TECHNICAL NOTES 8 GRINDING R. P. King
The grinding action is induced by relative motion between the particles of media the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition. In autogenous grinding machines fracture of the media

Crushing in Mineral Processing
In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wearresistant plate/surface.

VIBRADRUM® Grinding Mill & Crushing Mill General Kinematics
There are no dead zones of inactive media inside the vibrating grinding mill. And, unlike stirred or tower grinding mills which grind by attrition, the VIBRADRUM® Grinding Mill uses the principle of impact grinding which causes clean breaking and does not coat the mineral/gangue with slimes.

Mineral processing Wikipedia
The primarily used equipment in crushing arejaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy

Metallurgy & Mineral Processing
1 Over the past 15 years, minetomill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.

Fine grinding: How mill type affects particle shape
Circles represent grinding beads, shaded and notshaded represent different mineral phases. A mineral grain is defined as a 3dimensional entity consisting of only one mineral phase: particles consisting of one, two, or more grains are defined as liberated, binary and composite particles respectively.
