Filed:

Jul 7, 2005

Appl. No.:

11/177615

Inventors:

Dean Lance Brone - Ann Arbor MI, US
Scott A. Clement - Atascadero CA, US
Bruno Caspar Hancock - North Stonington CT, US
David Bruce Hedden - Ann Arbor MI, US
Michael A. McCall - Atascadero CA, US

Thomas G. Troxel - San Luis Obispo CA, US

Assignee:

Jenike & Johanson, Inc. - Westford MA

International Classification:

G01N 33/00

US Classification:

73866

Abstract:

A bed of particulate solids is fluidized in a test chamber to yield multiple test samples for subsequent evaluation of segregation effects. A controlled stream of gas enters the chamber in a series of flow rate cycles each progressively increasing to a maximum rate of gas flow and then decreasing, the maximum rate increasing for successive cycles. An indicating function is formed from measurements of corresponding rates of gas flow and pressure across the bed. Upon termination of the fluidization, multiple samples are sequentially extracted from a single space at the bottom of the test chamber.

International Classification:

G01N 15/00

US Classification:

7386321, 738655

Abstract:

A method and apparatus enables testing of sifting segregation of a particulate solid mixture in a storage bin or hopper. The apparatus makes use of a convergently and divergently angled hopper for collecting the mixture. The apparatus further makes use of a minimally-shearing feeder mechanism supplying a desired flow of mixture, with minimal to no sifting segregation, to the angled hopper. A collection mechanism removes samples of the mixture from the angled hopper for analysis with minimal disruption of the particles of the mixture relative to each other. Thus, samples resulting from the testing apparatus, and corresponding method, are highly representative of mixture conditions within a larger storage hopper.

US Classification:

222 1, 222229, 7386356

Abstract:

A method makes use of a minimally-shearing feeder mechanism supplying a desired flow of particulate solids mixture, with minimal to no sifting segregation to a desired location. The feeder methodology maintains a uniform concentration of each size of particle within the mixture.
