Patent number: 5628563Abstract: A method and apparatus for supplying gypsum slurry of predetermined concentration to a follow-on utilization device, such as an irrigation network. Slurry of a first higher concentration is prepared in a vessel using a vertically arranged mixer with power and drive components mounted outside the tank and a mixer shaft bearing an impeller and a propeller positioned inside the tank for immersion in the slurry ingredients. Rotation of the impeller and propeller causes the slurry ingredients to flow downwardly in the central region of the vessel, outwardly near the bottom towards the inner wall surfaces, upwardly of the inner wall surfaces towards the top and inwardly to the central region in a cyclic fashion to produce a uniform slurry. The slurry is withdrawn through an outlet in one of the tank walls and mixed with externally supplied water in a mixing chamber to dilute the slurry to a desired useable concentration.Type: GrantFiled: November 3, 1995Date of Patent: May 13, 1997Assignee: Montague/Fisher, Inc.Inventor: Donald S.

Patent number: 5624186Abstract: A method and apparatus for mixing two or more materials which are difficult to mix. The dispersion apparatus has a cylindrical housing which is divided into an upper chamber and a lower chamber by a baffle. The materials to be mixed are forced under high pressure into the lower chamber which is divided into three pressure zones by kinetic baffles. A turbine blade imparts energy to the liquids which are kept from swirling by the kinetic baffles. The high pressure of the materials introduced into the chamber forces the materials through an opening between the baffle and shaft turning the blade into the upper chamber. In the upper chamber a second blade imparts centrifugal force to the materials to force them outwardly through a porous screen. The materials are sheared as they move through the screen and then are delivered to an outlet.Type: GrantFiled: February 6, 1996Date of Patent: April 29, 1997Assignee: Chem Financial, Inc.Inventor: Ray Ogier
