1. Introduction. Emulsion explosives (EE) are one of the most recently developed classes of energetic materials [1,2,3,4,5] and can be perceived as a step forward from the traditional energetic materials based on ammonium nitrate (AN), such as amatols, ammonals and ANFO (ammonium nitrate-fuel oil).EEs are obtained by physically or …
ABSTRACT Many years of research on more effective and safer explosives led to the development of emulsion explosives. They are the second most commonly used group of explosives in the world, primarily due to the fact that they are a good alternative to ANFO explosives or dynamites. Their key advantage in underground applications is the …

Colloid mills are rotor-stator mixers that are commonly used to make emulsions and dispersions. It can also be used to make solids in suspension smaller. A high-speed rotor inside the colloid mill forces the fluid through small holes in a stationary stator, resulting in significant mechanical shear. The user can manage the level of shear …
Construction of the Colloid mill. The construction of a colloid mill is shown in Figure 1.1. The mill consists of a high-speed rotor and stator with a conical milling surface. The milling surfaces may be smooth-surfaced or rough-surfaced. Rough surfaced mills are used for fibrous material because fibers tend to interlock and clog smooth ...
