A Mechanical Shaker for Sieving Dry Soil Samples
sieving is used to determine the proportion of stable aggregates resistant to water disruption during rainfall [6], dry sieving is utilized mainly to relate particle sizes to soil erosion by wind [1]. Determining particle size distribution of a soil by hand is a very tedious process, hence, the use of mechanical shakers which makes the process a much simpler one. From a search of literature

Determine Particle Size Distribution of Soil by Sieving
The material retained on different sieves is determined. The percentage of material retained on any sieve is given by Where = mass of soil retained on sieve ‘n’ M= total mass of the sample. The cumulative percentage of the material retained. Where P 1, P 2 etc are the percentages retained on sieve 1, 2 etc which are coarser than sieve ‘n’.
Sieving Factors in Sieving and Sieving Method VEDANTU
There are two types of sieving, dry sieving and wet sieving, which can be done mechanically or manually, depending on the amount and size of particles to be separated. Dry sieving is the recommended method for particle size ranges from 40 µm to 125 mm. If dry sieving does not allow for an acceptable separation of individual fractions, wet sieving is recommended for

Fineness Modulus of Cement by Dry Sieving The Constructor
Calculation. Ravg = (R 1 +R 2 +R 3) / 3 Fineness modulus of cement = Ravg / 100 Importance of Cement Fineness. The fineness of cement affects hydration rate, and in turn, the strength. Increasing fineness causes an increased rate of hydration, high strength, and high heat generation. Bleeding can be reduced by increasing fineness.
