A new population balance model for ball mill is proposed. • The piston flow process has been introduced as a more realistic process. • The parameters of the model have been determined for tungsten ore. • The evolution of the particle size along the mill been studied. • The relationship between the PSD and the position inside the mill is established.

Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be 21-24 % of the empty mill. Now, in order to get an efficient milling action, 80-110 % of the pores in the ball bed must be filled with the actual particles to be ground.

With the need to process low-grade finely dispersed ores the development of ultrafine milling processes has increased apace in recent decades (Lichter and Davey, 2002) and the rapid increase in power requirements and decrease in milling efficiency is well documented.

Size reduction in impact crushers occurs through particle concussion by rigid forces. The hammer crusher , also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device .

In this chapter, the fundamental aspects are emphasized rather than mechanical or process engineering aspects, to form a background for intelligent decisionmaking in the choice and analysis of size reduction systems.

process, is to obtain mathematical relations between the size of the feed and the size of the product. Particles in the feed repetitively reduce their size due to the imparting energy of the grinding media which disrupts their binding forces. The size reduction is a result of the following three basic fragmentation mechanisms [25, 46].
