ABSTRACT
This chapter examines and evaluates energy utilization inside grinding devices, grinding component processes, grinding mechanisms, and classification efficiency in relation to the physicochemical properties of the grinding environment. Possible ways to control such properties through the use of grinding aids for the purpose of improving grinding efficiency are delineated. Grinding efficiency can be defined as the amount of energy consumed per unit product of specific quality. Pulp fluidity is an important parameter in the process of transport of material and grinding media inside a mill. The state of aggregation or dispersion of the fine particles inside the mill, as well as the nature of interactions among particles and between particles and grinding media, are major factors that influence pulp fluidity. Particles in the grinding zone are normally subjected to different kinds of stresses that result in propagation and/or initiation of cracks, leading ultimately to breakage.
