Particle-size analysis is often used in soil science to evaluate soil texture. Soils rarely consist entirely of one size range. Soil texture is based on different combi- nations of sand, silt, and clay separates that make up the particle-size distribution of a soil sample. The percentage distribution of those parts determines soil structure. ➢ Mechanical analysis is the determination of the size range of particles present in a soil. Sieve analysis is common practice in the forensic examination of soils in the United Kingdom where, in general, soils are sieved in a dry condition. Examination.

Particle Size Analysis (for soils/sediments) — UCL Department of Geography
Having oversize material being conveyed will cause damage to equipment and slow down production. Particle-size analysis also helps the effectiveness of SAG Mills when crushing material.
The latter cannot be separated from one another by sieving. Instead they are separated by a process known as sedimentation, which is based upon the fact that larger particles fall more quickly through water than smaller ones.
This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in. Furthermore, if the maximum particle size is greater than 4. Finally, if the maximum particle size is equal to or greater than For special conditions see The methods differ particle size analysis of soil the significant digits recorded and the size of the specimen mass required.
The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. This method must be used when performing composite sieving.

For cases of disputes, Method A is the referee method. At the base is a round pan, called the receiver. The coloumn is shaked by had usually for some fixed amount of time.
After the shaking is completed the material on each sieve is weighted. Then the weight of the sample particle size analysis of soil each sieve is divided by the total eight to give a percentage retained on each sieve.
The size of the average particles on each sieve is analyzed to get the cut point or specific size range captured on screen.
