Aug 24, 2015· 9 Rotary Kiln Processes: With the arrival of rotary kilns, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45% water, or they were ground dry, to form a powder or "raw meal".
Apr 07, 2020· Rotary kiln refers to rotary calcination kiln (commonly known as rotary kiln) and belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials processed.
The rotary kiln system is well suited for converting larger particle sizes and the integration of the cyclone preheater greatly improves specific energy consumption over just a straight kiln. It also reduces the size of the kiln and makes treatment of off gases very simple because the heat is removed prior to treatment.
The KVS Preheater / Rotary Kiln calcining system is selected when a uniform, high quality lime product is required. Metso can also supply vertical shaft and fluid bed types of lime calcining systems, but it is the KVS Preheater / Rotary Kiln system approach to lime calcining that is the technology of choice for the more demanding applications.

Rotary Calciners. Rotary calciners, also commonly called indirect kilns, are used in various calcination operations where exhaust gases must be minimized, when processing finely divided solids, or where temperature must be tightly controlled along the length of the kiln.. A calciner is comprised of a rotating drum inside a furnace, which is externally heated.
Harrop's first project was to design two of these tunnel kilns to fire vitrified hotel ware for the Chelsea China Company in New Cumberland, West Virginia. In 1923, Harrop designed and built the first tunnel kiln for clay brick in the U.S. for Ohio Clay Company in Cleveland.
In this chapter, we provide some of the characteristics of petroleum coke calcination process in the rotary kiln and use this as a design case study for sizing a rotary kiln for the said application.
