Crushing and Grinding of Ores or Pulverisation of Ores ...

Crushing and Grinding of Ores or Pulverisation of Ores : The ores generally occur in nature in the form of huge lumps. These lumps are broken into small pieces with the help of grinders or crushers so that the chemical changes which have to take place later on may become convenient. This process is called crushing, which is done by jaw crushers.

Chromite- mineralogy and processing - ScienceDirect

Typical values of hardness and grindability are shown in Table 2 [5]. The Vickers hardness increases with the Cr203 content of chromite; grinding resistance is dependent not only on hardness, but also on the texture of the chromite. According to Owada and Harada [5] the easiest ores to grind are those containing irregularly shaped chromite ...
