2. Intermediate crushing or secondary crushing: The feed material is usually product of a jaw crusher. 3. Fine crushing or coarse grinding: The feed material is usually comes from the secondary crushers. 4. Fine Grinding: The objective of fine grinding is to produce ultrafine material less than one micron.

The research of crushing theory is mainly summarized as the following three major aspects: the study of strength theory, the research of crushing effect, and the research of crushing power consumption. Based on the principle of more crushing and less grinding, a new crusher developed based on the principle of material layer crushing is the ...
pigments for inks and paints, but are quite energy inefficient. The crushing mechanism is a combination of impact with the grinding media and shearing between the media and the cylinder walls as seen in figure 1. A variation is a jar mill, in which relatively small ceramic containers holding some grinding media are rotated on a common machine ...
Theory of Comminution Comminution theory is concerned with the relationship between energy input and the particle size made from a given feed size. The greatest problem is that the machine itself absorbs most of the energy input to a crushing or grinding machine, and only a small fraction of the total energy is available for breaking the material.
grinding. Most particularly, energy consumption in grinding is large. The reason is that the change from feed size to product size, achieved in grinding, is typically much greater than in crushing. There is significant evidence that blasting does affect crushing and grinding results, and that
When crushing and grinding, a lot of mechanical energy is consumed, and therefore it is important to choose the grinding media correctly. In most cases, a combined effect of grinding forces occurs, for example crushing with abrasion, impact with crushing and abrasion; sometimes side-bending and tearing join the main effort.

Bond and Wang theory. [ ¦bänd ən ′waŋ ‚thē·ə·rē] (mechanical engineering) A theory of crushing and grinding from which the energy, in horsepower-hours, required to crush a short ton of material is derived.
The Rittinger theory is the older and more widely accepted. In its first form, as stated by P. R. Rittinger, it postulates that the useful work done in crushing and grinding is directly proportional to the new surface area produced and hence inversely proportional to the product diameter.
Bond(1951) proposed a third theory of comminution which is still widely used today. King and Shcneider(1995) at the University of Utah have very recently demonstrated improved modeling of grinding circuits. Overall blast optimization has more recent roots. MacKenzie(1966) reported on costs in iron ore from drilling through crushing.
