Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
Biobased circular materials are alternatives to fossil-based engineering plastics, but simple and material-efficient synthetic routes are needed for industrial scalability. Here, a series of lignin-based vitrimers built on dynamic acetal covalent networks with a gel content exceeding 95% were successfully prepared in a one-pot, thermally activated, and catalyst-free …

Key words: Finite element method, grinding, simulation 1 INTRODUCTION The modelling and simulation of a grinding process are generally based on the relationship between the process parameters and results in grinding. Finite Element Method (FEM) is the most frequently used numerical methods in metal cutting processes (Wu et al. 2005).
The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw ...

Introduction. Glycyrrhizin, an oleanane-type triterpenoid saponin, is obtained from the dried roots (stolons) of Glycyrrhiza species (G. uralensis, G. glabra and G. inflate) which is widely recognised as a natural sweetener, flavouring agent and crude drug in Japanese, Chinese and Indian systems of medicine (Shibata et al. 2003).

The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.
Grinding is always the final procedure in the manufacturing process, which will decide the final characteristic of surface layer and its surface integrity of the workpiece.
Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can
Petroleum sludge is a waste product resulting from petroleum industries and it is a major source of environmental pollution. Therefore, developing strategies aimed at reducing its environmental impact and enhance cleaner production are crucial for environmental mortar.

1 Introduction. Mitigating the environmental consequences of anthropogenic CO 2 emissions is one of the major challenges of this century. For every ton of cement that is produced, one ton of greenhouse gases is released into the atmosphere, and the production of Portland cement accounts for ≈8% of anthropogenic CO 2 release. [] Portland cements contain …
