Computer Simulation For The Milling Process Of Cement

So as to design the pavement planer, it is necessary to study the milling performance of cement concrete. In this work, a coupled thermo-mechanical plane-strain large deformation milling finite element simulation is presented to analyze the cement concrete milling process and predict the stress and temperature field. A model for actual cutter and milling cylinder is set up.

The Cement Kiln

The milling process generates heat and excessive mill temperatures are undesirable. It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials.
