Rotary Dryer And Calcination Plant The rotary dryer is a type of industrial dryer employed to reduce or minimizer the liquid moisture content of the material it is handling by bringing into direct/indirect contact with a heated gas.
Calcination is carried out in furnaces or reactors (sometimes referred to as kilns or calciners) of various designs including shaft furnaces, rotary kilns, multiple hearth furnaces, and fluidized bed reactors.

Lime rotary kiln is the main equipment of lime production line.It is widely used for many industries like metallurgy, chemical industry, building refractory materials, environmental protection, etc.Great wall lime rotary kiln has many advatages: High Automation Level, Waste Heat be Reused Effectively, Low Energy Consumption and so on.
Retention time depends on the size of the limestone as well as calcinations temperature. thus interfering with the flow of limestone in the kiln. either type of kiln can use any of these fuels. Chem. Typically. or reactivity at mild calcination temperatures of 954 to 1066°C and the bulk density remain constant. 2008). vertical kilns use oil or ...
Calcination of limestone takes places essentially at about 1000 ... Coal is also added continuously along with recycled dust from the calcination kiln that has been pelletized. The feed rate of coal is about 5% of the feed rate of upgraded ore. These materials flow slowly down the rotating kiln and out of the hot discharge end of the kiln.
The 'lime kinetic behaviour' diagram shows that heat transfer is the most important step in the calcination of raw limestone (6-25mm particles). Laboratory tests were carried out to assess different methods of enhancing heat transfer inside the kiln.
Rotary Calciner. Rotary calciners (sometimes referred to as rotary kilns) are used for a variety of material processing applications. These high temperature machines process materials into a desired form by changing the state or composition of a material, or removing moisture.
Lime Kiln is the ideal equipment to produce quicklime by the calcination of limestone (calcium carbonate).Usually, it has two types: lime rotary kiln and lime vertical kiln. These two types calcination kiln has different advantages. We will suggest you the suitable type according to the different suitations.
