A sieve is considered overloaded when the mass of the material retained on a sieve exceeds the maximum allowed as follows: 1. For sieves with openings 4.75 μm (No. 4) and larger, the mass in kilograms shall not exceed the product of 2.5 x sieve opening in millimeters x effective area of sieving surface in square meters (the mass in
the sieve openings by gently working from either or both sides with a trowel or piece of flat metal until the aggregate is freed. Banging the sieve on the floor or hitting the sieve with a hammer will damage the sieve. The final total of the weights retained on each sieve should be within 0.3% of the original weight of the sample prior to grading.

Sieving is a method of using a sieve to distinguish small particles from bigger particles. It is used in flour mills or building sites. Impurities such as husks and stones are extracted from wheat at flour mill. They remove pebbles and stones from sand through sieving.

The sand is commonly known as the basic material use in construction side or any other product. Comes with few type and different size comes in mixture. Sieve machine: i. To design sieve machine that can sieve sand to different size. ii. Problem that often faced is that some product required different size of sand to fulfill the quality level ...
weight is the weight of the sand from -1 added to the 0 phi weight of sand. So 2.95 + 4.95 = 7.90, and the 1 phi cumulative weight is 7.90 + 13.36 = 21.26, etc. Weight percent is the total weight of Sieve Fraction Divided into each weight of the sand fractions. Thus for -1 phi 2.95 is divided by 33.42 then times 100 = 8.83 %.
3. Sieve shaker: Any mechanical sieve-shaking device that accomplishes the same thoroughness of sieving as the hand-sieving procedure described in F.1.a of this method. a. It is essential that the sieve shaker be designed so that its motion includes a bumping or bouncing action sufficient to keep the aggregate particles in

2) Mechanical sieve shaker -- appropriate model to accommodate sieves. 3) Sieve brushes -- Wire and bristle brushes (a wire brush will damage a No. 50 or smaller sieve). Decantation Equipment required for AASHTO T 11: 1) Sieves - No. 16 and No. 200. The No. 200 sieve can be protected from punctures and tears by covering with a No. 16 sieve.
Sand Sieving Mesh: A sand sieve mesh has been designed by using clamps and a square block which is welded, and fixed to the clamps that hold the thin sheet of mesh rigidly. The standard dimensions of the mesh are 300*50*2 mm. Fig.3.2. Sand Sieving Mesh DC Motor and Gear Arrangement: This is an arrangement of gear box used in the sieving machine.
Sieving of sand is carried out using rectangular mesh which is inclined at certain angle. This causes a relative motion between the particles and the sieve. Depending on their size the individual particles either pass through the sieve mesh or retained on the sieve surface. There are different machines that are being used for sand sieving ...

Sieving is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one-another and screen openings. Depending upon the types of particles to be separated, sieves with different types of holes are used.

wheat is poured on a slanting sieve. The sieving removes pieces of stones, stalk and husk that may still remain with wheat after threshing and winnowing. to separate pebbles and stones from sand (Fig. 5.7). Activity 4 Bring a sieve and a small quantity of flour from home, to the class. Sieve the flour to separate any impurities in it.

sieve and predominantly retained on the 75 µm (No. 200) sieve is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate." Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.).
