  • Laboratory Sieves and Sieve Shakers from Cole-Parmer

    When stacked on a sieve shaker, the top test sieve has the largest mesh size and the bottom one the smallest mesh size. Pans and covers are available to complete your stack. Sieve shakers provide uniform motion to ensure the reproducible results you can't get from hand sieving.

  • Sieving methods of sieve analysis

    The air jet sieve is a sieving machine for single sieving, i.e. 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.

  • MEMBRANE SCREENS WITH VIBRATING SIEVES

    the sieve is flexible and vibrates like a membrane. Besides, because the sieves are mounted on the immobile riddles, the amplitude increases from zero to the value of vibration amplitude of the pushing rods. This is reflected by a surface module discussed in the previous section. The sieve motion was proposed to be described by a

  • Sieve analysis - Wikipedia

    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 each sieve as a fraction of the whole mass.

  • Sieve - Wikipedia

    A mesh strainer, also known as sift, commonly known as sieve, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net or metal.
