Hydraulic circuits

Hydraulic circuit comprises of various components such as electric motor which converts electric energy into mechanical energy and the pump converts mechanical energy into hydraulic energy and the actuator converts back hydraulic energy into mechanical energy. Control elements like valves are used which controls the fluid in the circuit such as direction control valves, flow control valves & pressure relief valves etc.
- Regardless of its function and design, every hydraulic system has a minimum number of basic components in addition to a means through which the fluid is transmitted. A basic system consists of a pump, reservoir, directional valve, check valve, pressure relieve valve, selector valve, actuator, and filter.

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
