Particle size, also called grain size, means the diameter of individual grains of sediment, or the lithified particles in clastic rocks.The term may also be used for other granular materials.
Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness

Fine aggregate or sand has only one range of particle sizes for general construction and highway work. The grading and grading limits are usually expressed as the percentage of material passing each sieve. Fig. 56 shows these limits for fine aggregate and for one size of coarse aggregate. There are several reasons for specifying grading limits

Combinations of sand and crusher fines mix Various fractions of crusher fines were added to the original sand samples in various percentages and optimized sand samples were than tested for the improved gradation and improved fineness modulus. These improved versions of results were then compared with the ASTM specified limits.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
