Exploring Wind Energy. Heat from the sun causes convection in the atmosphere, meaning the heated air rises. These currents create zones of high and low air pressure within the atmosphere. As the heated air rises, it creates a low pressure zone near the ground. Air from surrounding cooler areas rushes in to balance the pressure.
Fluid energy mill is also known as jet mill. It works on the principle of impact and interparticle attrition to achieve the desired particle size.
Principle of fluid energy mill. It is based on the effect and attrition idea. The inlet and exits are connected by a classifier, which stops particles from passing until they are fine enough, as shown in Fig. 2.5. (a). It aids in the size and shapes determination of particles. The efficiency of air/inert gas is directly proportional to its speed.
