sand particles range in diameter from 0.0625 mm (or 1⁄16 mm) to 2 mm. An individual particle in this range size is termed a sand grain. Sand grains are between gravel (with particles ranging from 2 mm up to 64 mm) and silt (particles smaller than 0.0625 mm down to 0.004 mm). The size specification between sand and

Medium-coarse sand is generally used for concrete and mortar. Sand specifications are divided into three types: coarse, medium and fine according to the fineness modulus (the index that characterizes the thickness and type of natural sand particle size). Fine sand: The fineness template is 2.2~1.6, and the average particle size is 0.35~0.25mm.

Another common cause for your truck to emit a vibration is a worn-out tie-rod. One way to tell is to lock your wheel to one side and inspect the rubber boots underneath. If they are torn or perished with traces of oil seeping out, then you most likely have a worn-out tie-rod end. Another way to inspect is to jack up the vehicle and shake the wheel.
