The material is passed through sieves of progressively finer mesh and each fraction is weighed.
(a sieve is a net , grid or parallel arrangement of wires/plates that lets particles of dimension finer than the mesh size pass while sorting coarser particles into a dedicated container.
What else can I help you with?
Under what conditions should you use wet sieving instead of dry sieving?
Wet sieving is typically used when the sample material is cohesive, contains fines, or when the particles are highly irregular in shape. It helps to overcome issues such as agglomeration, particle trapping, or size underestimation that can occur in dry sieving. Wet sieving is also useful when accurate particle size distribution data is needed for fine-grained materials.
When particle size of constituents are different to separate the component we use?
The most simple method is sieving.
Is sieving is most useful?
Sieving is a useful technique for separating mixtures based on particle size. It is commonly used in industries such as agriculture, food processing, and construction. Sieving helps to remove unwanted particles and ensure product uniformity.
What is sieving used for in school?
Sieving is used in school primarily as a method to separate solid materials based on their size. It helps students understand concepts related to particle size and mixtures, often in science experiments involving soil, sand, or other granular substances. Additionally, sieving can be a practical illustration of mathematical concepts like measurements and ratios, enhancing hands-on learning experiences.
How can you use particle size to separate a mixture?
Particle size can be used in techniques like filtration and sieving to separate mixtures. Larger particles are retained while smaller particles pass through, resulting in separation based on size differences. This is commonly used in industries like mining and agriculture to extract desired components from a mixture.

Which graph best represents the range of particle size that can be carried by a glacier?
A graph showing particle size (y-axis) versus distance from glacier source (x-axis) would best represent the range of particle sizes that can be carried by a glacier. The graph would show that larger particles are carried closer to the source of the glacier, while smaller particles are transported further away.
What is difference between winnowing and sieving?
winnowing is the separation of solid-solid separated by size and weight whereas sieving is the separation solid-liquid judged by shape and size.
What difference in properties allows substances to be separated by sieving?
Sieving separates substances based on differences in particle size. Materials with larger particles are retained on the sieve, while smaller particles pass through the openings. This method is effective for mixtures where the size of the components varies significantly, allowing for efficient separation without altering the chemical properties of the substances involved.
How do you measure particle size in soil?
Particle size in soil is typically measured using sieving, which separates particles by size using a series of mesh screens. Other methods include laser diffraction or sedimentation, which analyze the scattering of light or settling rate of particles in a liquid medium to determine particle size distribution. Each method has its advantages and limitations, so the choice of method depends on the specific characteristics of the soil being analyzed.
Is sieving sand from stones reversible?
Sieving sand from stones is a physical process that separates the two based on their size differences. This process is reversible because the sand and stones can be easily separated again by using the same sieving method. By passing the mixture through a sieve, the smaller particles (sand) will fall through the sieve while the larger particles (stones) will be left behind, allowing for the separation to be reversed.
