The quality of the motive steam affects the operation of the unit. The usual requirement is for dry, saturated high-pressure steam. In operation, it is very important to maintain the design quality of steam. If the quality of the steam is low, suction pressure and capacity will decrease, especially in multistage designs.

Cyclic operation may lead to failure by fatigue or loss of metal due to flaking of the oxide scale prior to the expected creep-rupture time. A discussion of the mechanical strength properties of stainless steels at elevated temperatures begins on page 5. Environment The effect of exposure of a material to media can be a very complex subject.

Vertical mill is used in grinding material at smaller particle sizes, which is used after ball mill. Pebble mill is used when product contamination by iron from steel balls must be avoided. Fluid energy or jet mill consists of a hollow toroid. A fluid, usually air, is injected as a high-pressure jet through nozzles at the bottom of the loop.

turbine - turbine - Steam turbines: A steam turbine consists of a rotor resting on bearings and enclosed in a cylindrical casing. The rotor is turned by steam impinging against attached vanes or blades on which it exerts a force in the tangential direction. Thus a steam turbine could be viewed as a complex series of windmill-like arrangements, all assembled on the same shaft.
