Stainless Steel Test Sieves

What is Stainless Steel Test Sieves?

Stainless Steel Test Sieves are made of SUS304 stainless steel, with a wall thickness of 0.6mm. The surface is smooth, not easy to store materials, can withstand high temperatures of 400°, resistant to acid and alkali corrosion, not easy to rust, and non-magnetic. It is necessary to prepare granular samples. Stainless steel test sieves of different apertures. The purpose of sieving is to separate the particles that exceed the limit and continue to crush them to the specified particle size, so as to ensure that the inhomogeneous substances reach a certain degree of dispersion and reduce the reduction error in each sample preparation stage.

What are Stainless Steel Test Sieves used for?

Stainless Steel Test Sieves is a tool for particle size classification and particle size detection of granule and powder materials. It can accurately separate materials and analyze particle size content composition.

Stainless Steel Test Sieves Application

Stainless Steel Test Sieves are used for particle size analysis of granular materials. Widely used in the screening and detection of granular materials in abrasives, decan, metallurgy, pharmacopoeia, chemical building materials and other industries. Specific materials include: flour, starch, corn flour, medicine powder, grain, powder, aggregate, feed, coal powder, etc.

What are the different materials of Stainless Steel Test Sieves?

Stainless Steel Test Sieves material has 304 stainless steel and 316L stainless steel.

304 stainless steel: resistant to high temperature of 800 ° C, with corrosion resistance, easy processing, good toughness and other characteristics. When the requirements for corrosion resistance are not high, 304 stainless steel is better because the unit price of 304 stainless steel is lower than that of 316 stainless steel.

316L stainless steel: It is a material with lower carbon content in the same series of materials. Compared with 304, 316L stainless steel has stronger chemical corrosion resistance, and is more resistant to high temperature creep, stress rupture and tensile strength than other steel grades. When the scene has higher requirements on corrosion and heat resistance, 316 stainless steel is better.

304 and 316L Stainless Steel Comparison
Contrast	304	316L①	Remark
Price	Low	high	304 stainless steel has excellent performance, low unit price, and is more widely used
Molybdenum content %	0	2-3	The higher the Mo content, the better the corrosion resistance and heat resistance.
Nickel content %	8-10.5	10-14	The higher the Ni content, the better the corrosion resistance and heat resistance.
Carbon content %	<0.08	0.03	The higher the Carbon content, the harder the city ② the lower the Carbon content, the better the welding performance
Notes	①When we refer to 316 stainless steel, we mean 316L stainless steel
	②Carbon is a strong austenite forming element, which can significantly improve the strength of steel, but the higher the carbon content in carbon steel, the worse the plasticity, and carbon also has an adverse effect on corrosion resistance

Stainless Steel Test Sieves Mesh

Mesh and aperture conversion formula: 1μm = 1 micrometres (micron) = 0.001 millimetre (millimeter)

The number of stainless steel test sieves is the number of holes, which is the number of holes per square inch. The larger the mesh number, the smaller the aperture. Generally speaking, mesh number * aperture (number of microns) = 15000. For example, the aperture of a 400-mesh screen is about 38 microns; the aperture of a 500-mesh screen is about 30 microns. Due to the problem of porosity, that is, because of the different thickness of the wire used in weaving the net, the standards of different countries are also different. There are currently three types of American standards, British standards and Japanese standards, of which the British and American standards are similar. , the difference is larger in Japan. Our country uses the American standard, that is, it can be calculated by the formula given above.

How to use Stainless Steel Test Sieves?

One: Adjust the time as needed. The first two digits of the time relay are minutes, and the last two digits are seconds. Adjust the reading of the time relay to the desired time.

Two: Put the stainless steel test screen frame into the equipment, tighten the nuts, and start the machine.

Three: When the running time of the test sieve is equal to the set time, the test sieve will automatically shut down, and carefully take out the sieve frame.
