Bond's Law: The work required to form particles from very large feed is proportional to the square root of the surface-to-volume ratio. E = K B f c [(1/L 2 ) 1/2 - (1/L 1 ) 1/2 ] Rittinger's Law — The energy required for reduction in particle size of a solid is directly proportional to the increase in surface area.

The primarily used equipment in crushing are-jaw 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.

2016/1/1During manual crushing and disintegration of a rock with a hammer, or during mechanical crushing operations, the size reduction of large sized rocks and ores is mostly by sharp impact action, and less so by the impact and attrition experienced in tumbling mills.

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material
