Crushing Vs Grinding - Minerallurgy

Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling. Additionally, some chemical reagents can be used to minimize the energy consumption of grinding, because grinding energy is minimum at pH of the point of zero electrical charges of the ...

Energy and temperature analysis in grinding

2014-5-17  Grinding is a very efficient process for machining hard materials and has the potential to achieve high accuracy of shape and size. Conversely, abusive machining can lead to a range of forms of surface damage. Generally, it is found that the higher is the machining temperature, the greater is the damage caused to the workpiece. ...
