Mill (grinding)

Mill (grinding)

A grinding mill is a tool that is designed to break a solid material into smaller pieces. There are many different types of grinding mills and many types of materials processed in them. Small mills can be powered by hand, such as a mortar and pestle or a pepper grinder. Large grinding mills were usually powered by working animals, wind or water in the past.

How Do Wind Turbines Work? | Department of Energy

How Do Wind Turbines Work? | Department of Energy

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

Jet mill working principle

Jet mill working principle

Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heatsensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy.
