ASTM E11 ISO 3310 Stainless Steel Test Lab Sieves Grain Sieves

ASTM E11 and ISO 3310 Standard Stainless Steel or Brass Test Sieves from Tec-Sieve
 

What Is a Test Sieve?
A test sieve is a scientific screening instrument, which usually uses a screening or sieving medium (woven wire screen, perforated metal screen, or electroformed material) with openings of uniform size and shape mounted on a rigid frame to help generate a reliable particle size distribution curve.
The rigid frame is usually made of stainless steel or brass in a cylindrical configuration.
Typically, a number of test sieves with various mesh openings are stacked on top of each other to separate the particles of a material sample based on their size.

Structural Characteristics of TS Series
In terms of TS-80, TS-100, TS-200, TS-203, TS-300, TS-305 and TS-400 test sieves
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.

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

Tec-Sieve has been using multiple packing materials to perfectly protect our standard test sieves in transit.
These materials include, but not limited to, bubble wrap, cartons, and plywood cases.
 

Some typical applications are as follows:
The sizing of chemical and pharmaceutical crystals and powders;
The grading of coal and ores;
Determining the efficiency of a crusher; grinder or industrial screening unit;
Cement testing;
Classifying silt, soil, sand, gravel and other materials encountered in civil engineering work; Checking the state of a fluidized catalyst in an oil refinery.
