how to sense the coal particle size while crushing st

Fundamentals of Mechanical Engineering - EIT

3.2.2 Strengthening by grain size reduction. Mechanical properties of materials depend on arrangement of grains, their shapes and in particular, their size. Grain size directly controls the extent of slip interference by adjacent grains and affects the properties of strength, toughness, ductility and fatigue of metals.

Cast silicon: Crystalline silicon obtained by pouring pure molten silicon into a vertical mold and adjusting the temperature gradient along the mold volume during cooling to obtain slow, vertically advancing crystallization of the silicon. The polycrystalline ingot thus formed is composed of large, relatively parallel, interlocking crystals.

The size of the bud depends on where it is located on the plant. Larger artichokes are found on central stems towards the top of the plant, where they receive maximum sunshine. Smaller or "baby" artichokes are found lower down on the plant where they are shaded from the sun by the larger buds above.
