Recent work using high-speed photography revealed that low-pressure flood coolant was easily deflected by the air barrier, especially when the nozzle jet was aimed directly into the "V" of the grinding zone. The air was shown to remain with the wheel and enter the grinding zone, and the coolant was reflected back.

The surrounding air pressure outside of the vacuum forces the air up through the hose and into the vacuum. The dirt and debris that gets sucked up with the air passing through a filter which captures those particles – allowing for clean air to be released. WHAT IS CFM? CFM stands for Cubic Feet (of air) per Minute.

Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012). Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used.

The air pushes the piston for the grinding stroke. At the end of the grinding stroke air from the solenoid valve reaches the rear end of the cylinder block. The pressure remains the same but the area is less due to the presence of piston rod. This exerts greater pressure on the piston, pushing it at a faster rate thus enabling faster return stroke.

Prater's Air Classifying Mills operates by using the combination of two-stage closed circuit grinding/milling with an interstage air classifier all in one convenient unit. The internal air classifier continuously recirculates particles that are larger than desired back into the grinding zone ensuring an optimal final product particle size.
