300mm Test Sieve

Introduction of 300mm Test Sieve

300mm Test Sieve is a stainless steel precision test sieve produced by Dahan Machinery, which can be used in the laboratory for particle size analysis of powder/granule/material and content detection of liquid material; the sieve conforms to the national standard GB6003.1-1997 and is selected by a tool microscope; 300mm Test Sieve has metal woven screens, perforated plate screens and electroformed screens with mesh size from 0.038mm to 2.36mm. 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).

Working principle of 300mm test sieve

The vibration generated by the vibration motor causes the screen frame and the material on the screen to move relative to each other. The material particles smaller than the screen aperture will pass through the screen and fall into the lower screen frame, while the material particles larger than the screen aperture will remain on the screen, thus achieving separation of different particle sizes.

The supporting structure of the 300mm test sieve

300mm test sieve is a commonly used laboratory screening equipment. It is mainly composed of a screen frame, a screen mesh, a screen bottom, a clamping device and a vibration motor. The screen frame is usually made of stainless steel, which is corrosion-resistant and high-temperature resistant. A fixing device is provided on the top of the screen frame to firmly fix the screen mesh. The screen mesh is the core component of the screening, and the material is diverse, such as stainless steel woven mesh and punched plate, etc. Screens of different apertures can be selected according to the screening needs.

Advantages of 300mm test sieve

Prevent clogging: 300mm standard test sieve usually has a suitable mesh size and design, which can effectively prevent particles from clogging in the mesh and keep the screening unobstructed.

Accurate screening ability: 300mm standard test sieve has a high-precision mesh size, which can accurately screen particles of different particle sizes and provide accurate particle analysis data.

Dust control: The test sieve is usually designed with a dust sealing device to reduce the flying of dust, keep the experimental environment clean, and protect the health of the operator.

Efficiency: Through the multi-layer screen design and precise screening mechanism, the 300mm standard test sieve can improve screening efficiency and save experimental time.

As a commonly used laboratory equipment, 300mm test sieve plays an important role in many fields.In the agricultural field, it is used to screen seeds, remove impurities and broken seeds and soil samples, and analyze the particle size composition. In the scientific field, it is used to screen various material powders, study the microstructure and properties of materials, and can also be used to screen soil and water samples, etc., and analyze environmental pollutants.

300mm Test Sieve mesh type

Wire woven mesh: mesh size between 2.36mm and 0.02mm, square mesh, commonly used, low price.

Perforated plate screen: the mesh size ranges from 0.2 to several hundred millimeters. There are two types of round hole and square hole screen. It is mainly used for large meshes and is often used for the detection of large particle materials such as soil, asphalt, and coal.

Electroforming screen: the precision can reach 1 micron, mainly used in high-precision occasions in the laboratory, and each mesh can be within the average error range. As a professional manufacturer of standard sieves, it is necessary to have a tool microscope and a projector. The tool microscope is used to check the accuracy of the mesh, and the arithmetic mean method is used.

The sieve size of the sieve produced by Dahan Machinery guarantees the same type of 300mm Test Sieve, and the meshes produced at different times are the same to ensure the consistency of the test and detection. The hole size of the imported Taylor screen is similar to that of GB6003.1-1997. For example, the mesh size of No. 140 in China is 106 microns; the mesh size of No. 140 # Taylor screen in the United States is 105 microns; the mesh size is 105 microns; make.

300mm Test Sieve Mesh and Aperture

The so-called mesh number of 300mm Test Sieve refers to the particle size or thickness of the material. The general definition refers to the sieve within the area of 1 inch*1 inch. The material can pass through the sieve, and the number of holes in the sieve is defined as the mesh number. . For example, 200 mesh means that the material can pass through a screen with 200 meshes within 1 inch*1 inch. By analogy, the larger the mesh number, the finer the particle size of the material; the smaller the mesh number, the larger the particle size of the material. The sieving particle size is the size of the sieve holes that the particles can pass through the sieve, expressed as the number of sieve holes in a 1-inch (25.4mm) wide sieve, so it is called the mesh number.
