Sieves are common laboratory requirement. Sieves are used for sieving of chemical powders, medical powders, aggregate, sand soil cement. These sieves are manufactured as per various standards like ISS, BSS, ASTM, DIN Civil Engineering it is a common practice to use sieves for gradation and particle size
NO. 530 Sand Testing Sieves: A nest of 11 AFS sand testing sieves for determining the AFS Grain Fineness Number and distribution of molding and core sands. Included are sieves No. 6, 12, 20, 30, 40, 50, 70, 100, 140, 200 and 270. Pan and cover provided. Sieves are stacked in order of meshes and test sample placed in top sieve.
The sieving action is provided by an offset weight motor which imparts a random multidirectional motion to the sieve stack. This action provides an ideal movement for particle sizes up to 20mm. A timer is fitted to provide automatic stop on completion of test. SIEVE CAPACITIES ( for standard FullHeight Sieves) 10 Sieves of 200 mm / 8 inches size
For example, if the particle size of a material is described as 4 +40 mesh, then 90% or more of the material will pass through a 4mesh sieve (particles smaller than mm) and be retained by a 40mesh sieve (particles larger than mm). If a material is described as 40 mesh, then 90% or more of the material will pass through a 40mesh ...

Raise the soil container over the nest of sieves and while holding the mousedown click the ctrl button to pour the soil into the sieves. Then mount the sieves into the sieve shaker.
The Air Jet system is suitable for sieving powder and dry grain products, obtaining sieving results between 5 to 4000 microns. A vacuum machine applies a controlled decrease of pressure to the chamber beneath the sieve, drawing air out of the sieve through the apertures and carrying with it any particles smaller than the sieve aperture size.
Sieve Aperture size mm Table 2 : Sieves required for mortar testing Figure 1 : A nest of sieves The test sample is placed in the top sieve of the nest and the sieves are agitated until material ceases to pass each of the sieves, the mass of material retained on each sieve is then determined.
Sand Grain Size Analysis Materials Needed Equipment: (per table) 1. 6 sets of sieves = 10, 18, 35, 60, 120, 230, pan (6 sieves and the pan) 2. Electronic Balances to measure mass of samples
A specially built Image Analyzer is used for consistent accuracy, sieve after sieve. All Test Sieves are made in accordance with specifications established by ASTM E11. Test Sieve Frames Sieve frames are die formed for guaranteed fit and superior quality. All test sieves .

Sieve size Rounded Irregular Crushed 40 mm 20 mm 10 mm mm Fine Flaky aggregate are the aggregates whose least dimension is less than 3/5th of its mean dimension the mean dimension of an aggregate passing through 40 mm sieve and retained on 20 mm sieve is 40+20/2 = 30 mm. Now if the least dimension is less than18 mm

Sieves are selected to cover the entire range of particle sizes present in the test nest of sieves is completed by a wellfitting collecting pan at its base and lid at its micrometers or millimeters in denoting test sieve openings. [NOTE— Mesh numbers are provided in the table for conversion purposes only.
These sieves are excellent for determining the particle size of sand. It is ideal for checking topdressing sands, measuring the consistency of sand trap sands and a must for use during construction. The Brass Sieve Set comes with a full USGA breakdown with six, eight inch diameter sieves that form a stack with the below diameter mesh screens.
