Product Overview
What Is a Test Sieve?
A test sieve is a measurement instrument that uses a metal mesh screen (a screening or sieving medium, namely a woven wire screen, perforated metal screen, or electroformed material) with apertures of uniform size and shape (most often, square, round or slotted holes) mounted on a rigid frame to help generate a reliable particle size distribution curve.
The rigid frame is most often made of stainless steel 304 in a cylindrical configuration.
Typically, a number of test sieves with variable apertures are stacked on top of each other to separate particles of different sizes to detect the size and size distribution of particles in a material sample.
What Is a Sieve Stack?
A sieve stack is a series of test sieves placed on top of each other in a single column used to separate particles of different sizes to detect the size and size distribution of particles in a material sample.
In the sieve stack, the top test sieve has the greatest mesh size, and the bottom test sieve has the smallest mesh size. The receiving pan is at the bottom most of the sieve stack, the test sieves are stacked on top of each other with the smallest openings at the bottom and the largest openings at the top in ascending order, and the cover is at the topmost level if any.
The sketch for the sieve stack is shown below:
What Is a Wire Mesh Sieve?
A wire mesh sieve is a test sieve, which always houses a woven wire screen (a screening or sieving medium, usually made of galvanized steel, stainless steel, brass or bronze) with uniform square openings that allow for accurate particle screening.
The woven wire screen is usually mounted on a rigid round stainless steel frame.
Our product model TS-200 wire mesh sieve is illustrated in the picture below:
In terms of our product models TS-80, TS-100, TS-200, TS-203, TS-300, TS-305 and TS-400 test sieves,
they have structural characteristics as below:
1. Durable Construction
Each test sieve is carefully crafted with 2Nos polished seamless stainless steel frames in a cylindrical configuration and 1No high-quality screening medium. These Standard Test Sieves are built to withstand rigorous testing conditions, ensuring long-lasting use.
The two polished seamless stainless steel frames are the inside frame and the outside frame.
Either of the two frames is drawn from one piece of stainless steel without any seam. The seamless frames are designed to enhances structural integrity and eliminates potential weak points.
Please take note that the outside frame is complete with an extended bottom (sieve skirt). The seamless sieve skirt is designed to fit all frames, bottom pans, and nesting pans of the same diameter for convenient stacking.
One screening medium can be either 1No high-quality woven wire screen or 1No perforated plate screen.
2. Versatile Edges
The inside polished seamless stainless steel frame has the top edge, which has been rolled for comfortable and safe handling purposes, and the bottom edge, which has been bent into a circular strip of hoop for purposes of preventing loss of sample materials between the metal screen and the frame.
In addition, the hoop is also used to receive the metal screen that can be hand soldered onto its back face when the metal screen is tightened up in terms of coarse mesh screens or perforated plate screens.
3. Precise Apertures
Whether woven wire screens or perforated plate screens, they are of precise apertures in strict accordance with ISO 3310, ASTM or other specifications.
For fine sieving, our skilled workers can have a woven wire screen clamped tightly between the two frames by using a special technology, instead of the hand soldering process.
Evenly tightened screen panels ensure accurate analysis.
Three parts of our product model TS-80, TS-100, TS-200, TS-203, TS-300, TS-305 and TS-400 test sieves are illustrated in the picture below:
A Brief Description of Product Model TS-600 Stainless Steel Woven Wire Mesh Sieves
Each of our product model TS-600 stainless steel woven wire mesh sieves consists of three stainless steel components: A stainless-steel sieve frame at the top, a stainless-steel sieve skirt at the bottom, and a stainless-steel woven wire screen at the middle.
Furthermore, our stainless-steel frames are constructed by using the spot-welding process that uses the combination of pressure and heat through an electrical current to join two metal pieces. This technique is the best choice for sheet metals only, as concentrated current eliminates resistance from the spot and facilitates the fusion process.
The skirt is designed to fit all frames, bottom receiving pans, nesting pans, and blank spacers of the same diameter for convenient stacking.
It should be noted that the woven wire screen is stretched fully, and then fixed tightly and closely in between the frame and the skirt in a specially combined manner.
