Dec 18, 2013 · Rotary kilns used for the conversion of enriched or depleted uranium are equipped with lifters and are externally and electrically heated, but they differ in size and nominal operating conditions, as can be seen in Table 1: the type of rotary kiln used for depleted uranium conversion is henceforth named “kiln #1”; the type of conversion kiln used for enriched uranium is named “kiln #2”
Cost-effective Rotary Kiln Production Line 30 years experience in R&D, design, production and installation of rotary kiln. Energy-saving and Environmental Protection Rotary Kiln Intelligent system, multi-stage preheater, good sealing, easy operation, low failure rate, energy saving and environmental protection
A rotary kiln is an industrial structure that processes ores by subjecting them to high temperatures (roasting) to induce a chemical change in the input material (pyroprocessing)
As shown in the drawings the vessel 1 comprises an inclined rotating barrel type kiln 2 having an inlet chamber 3 forming a first region of the vessel into which the uranium hexafluoride and dry
Uranium content is concentrated at the base of the MCB and decreases moving toward the top of the bed. The MCB ranges from 1.3 to 4.4 metres in thickness. The floater reefs are generally thinner, ranging from 0.1 to 2.0 metres in thickness, and generally contain uranium grades of less than 0.04%
Jan 01, 2000 · The 'rotary kiln UF4 plant' in- stalled converted pure uranium trioxide to uranium tetrafluoride in three stages: (i) Hydration of UO3 with acidified (nitric acid) water, a 'wetting' agent and air (this 'activates' the oxide and increases its surface area) in a conventional continuous mixer which delivers hydrated UO3 as a dry free-flowing powder to a reduction kiln
Rotary kilns are used for applications such as reduction of oxide ore, pyrolysis of hazardous waste, calcining of petroleum coke, conversion of uranium fluoride into uranium dioxide for the
Dec 26, 2019 · Rotary Kiln A rotary kiln is an inclined, rotating cylindrical reactor through which a charge moves continuously. The rotary kiln is a thermal processing furnace used for processing solid materials at extremely high temperatures in order to cause a chemical reaction or physical change
Rotary Kiln ConstructionWhile FEECO rotary kilns are custom designed around the material to be processed, in general, there are some standard components that serve as the basis of a rotary kiln. The diagram shown on the following page illustrates some of the common standard components found on a basic direct-fired kiln. A diagram of an indirect
Cement rotary kilns refer to cement rotary calcining kilns (sometimes called rotary furnaces). It is a pyroprocessing device used to heat materials to high temperatures in a continuous process. The kiln body is a cylinder vessel with a certain degree of tilt to the horizontal level

Abstract This paper deals with the mathematical modelling of a rotary kiln, which is used for the recycling of aluminium waste. This model is mainly based on the coupling between • “a bed model” describing the processes occurring within the bed of aluminium waste flowing inside the kiln, • “a kiln model” describing heat transfer within the kiln itself, • “a gas model
We claim: 1. In a process for the conversion of uranium hexafluoride to a uranium oxide which comprises injecting uranium hexafluoride and dry steam into a first region of a rotary kiln so as to form a plume of particles of uranyl fluoride in said first region, causing said particles of uranyl fluoride to be moved into a second region of the rotary kiln, and reacting the uranyl fluoride
