Grain that is not processed well enough results in slow or incomplete digestion and low feed efficiency. Grain particle size can be measured accurately and precisely by utilizing the method descrived in ASAE S319.4, which includes Ro-Tap shaking through a set of 14 sieves with various sized apetures.
ASTM Test Sieves come in several diameters: 3in (76mm), 6in (152mm), 8in (203mm), 10in (254mm), 12in (305mm) and 18in (457mm) and full or half height frames with different sieve sizes for a wide range of particle sizes. 12in Sieves also have an option for an Intermediate Height Frame. Selection of frame diameter and height is based on specimen ...
Larger sieve openings (1 in. to 1/4 in.) have been designated by a sieve "mesh" size that corresponds to the size of the opening in inches. Smaller sieve "mesh" sizes of 3 1/2 to 400 are designated by the number of openings per linear inch in the sieve. The following convention is used to characterize particle size by mesh designation:
through the finest sieve. Skirt: section of test sieve below the sieve mesh that allows for mating or nesting of the sieves in a test stack. Support mesh: coarse sieve cloth mounted under fine sieve cloth in a test sieve to provide extra strength. This is widely used in wet sieving operations to protect the fragile fine sieve cloth.
Particle size passing the sieves: The notation Dxx refers to the size D, in mm, for which xx percent of the sample by weight passes a sieve mesh with an opening equal to D.The D10 size, sometimes called the effective grain size, is the grain diameter for which 10% of the sample (by weight) is finer.
normally used are the standard 8 inch (200 mm) sieves. With Fine Aggregate the coarse sieve or the 3/8" (9.5 mm) sieve at the top; each sieve below is ﬁner; and the ﬁnest sieve, a No. 200 (75 µm) is at the bottom. A pan is placed below to retain any ﬁne material that may pass this sieve.

METHOD OF TEST FOR SIEVE ANALYSIS OF FINE AND COARSE AGGREGATES A. SCOPE This method, which includes modifications of AASHTO Designations T 11, T 27, T 30, and T 37, specifies the procedures for determining the particle-size distribution of fine and coarse aggregates.
Defining Particle Size Introduction: Particle size (PS) is an important consideration for many applications of chemical salts. Particle size distribution (PSD) is also regarded as a critical parameter in some applications where either the fines or the coarse material may impede the results that the customer is trying to achieve.
A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil 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 ...

Because extremely fine particles have a tendency to agglomerate and therefore often clog up the sieve, the air jet sieve is the device of choice for sieving fine powders. As a result of the air jet principle, the e200 LS offers maximum effectiveness with such materials.
SIEVE ANALYSIS AND FINENESS MODULUS Sampling Since the reason for sampling aggregates is to determine the gradation (particle size) of the aggregate, it is necessary that they be sampled correctly. The results of testing will re" ect the condition and characteristics of the aggregate from which the sample is obtained.
Powder Technology Inc. Powder Technology Incorporated (PTI) is a materials processing company with expertise in the total spectrum of particle modification with specialization in size reduction (including jet milling and hammer milling), air classification, vibratory screening and blending.
Standardized sieves in accordance with ISO 3310 or ASTM E11 are normally used for a sieve analysis. These standards describe the technical requirements for the sieves and methods for checking them. The choice of test sieve (diameter and mesh) depends mainly on the amount of sample and its particle …
