Clinker Coolers Introduction for cement industry

In the beginning, I offer you the simplest information about

Clinker cooling is achieved by passing air streams through the grates. Due to an oscillatory movement, the grates cause the  flow and the spreading of the solid material. The thickness of the bed depends on the speed of the grates as well as on the mass rate of clinker  in  the  kiln  outlet.  Consequently  a  heat exchange is  performed between clinker  and air.  A part of the hot air volume is introduced inside kiln as secondary  air  and  used  for  the  fuel  combustion, while the  rest is  evacuated towards the  de-dusting filter characterized as exhaust air. Efficiency of the cooler  includes  two  operations:  

(i)  The  heat recuperation from the clinker entering to the cooler,

(ii) the cooling of the clinker. A fast cooling, i.e. a low  clinker  temperature  in  the  installation  outlet, contributes to an increase of the product quality

Mechanical Elements of tubes Mills For Cement industry The course include  Introduction -  Nature of wear in ball mills -  Influence on lifetime for wear parts - A- Influence from material to be ground  B- Influence from lining thickness  C- Influence from lining shapes and surfaces  The mechanical elements of a tube mill can roughly be subdivided into internal and external parts.  The mill internals have a direct function with regard to the grinding process and include principally the wear parts of a mill such as mill liners, diaphragms and grinding media. The external parts of a standard tube mill consist of mill shell, mill heads, mill bearings, feed and discharge equipment and include also the mill drive. In the following the external parts of the tube mill are described under special consideration of the process technological aspects. The mill internals are described in separate chapters. The feed devices have to fulfill the following functions Continuous flow of material into mil

Wear Parts & Wear resistant Material in Mills   The equipment in the grinding installations therefore will have to be protected with sufficient wear resistant materials for two different reasons  In order to protec t the equipment from     damage and decay.- In order to maintain maximum output at optimum operating conditions-. Nature of Wear in Ball Mills Grinding in ball mills takes place by lifting the grinding media charge and the material to be ground followed by a return to the bottom part of the mill tube In this continuous cascading movement. The material quality of the wear parts in a ball mill must therefore partly be resistant to over hammering without cracking, and partly withstand abrasive wear.

CF Raw Meal Silo How it works  The CF (Controlled Flow) silo is a continuously operating system for homogenization and storage of cement raw meal, where the material is extracted simultaneously at different flow rates from a number of outlets in the silo bottom. The CF system, including suitable kiln feed equipment, ensures stable kiln feed composition at minimum power consumption and investment cost. The efficient performance of the CF homogenizing silo results in stable kiln operation so that changes in kiln speed or firing rate are rarely needed and stable coating in the kiln is maintained. In order to ensure high homogenization efficiency, all the raw meal in a silo must be kept in constant movement towards the outlets. Furthermore, the raw meal must pass through the silo in flow zones with different residence time. The CF silo complies with these demands. It extracts raw meal at different rates from several outlets in the silo bottom and mixes the stream from these outlets. The CF
