Publication number: 20080029555Abstract: A minimally-shearing feeder mechanism supplies a desired flow of particulate solids mixture, with minimal to no sifting segregation, to a desired location. The feeder mechanism maintains a uniform concentration of each size of particle within the mixture.Type: ApplicationFiled: October 3, 2007Publication date: February 7, 2008Applicant: JENIKE & JOHANSON, INC.Inventors: Dean Brone, Scott Clement, Bruno Hancock, David Hedden, Michael McCall, James Prescott, Thomas Troxel

Publication number: 20080028872Abstract: 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.Type: ApplicationFiled: October 3, 2007Publication date: February 7, 2008Applicant: JENIKE & JOHANSON, INC.Inventors: Dean Brone, Scott Clement, Bruno Hancock, David Hedden, Michael McCall, James Prescott, Thomas Troxel

Publication number: 20070028705Abstract: 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.Type: ApplicationFiled: October 11, 2006Publication date: February 8, 2007Applicant: JENIKE & JOHANSON, INC.Inventors: Dean Brone, Scott Clement, Bruno Hancock, David Hedden, Michael McCall, James Prescott, Thomas Troxel

Patent number: 6910393Abstract: A powder sampling method and apparatus is provided for sampling powder from a mixer or a drum. An undisturbed column of powder is extracted from a vessel. The column of powder may then be sectioned into subunits, using a discharge device, providing up to dozens of samples per insertion. Larger number of representative samples of controlled size from a powder bed can be acquired.Type: GrantFiled: December 11, 2000Date of Patent: June 28, 2005Assignee: Rutgers, The State University of New JerseyInventors: Fernando J. Muzzio, Albert Alexander, Dean Brone, Michael Roddy

Patent number: 5938330Abstract: A study was done to compare the performance of a conventional V-blender to a V-blender that incorporates perturbations of the particle flow by rocking the mixing vessel during its normal rotation. Mixing was investigated using glass beads with sizes from 66.mu. to 600.mu. in vessels of approximately one liter volume. Mixture uniformity was assessed qualitatively, using two different methods. One method involved a transparent mixing vessel where it was possible to see particle flow patterns and assess the state of the mixture at its surface during the entire experiment. The second method involved disposable aluminum mixing vessels, where the mixture was solidified by infiltrating the mixture with a binder. By slicing the solidified structure, it was possible to assess the entire state of the mixture including its interior structure after the completion of each experiment. Mixture uniformity was also assessed quantitatively using image analysis of the slices.Type: GrantFiled: January 5, 1998Date of Patent: August 17, 1999Assignees: Merck & Co., Inc., Rutgers, The State University of New JerseyInventors: Priscilla A.
