crushing of minerals sands:

Mineral processing Wikipedia

4/3/2005· 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.

Characterization of Fines Produced by Sand Crushing

12/12/2007· Sand particle crushing generates coarse fragments with size d ⩾ 75 μ m and fine fragments, i.e., “fines,” with size d < 75 μ m.Yet, postcrushing fines are seldom characterized due to testing constraints. An experimental study was conducted to examine the size distribution evolution of fine fragments generated by crushing two uniform sands with contrasting degrees of mineral composition
