An application example is the fluid coking process, in which a steam flow is injected in order to destroy agglomerates [6]. Moreover, injecting high speed jets can be used for autogenous fine grinding in spiral or opposed jet mills [7,8]. Inside these mills, the injected gas is loaded with particles developing a multiphase jet.

However, the confined vortextype fluid energy mill is a rather complex fluidic device. It involves particle interactions with highvelocity gas molecules and the fluid dynamics is further complicated by solid feeding and discharging. Performance of confined vortextype fluid energy mills can differ greatly for a small change in the design of mill.

During the 1930s, Sturtevant introduced an ultrafine grinder, the Micronizer®. This fluid energy mill opened up many new and promising markets. The same decade saw the development of two more pulverizers which were intermediate to the older crushers and the Micronizer®, representing a relatively new concept of fine grinding by impact.
