| 20100025502 | Jet for Use in a Jet Mill Micronizer - The current invention provides an improved jet nozzle suitable for use in a micronizing jet mill or retrofitting to an existing jet mill. The improved jet nozzle incorporates a coanda effect inducing element to enhance entrainment of particles to be ground within the vortex created by the micronizing jet mill. When the jet mill uses steam to generate the jet, use of the improved nozzle will reduce energy costs by increasing the efficiency of the jet mill. | 02-04-2010 |
| 20080260627 | Methods of Controlling the Particle of Titanium Dioxide Produced by the Chloride Process - A process for manufacturing titanium dioxide by the chloride process is provided. In one embodiment, a particle size control agent comprising an ionizing agent such as potassium chloride is introduced into the reaction zone of the oxidation reactor to control the particle size of the titanium dioxide. In a first aspect, the effectiveness of the particle size control agent in controlling the particle size of the titanium dioxide is improved by adding the particle size control agent to at least one of the reactant streams at a sufficient distance upstream of the oxidization reactor to allow the ionizing agent to efficiently ionize and the particle size control agent to thoroughly admix with the stream(s) prior to entering the reaction zone. In a second aspect, the particle size control agent comprises an ionizing agent and fumed silica. In another embodiment, the amount of alumina added to the reaction zone of the oxidization reactor is increased in order to control the particle size of the titanium dioxide. | 10-23-2008 |
| 20080219087 | Fluid Mixing Apparatus and Method - Methods and apparatus are provided for influencing mixing of a first fluid injected through a slot into a second fluid flowing through a conduit, by automatically or remotely adjusting the slot width to provide at least a certain slot velocity of the first fluid being introduced into the conduit. In particular, methods and apparatus are provided for mixing control in injecting titanium tetrachloride into an oxygen stream in a process for making titanium dioxide. | 09-11-2008 |
