What is the test sieve?

31 Mar 18

Test Sieve HS Code: 8474100000
Diameter: 8 inch, 12 inch, 75mm, 200mm, 300mm
Optional Material: stainless steel, brass
Screen Type: Woven Wire Mesh, Perforated Plate, Electrical Forming
Standard: ISO3310, ASTM, TYLER, JIS, DIN, BSI
It can be mounted on a test sieve shaker.

Overview:

Test sieve is also called test screen, testing sieve, lab sieve, experimental sieve, standard sieve, inspection sieve, standard test sieve, sampling sieve, particle sieve, analysis sieve, checking sifter, sieve set, pharmacopeia sieve, earth-rock sieve, soil sieve, sediment sieve, coal sample sieve, sieve set grizzly, standard screening test fixture, tyler sieve, stainless steel standard sieve etc.

 

Function:

Test sieve is a tool for material particle size classification and detection. It is a sieve that is inspected, identified and agreed by the designated institution, which is an important symbol that is different from general sieve.

 

Application:

The test sieve is mainly used for particle size analysis and detection, widely used in abrasive, geological prospecting, metallurgy, pharmacopoeia, chemical building materials and other industries for screening and tesing of particle materials.

 

Structure and Composition:

Test sieve frame, screen cover and screen bottom are made of high quality stainless steel.

(1) screen frame:

  1. The screen frame adopts high quality stainless steel and one-time drawing shaping, surface polishingand with fine appearance. Closely cooperate, no leakage of material and water. The wall thickness is 0.6~0.7mm. The surface surface is so bright that it can serve as a mirror. Integral forming, strong and durable, no magnetism.
  2. The screen and frame are fixed by tin soldering. The connection is firm, no slack, no gap and no jam.
  3. It can be resistant to 400 degrees celsius high temperature, and can be used for inorganic and organic solution.
  4. Due to the use of stretching and forming, the dimensions are unified. And the upper and lower sieve frame adopt conical surface matching (consistent with the valve sealing method),which are completely sealed after the upper and lower installation. Meanwhile, due to the electrical conductivity between the frames, avoiding the electrostatic adsorption (consistent with the structure of the Taylor screen in the United States). The fine granule is smoothly flowed. If the user request, it also can be equipped with the sealing ring, but considering the electrostatic problem and the seal has reached the requirement, we generally do not use.
  5. Height:50mm (General), 23mm (Short)
  6. Diameter of the frame: 8 inch, 12 inch, 75mm, 200mm, 300mm

 

(2) mesh screen:

The mesh is accurate. The screen is marked by standard screen size and mesh size, so the mesh with the same specification is identical at different time.

The commonly used material of screen is brass, tin bronze and stainless steel.

2.36um~100um adopt nickel plating, which can not only improve the precision of mesh hole, but also prevent the mesh deformation. hardness, wear-resisting and durability of mesh holes. Strong, wear-resistant and durable.

 

Category:

According to the screen material, the test sieve is divided into woven wire mesh test sieve, metal perforated plate test sieve and electrical forming test sieve.
