Rotary Kiln
CIC’s equipment includes leading standardized heavy equipment and machinery products and related heavy machinery services, which can be sold directly to end customers, business partners, and EPC projects. As a professional heavy equipment companies, CIC serves multiple roles, such as, cement machinery suppliers, mining machinery manufacturers, grinding mill manufacturer, rotary kiln manufacturer, rotary dryer manufacturer, sludge dryer manufacturer and so on.
Since 1950s, CIC had started the manufacturing of pyro processing equipment. These series of pyro processing equipment were used in various field, that enforce us to overcome many difficulties. Nowadays, our products meet the incineration requirements of this equipment for various materials. The complete sets of the pyro processing equipment CIC can provide includes the dry, semi-dry and wet-processed rotary lime kiln, kiln thrust roller, self-return soda steam calciner, rotary kiln in cement industry, environmental dryer and cooler, and etc which are widely used in the industries of cement producing, metallurgy, chemical, environment protecting and so on/,etc.
Design of Rotary Kiln
lShell: Kilned carbon steel and alloy steel shell by automatic welding.
lSupporting Device: Advanced spindle with automatic temperature measuring device and electronic heater unit.
lTyre and Roller: Made of ZG35CrMo steel and 42CrMo steel.
lDriving Device: Equipped with the reducer with the hard tooth surface and flexible diaphragm coupling, by continuous current dynamo or variable-frequency and variable-speed motor.
lKiln Seal Device: Different types of the incineration furnaceare designed to match the needs.
lLow-speed driving device is equipped.
What are the Design Parameters of Rotary Kiln?
lRaw material
lInlet and outlet temperature
lSize of rotary kiln for cement manufacture
lProcessing capacity
lScope of supply
How to Stabilize Kiln Temperature in Summer and Keep the Production?
lThe heat transfer modes of high-temperature gas in a rotating kilnto kiln skin are radiation heat transfer and convection heat transfer;
lThere is only conduction heat transfer among kiln skin, kiln brick and kiln shell;
lThere is only convective heat transfer between the outer wall of the activated carbon kiln/activated carbon rotary kilnand the surrounding environment;
lThe kiln skin is in close contact with the refractory brick, that is, the temperature of the kiln skin at the contact position is the same as that of the brick;
lThe firebrick is in close contact with the kiln body, that is, the temperature of the firebrick at the contact part is the same as that of the kiln body;
lThe inner surface temperature of the kiln is the same as the outer surface temperature (the thickness of the kiln is ignored).
