Abstract
Abstract A centrifuge includes a centrifugal drum, a deflector plate for directing the centrifuged material from the drum, and a circumferential baffle plate assembly enveloping the deflector plate. The baffle plate assembly rotates in the same direction as the drum and absorbs the kinetic energy of the centrifugal material in such a way as to minimize damage to the material.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
A centrifuge for use in centrifuging particulate matter including a centrifugal drum, a deflector plate for causing at least a portion of the contents of the drum to be expelled outwardly from the drum, a circumferential spaced baffle plate assembly surrounding said plate for absorbing the kinetic energy of the material expelled from the drum, said baffle plate assembly including a supporting annular frame and a multiplicity of similarly curved, spaced-apart baffle plates secured to an inner surface of said annular frame, said baffle plates extending toward the axis of rotation of said drum adjacent said deflector plate and each having an outer convex surface facing the direction of rotation of said drum and an inner concave surface facing opposite the direction of rotation of said drum, said innEr concave surface forming kinetic energy absorbing means of material expelled from said deflector plate, means for rotating said drum and means for rotating said assembly in the same direction as said drum rotates.
Claim 2
Dependent Claim
162 words
A centrifuge for use in centrifuging particulate matter including a centrifugal drum, a deflector plate for causing at least a portion of the contents of the drum to be expelled outwardly from the drum, a circumferential spaced baffle plate assembly surrounding said plate for absorbing the kinetic energy of the material expelled from the drum, said baffle plate assembly including a supporting annular frame and a multiplicity of similarly curved, spaced-apart baffle plates secured to an inner surface of said annular frame, said baffle plates extending toward the axis of rotation of said drum adjacent said deflector plate and each having an outer convex surface facing the direction of rotation of said drum and an inner concave surface facing opposite the direction of rotation of said drum, said innEr concave surface forming kinetic energy absorbing means of material expelled from said deflector plate, means for rotating said drum and means for rotating said assembly in the same direction as said drum rotates.
Claim 3
Dependent Claim
26 words
A centrifuge according to claim 1, wherein the axes of curvature of said baffle plates are substantially parallel to the axis of rotation of said drum.
Claim 4
Dependent Claim
18 words
