with decreasing grain size Machinability is also affected rough machining favors coarse grain size while finish machining favors fine grain size The effect of grain size is greatest on properties that are related to the early stages of deforma-tion Thus, for example, yield stress is more dependent on grain size than ten-sile strength 2, 3...

Sand is a mixture of small grains of rock and granular materials which is mainly defined by size, being finer than gravel and coarser than silt And ranging in size from 006 mm to 2 mmParticles which are larger than 00078125 mm but smaller than 00625 mm are termed silt Sand is made by erosion or broken pebbles and weathering of rocks, which is carried by seas or rivers...

The sand is freed from clay and organic impurities by log washers or rotary scrubbers After scrubbing, the sand typically is sized by water classification Wet and dry screening is rarely used to size the sand After classification, the sand is dewatered using screws, separatory cones, or...
