In the first two issues, we introduced quartz sand and quartz sand color sorter. Maybe some friends are not very clear about the units used to measure the grain size of quartz sand in the industry, so this year we will learn about the "target".

Mesh refers to the number of holes per inch of screen. 50 mesh means that there are 50 holes per inch, and 500 mesh means 500 holes. The higher the mesh, the more holes. In addition to indicating the pores of the screen, it is also used to indicate the particle diameter of the particles that can pass through the screen. The higher the mesh number, the smaller the particle diameter.

The particle size of powder is called particle size. Because the shape of particles is very complex, there are usually several expression methods such as screening particle size, sedimentation particle size, equivalent volume particle size and equivalent surface area particle size. The screening particle size is the size of the mesh through which the particles can pass. It is expressed by the number of mesh holes in the mesh with a width of 1 inch (25.4mm). Therefore, it is called "mesh number". There is no unified technical standard for particle size at home and abroad, and each enterprise has its own definition and expression method of particle size index.

Comparison table of standard mesh size

It can be seen from this definition that the size of mesh determines the size of screen aperture. And the size of the mesh aperture determines the particle size of the sieved powder. How small is the 120 item material? You can find the answer through the item comparison table.

Taiyiming quartz sand color separator

Dalian taiyiming quartz sand color separator, selectable particle size range: 4-120 mesh, large range of selectable material mesh, strong target recognition ability, large production capacity of single slide, high material cleaning rate and low carry out ratio.

This machine is equipped with embedded software, which can greatly reduce the error; Equipped with a 10.2-inch touch screen, easy to operate; Using high-performance CCD sensors, even small substances as small as 0.125mm can be selected. Taiyiming quartz sand color sorter is a high-performance color sorter that integrates self-detection and automatic sorting capabilities to minimize errors.
