Fineness Modulus of grading of aggregate. Fineness modulus is an empirical factor computed from the sieve analysis. It is defined as the sum of the cumulative percentages retained on the sieves of the standard series ranging from 80mm to 150microns and dividing the sum by 100. When all particles in a sample are coarser then say 600µm, the ...

Vibrating sieves from Rotajet can be configured to separate as many as 5 product fractions in one operation by stacking multiple screening deck systems on top of one another. By optimising the vibratory action and time spent on the screening area, these separatory machines offer the most acute grading down to 200 micron.

A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

Sieve analysis equipment is used to characterize and classify sand, aggregate, soils, coal, grains, and many types of fine powders. With our large inventory and wide range of ASTM (American Society for Testing and Materials) and ISO (International Organization for Standardization) Test Sieves, Gilson is the best source for your sieves and particle size analysis equipment.

Most sieves are available in commercial or precision grades. All federal grain inspectors use precision sieves, but for most appliions the commercial sieves will suffice. Sieves should be replaced when the perforations show wear, to maintain accurate results.

Grade of powder Sieve through which all particles must pass Coarse 10 Moderately coarse 22 Moderately fine 44 Fine 85 Very fine 120 . The BP specifies a second, smaller size of sieve for the coarser powders but states the not more than 40 per cent shall pass through. The ...

The air jet sieve is a sieving machine for single sieving, for each sieving process only one sieve is used. The sieve itself is not moved during the process. The material on the sieve is moved by a rotating jet of air: A vacuum cleaner which is connected to the sieving machine generates a vacuum inside the sieving chamber and sucks in fresh air through a rotating slit nozzle.

 · Generally sieves are constructed of brass and stainless steel components, common diameters are 3 inches, 8 inches and 12 inches or metric equivalents, special diameters are also available tests sieves are available in three grades: compliance,inspection and calibration. compliant grade tests sieves are primarily used.

1. Oscillating Sieve type Oscillating sieve precleaners are simple and often made locally. The machine consists of two sieves of different sizes depending on the size and shape of the grain. The top sieve has a slotted profile larger than the bottom and both screens can be changed to .

There are also fixed machines, rolling sieving machines and movement sieving machines. Speak to our team if you're not sure which type of sieving action is suitable for your company. If a sieving machine is not quite right for your purposes then you might want to look at the other products that we have available, including vibratory separators and grinding mills .
