Wet extractive grinding process for efficient calcium

01/05/2020· Herein, the objective was to study the wet extractive grinding method to accomplish more efficient extraction of Ca from steelmaking slags. As far as authors are aware, this has not been studied before. Our hypothesis is that, by implementing the extraction and the wet grinding simultaneously, we would be able to keep the reaction surface open and reach a higher reaction rate and yield. This

Mechanical Disruption Methods: Grinding

In its various forms grinding can be used on wet, dry, and frozen samples, however it is most efficient on solid samples. One key characteristic of grinding is that friction generates heat and at times can be significant. Consequently, the heat tolerance of the analyte should be considered when selecting a grinding method. Frequently samples are frozen prior to grinding, commonly with liquid

Effect of different parameters on grinding efficiency and

The paper further demonstrates a novel method for grinding process monitoring using a neural network based on the identified grinding mechanism and relations. Fundamentals of grinding mechanism As a material removal process, grinding process is similar to other cutting processes in many respects, such as materials are removed in forms of chips (Chen, 2009; Rowe, 2009). However, grinding has
