How to identify the number of screens and how to calculate the number of screens?

The simple method is to use the card r to measure, measure how many holes are on 1 inch that is, millimeters, this method is only suitable for 100 mesh or less, high mesh is not applicable, the other method is a magnifying glass with a scale, the scale magnifying glass is generally millimeters, you can count the number of holes in the millimeter, and then multiply by a thousand that is the number of holes in the screen, generally the high mesh is best to use an electronic magnifying glass with a scale, with the function of taking pictures, ranging and so on.

Number of mesh meshes. It refers to the length of one inch ( ), how many holes are arranged in total, that is, how many meshes. It's not a square millimeter.

It's a column of this length. For example, if the total length of the two leftmost holes in a field shape is, then it is two eyes, not four eyes.

Calculation method of mesh: wire diameter + aperture diameter) = mesh.

Screen calculation formula.

1. Mesh size: w = l n d, w - average mesh size (mm), l - adjacent mesh length (mm), d - average diameter of wire (mm).

2. The number of mesh meshes: 1 inch (the number of mesh holes in length.)

1 mesh = 1 aperture + 1 wire diameter mesh inch = number of meshes

3. Find the number of meshes = aperture + wire diameter).

Fourth, find the mesh size = mesh wire diameter.

The number of meshes is the number of holes in each square inch, and the number of holes in the side length of each inch. If you count specifically, it's not right. Because the thickness of the wire in the weaving net is different, the size of the hole will be different.

The mesh should indicate that the size of the hole is scientific and reasonable - it is the size of the particles after screening. Therefore, there is a table of correspondence between the sieve number and the hole edge length for viewing. The rules vary from country to country.

For example, the hole edge length of No. 32 sieve (i.e. 32 mesh) in China is 495 microns, the hole edge length of Taylor sieve No. 35 in the United States is 417 microns, and the pore edge length of No. 12 sieve in Germany is 490 microns. The side length of the former Soviet sieve is 500 microns,..All the countries speak of holes are square.

The way to determine the mesh number is to measure the side length of the hole.

The mesh number is the number of holes, which is the number of holes per square inch. Our country uses American standards. The screen pore size is measured in m.

The number of holes in the 25*25 eyepiece is the number of meshes.

The number of meshes, which is the number of holes, is the number of holes per square inch. The larger the mesh, the smaller the aperture. In general, the number of meshes.

Aperture (microns) 15000. For example, the pore size of a 400-mesh screen is about 38 microns; The pore size of the 500 mesh screen is about 30 microns. Because there is a problem of porosity, that is, because of the difference in the thickness of the silk used in weaving the net, it is different.

At present, there are three kinds of American standards, British standards and Japanese standards, of which the United Kingdom and the United States are phased.

Recently, there is a big difference in Japan. China uses the American standard, that is, the source can be calculated using the formula given above.

The micron and mesh comparison tables are as follows:

1 micron 1 m, m is the unit symbol for microns.

Mesh, also known as mesh, is generally expressed in terms of the maximum length of the particles.

The mesh is the size that represents the mesh size of a standard sieve. In Taylor's standard sieve, the so-called mesh is the number of mesh holes in the length of the 2.54 cm (1 inch) ridge, and is referred to as the mesh. The number of mesh refers to the number of mesh holes in the screen, which is the number of holes per square inch.

The larger the mesh, the smaller the aperture. In general, the mesh aperture (number of microns) is 15000 (the larger the mesh, the smaller this value is).

For example, a 200-mesh sieve means that this sieve has 200 sieve holes per 2.54 cm length of the screen, and its mesh size is 0.074 mm (the smaller the mesh, the larger the mesh size). A fineness of 200 mesh accounts for 70%, which means that the particle size content of less than 0.074 mm accounts for 70%. The pore size of the 400 mesh screen is about 38 microns; The pore size of the 500 mesh screen is about 25 microns.

Due to the problem of porosity, that is, because of the different thickness of the silk used in the woven net, the standards of different countries are not the same, there are currently American standards, British standards and Japanese standards and other standards, among which the United Kingdom and the United States are similar, and the difference between Japan is large. Most of the standards used in our country are American standards, that is, they can be calculated using the formula given above.

The number of screens commonly used in our country - micron (m) comparison table.

Due to habit and convenience, our country uses the following screen mesh mesh - micron comparison table in many luggage fields.

