Crushing and Grinding of Ores or Pulverisation of Class 12
Aug 13, 2021Crushing 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.

1 crushing and grinding of the ore
Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Read More

Crushing Vs Grinding Minerallurgy
Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction.
