They are classified as jaw, gyratory and cone crushers based on compression, cutter mill based on shear and hammer ...
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 ...
Mineral Comminution and Separation Systems
consist of size reduction (or comminution) by crushing and grinding for the liberation of minerals, separation of mineral particles by va rious principles and a number of operations associated with them. However, most of the processes are basically physical (or mechanical), even if chemical effects may play important roles.
