non-rotating plate, the tabs being axially displaced from the aperture at a variety of angles so as to provide multiple angles of redirection for the portion of the particulate-laden fluid stream redirected by the stationary, non-rotating plate,
whereby the variety of angles of the tabs increase the variance of dispersion of particulate within the particle reduction chamber.
2. The in-line mill of claim 1 , wherein the aperture of the stationary, non-rotating plate has a circular profile.
3. The in-line mill of claim 1 , wherein the aperture of the stationary, non-rotating plate has a saw toothed profile.
4. The in-line mill of claim 1 , wherein the stationary, non-rotating plate is mounted to a wall of the casing.
5. The in-line mill of claim 1 further including at least a second plate axially displaced from the stationary, non-rotating plate to further increase the degree of variance of particulate dispersion within the in-line mill.
