An air classifier mill applies impact grinding and air clas- sification in one step. The mill uses airflow to convey feed material to the mill's grinding chamber, classifies the ma- terial into fine and coarse fractions, recirculates the coarse fraction for further grinding, and conveys fine particles out of the mill, all in one continuous ...

Power output obtained at various wind speed is plotted. Turbines are designed to work within a limited range of wind speed. The lower limit is called cut-in speed and the upper limit is called cut-out speed. In between these limits, there's a rated speed at which you can get rated output power (as shown in the graph). The wind turbine power ...

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
