Patent number: 8807346Abstract: This invention relates to a centrifugal jig comprising a rotating device, at least one jig unit and a product receiver. The jig unit includes a hutch chamber, a screen residue chamber, a screen, a feeding device, a discharging device and a pulsator. The jig unit is installed on the rotor at an inclined angle along the movement of the feed. It is used to separate particles of different density in the slurry. The product receiver is fixed on the ground to collect the separated materials discharged from the rotating jig unit. Separated materials are discharged from an outlet of the screen residue chamber in the jig unit. This invention can unselectively separate any size particles of different density in the fine slurry.Type: GrantFiled: March 14, 2011Date of Patent: August 19, 2014Assignee: Qinzhou AuraSource Technology Inc.Inventors: Chuanzhong Zhang, Hongliang Liu, Jingwu Wang

Patent number: 6915908Abstract: A method for decontaminating soil containing inorganic contaminants having a degree of liberation of at least 60%, comprising the steps of removing from a coarse fraction at least a portion of inorganic contaminants in particulate form contained therein with a jig to produce a treated coarse fraction, removing from an intermediate fraction at least a portion of inorganic contaminants in particulate form contained therein with a separator selected from the group consisting of a spiral and a classifier to produce a treated intermediate fraction, removing from a fine fraction at least a portion of inorganic contaminants in particulate form contained therein with a separator selected from the group consisting of a flotation cell and a multi-gravity separator to produce a treated fine fraction, whereby the combined treated coarse, intermediate and fine fractions are impoverished in inorganic contaminants.Type: GrantFiled: May 23, 2003Date of Patent: July 12, 2005Assignee: Institut National de la Recherche ScientifiqueInventor: Mario Bergeron

Patent number: 6612443Abstract: A centrifugal jig has a container mounted for rotation about its longitudinal axis (22), separated into an axial region (32) and a peripheral region by ragging material (41) supported by a screen (30). The peripheral region is composed of a series of hutch chambers (34) with reciprocating wall portions (45) located radially outside the screen (30), for repetitively dilating the ragging. Also disclosed is a hutch chamber construction applicable to both rotary and non-rotary jigs, having a reciprocating wall portion (45) which includes convergent wall surfaces leading to the hutch chamber concentrate outlet (44).Type: GrantFiled: August 27, 2001Date of Patent: September 2, 2003Assignee: Evans Deakin Pty LimitedInventors: Christopher George Kelsey, Ian McKenzie

Patent number: 6286686Abstract: A centrifugal jig has a container mounted for rotation about its longitudinal axis. The container is separated into an axial region and a peripheral region by ragging material supported by a screen. The peripheral region is composed of a series of hutch chambers with reciprocating wall portions located radially outside the screen, for repetitively dilating the ragging. The disclosed hutch chamber construction has a reciprocating wall portion which includes convergent wall surfaces that narrow toward the hutch chamber concentrate outlet.Type: GrantFiled: February 28, 2000Date of Patent: September 11, 2001Assignee: Lowan (Management) Pty LimitedInventors: Christopher George Kelsey, Ian McKenzie

Patent number: 3997436Abstract: Flocculated slime to be cleaned is introduced into the top of a vertically disposed, conical precipitator having at its bottom a discharge orifice. The introduced slime flows downwardly through an apertured plate mounted substantially horizontally in the precipitator. The plate is mechanically vibrated at a frequency in the range 20-100 Hz and an amplitude in the range 0.5-1.5 mm as the slime flows therethrough to liberate impurities mechanically trapped in the slime.Type: GrantFiled: June 10, 1975Date of Patent: December 14, 1976Assignee: Vish Minno-Geoloshki Institute-NisInventors: Stoycho Mitrev Stoev, Roza Tzvetanova Kintisheva
