Optimization of Cylindrical Grinding Process Parameters

2019-7-1  Abstract: Grinding is the machining processes which improve surface quality and dimensional accuracy of the work piece. Various process parameters, which affect the cylindrical grinding operation, are depth of cut, material hardness, work piece speed, grinding wheel grain size, number of passes, material removal rate and grinding wheel speed. Speed and feed are critical factors because increasing the both speed, and feed has an adverse impact on surface roughness but high material removal cause reduction in surface roughness. Cylindrical grinding is one of the important metal cutting processes used extensively in the finishing operations. Metal removal rate and surface finish are the important output responses in the production with respect to quantity and quality. In this thesis, is to arrive at the optimal grinding conditions that will minimize surface roughness and maximize metal removal rate when cylindrical grinding of EN21AMsteel is done for the optimization of grinding process parameters.

En route to multi-model scheme for clinker comminution

2021-7-14  Comminution is a very energy intensive production stepin the cement manufacturing, which involves the oper-ation of large mills to achieve a desired clinker particlesize distribution (PSD). In order to optimise this process,we focus on physical and chemical aspects of grinding.Industrial cement ball mills consist of a rotating dualchamber cylinder sized up to 8 m in diameter and 20 min length. Such mills are driven by electric motors in therange of 20–40 MW, consuming 30% of the overallelectrical energy dedicated to the entire production chainof cement.1–4Most of the earlier work on modelling ofclinker grinding was focused on the simulation of thecharge motion using the discrete element method(DEM). Until now, numerical models based on differentphysical scales present in clinker and milling systemscombining physicochemical aspects have not beenpossible to integrate into a single methodology.