Conversion of mesh number and particle size diameter of the test screen.

1. Purpose definition refers to the number of hollow holes on the screen per square inch, 50 mesh on the bridge refers to 50 holes per square inch, 500 mesh is 500, the higher the number of mesh postures, the more holes. In addition to representing the eyelets of the screen, it is also used to indicate the particle size that can pass through the screen, and the higher the mesh, the smaller the particle size.

The mesh count is defined as the mesh size in one inch (

The length of the holes, how many holes are arranged, is how many meshes. Not a square millimeter, but a column of this length. For example, if the bureau has a field shape, and the total length of the two leftmost holes is, then it is two eyes, not four eyes.

Calculation method of mesh: wire diameter + aperture diameter) = mesh.

Screen calculation formula.

1. Mesh size: WLN D

w—average mesh size (mm).

l—the length of the adjacent mesh (mm), d—the average diameter of the wire (mm).

Second, the number of screen meshes.

1 inch (the number of mesh holes in length.)

1 mesh = 1 aperture + 1 wire diameter.

Mesh = number of meshes

3. Seek the number of age files = aperture + wire diameter).

Fourth, find the mesh size = mesh wire diameter.

The number of meshes represents the number of holes, and there is no simple mesh, and the correct way to express the number of meshes in the hall is to meet the banquet.

mesh cm. Or.

Eyes noisy inches.

Because silk silver mesh products are mainly exported, they are usually default.

The mesh inch is generally only recorded as the mesh (i.e. the number of holes contained in the millimeter length).

The screen does not talk about the "number of meshes", and the "number of meshes" is just a habit for people to describe the screen, which is difficult to overcome for a while. The screen is different from the general mesh product in that it has a strict mesh size, not the "mesh".

The so-called screen is different from the general mesh product. Rather, there are strict series of mesh sizes. In addition, there are mesh products that have the function of grading and screening object particles and are recognized by industries, institutions and standards.

The screen size is not isolated, it is composed of a series of mesh sizes, the purpose is for grading screening.

The screen is made of woven metal wire or fiber wire, with a pore size. It can remove different types and small suspended solids, and the screen separation has the advantages of simplicity, high efficiency and low operating cost.

It is generally used for small-scale wastewater treatment. There are many kinds of screens, and the main two are vibrating screens and hydraulic screens.

The number of mesh mesh refers to the number of holes arranged in a total of one inch ( ) length, which is the number of meshes.

The screen type is a representation of the screen printing plate in terms of the number of mesh and the diameter of the mesh. In other words, the size and strength of the screen mesh are the main indicators to measure whether it is suitable for printing or not. The diameter of the mesh is thick, and the screen is strong, so it is durable.

The reasonable mesh size makes the printed screen itself provide a reasonable amount of pulp and is placed on the surface of the fabric, and the selection of a reasonable screen mesh mesh also provides a basis for the reasonable mesh size.

Select the bullet points

The screen is the inevitable product of the refinement of coal mines, iron ores, industries and chemical raw materials, and is the composition of tiny cells for the development of society, which indirectly or directly affects the development of society. The selectivity of the screen is mainly selected according to the characteristics of the screen.

The selectivity of the screen is mainly based on the characteristics of the screen, the material, the wire diameter, the mesh, the length of the life, the height of the screen, etc. These elements of the screen are mutually influencing each other. The thickness of the cavity diameter of the wire cover directly affects the service life of the screen and the number of screens.

The wear resistance, corrosion resistance, high temperature resistance, and magnetic properties of the material are directly related to the number of screens.

The number of meshes refers to the number of holes in the screen per inch.

1 mesh 4000 μm.

50 mesh means that there are 50 holes per inch, and 500 mesh means that the ridge is 500 large, and the higher the number of meshes, the more holes. In addition to the eyelets of the screen, it is also used to indicate the particle size that can pass through the screen, and the higher the mesh, the smaller the particle size.

Notes:The mesh is the number of holes, the number of holes per inch. The larger the mesh, the smaller the aperture. In general, the mesh x aperture (number of microns) is 15000.

For example, the 400 mesh aperture is about 38 microns; The pore size of the 500 mesh screen is about 30 microns. Due to the existence of the opening price problem, that is, due to the different thickness of the silk used in weaving, the standards of different countries are also different, there are three kinds of American standard, British standard, and Japanese standard.
