Abstract
Usually the axial thrust of a rotary kiln has been controlled by a hydraulic thrust device that constantly pushes the kiln up against gravity. However, the life of the device will be deteriorating earlier expected if other mechanisms are ignored to consider incorporating so that magnitude of the thrust is shared with because the thrust load varies for different factors to extreme values that could damage different components of rotary kiln system including the hydraulic thrust. Using static and dynamic modeling together with ANSYS and CATIA software it is possible to show the effects of speed and skewing angle in controlling the axial thrust of rotary kiln. And this will help for the development of technology which will further be assisted by automation by considering the different varying factors of operating conditions that include mainly the surface condition of support rollers, slope of the kiln, rotational speed of the kiln, capacity of the rotary kiln, stability of the support roller alignment, roller lubrication, proper functioning of the hydraulic thrust device and others. After going through all these variables it is easy to come up with a particular setup that guides the operator/maintenance crew to maintain the specific condition to help moderate the axial thrust of the rotary kiln. Because of time and resource limitation this thesis is mainly concerned with the effect of rotational speed and skewing angle of a kiln which are the major factors affecting axial thrust and it will use analysis method of mathematical and ANSYS modeling. And with this we can prolong the lives of different components, increase production uptime, and reduce power consumption
