400mm Standard Test Sieve

What is 400mm Standard Test Sieve?

400mm Standard Test Sieve, the diameter of the sieve frame is 400mm, the sieve is produced in strict accordance with the GB6003.1-2012 standard, and is selected by a tool microscope. Our company adopts the marking method of mesh/wire diameter for the specifications (because the mesh number is a relative unit, the mesh number refers to the number of holes and wires on the length of 1 inch 25.4 mm. The same mesh number, different wire diameters, and different holes).

400mm Standard Test Sieve can be installed on the sieve or test sieve machine to classify the particle size composition of various powder materials.

What are the types of 400mm Standard Test Sieve screens?

Metal wire woven screen: widely used, low cost, wide application range, light and durable. The mesh shape of this kind of sieve can only be square holes, the mesh size is between 2.36mm and 0.02mm, and the mesh size of triangular holes can reach 0.005mm (5 microns), and the mesh is woven according to B6003.1-2012 standard . Comply with international standard ISO3310-1: 1990 R20/3, R20, R40/3 series.

Punching plate screen: It is a kind of test sieve grid that punches out a fixed shape and size of sieve holes directly on the steel plate or other sieve plate materials with a punching machine, and is processed according to the GB6003.2-2012 standard. Comply with international standard ISO3310-2: 1990 R20/3, R20, R40/3 series. It is suitable for materials with relatively high density, relatively large impact on the screen surface, and irregular shapes. The shape of the screen hole is square or round, and customers can customize it according to their needs.

Electroforming screen: produced by electrochemical methods, with the highest precision, which can be accurate to 1 micron, and is often used in high-precision laboratory occasions.

400mm Standard Test Sieve Features

1. The screen frame is made of SUS304 (0Cr18ni9) stainless steel stretched and polished, with a wall thickness of 0.6 mm. The overall shape is durable and non-magnetic.

2. The screen mesh and screen frame are fixed by soldering without loosening, and can withstand high temperatures below 300 degrees.

3. Guaranteed accurate size. The test sieves of the same model have the same mesh holes produced at different times to ensure the consistency of detection. The sieve can be sieved to 0.025-3mm.

4. Equipped with time relay control, it can automatically shut down at a fixed time.

How do 400mm Standard Test Sieve work?

The 400mm Standard Test Sieve uses a vertical vibrating motor as the vibration source of the whole machine. The vibration motor drives the upper vibrating plate to vibrate, and then transmits to the upper vibrating plate placed on the sieve frame through the vibrating plate. Sieve the material particles smaller than the pore size of the sieve to the lower sieve frame, so that only the same particle size materials are left in each layer of test sieves, so as to achieve the separation of different particle sizes and determine the particle size composition of the materials.

400mm Standard Test Sieve Application

400mm Standard Test Sieve are widely used in research and production, laboratories, quality inspection rooms, and laboratories of universities and colleges in the fields of abrasives, geology, metallurgy, pharmacopoeia, metallurgy, chemical industry, medicine, powder, building materials, national defense, and geology. Accurate screening, filtration and detection of particle size structure, liquid-like solid content and sundries of powdery and powdery materials,

1. Sieve flour with 40 mesh for commercial use, 50 mesh for household use, and 60 mesh for baking.

2. Mask powder, pearl powder 80-120 mesh. Pearl powder 100-150 mesh (different grinding thickness).

3. Filter soybean milk and traditional Chinese medicine - generally 80 mesh.

4. Soybean 5 mesh, mung bean 10 mesh, ordinary rice 12 mesh, southern fragrant rice 14 mesh, millet sesame 20 mesh.

5. Tenebrio eggs are 12 meshes, and filter feces are 30 meshes.

6. Buckwheat husk is about 12 mesh.
