Manual Size Reduction Methods
Pulverization Trituration. Trituration is a manual method of size reduction where the particle size of solid substances is reduced by grinding, rubbing or striking in a mortar with the help of a pestle. The process of trituration is also known as dry grinding as no liquid aid is used for size reduction by using the trituration process.
The action of reducing a material to small particles is:
