Definition
The so-called screen mesh is a different and general mesh product, but has a strict series of mesh sizes, and has mesh products that conform to industry, organization, and standards for classifying and screening the object particles. The screen does not talk about “mesh”, “mesh” is just a habit of people to describe the screen, it is difficult to overcome. A screen is different from a general mesh product in that it has a strict mesh size rather than a “mesh”. The screen size is not isolated, it has a series of mesh sizes for the purpose of grading screening.
The screen is woven from wire or fiber and has a hole diameter of 0.15~1mm. It can remove and recycle different types and small suspensions. Screen separation has the advantages of simplicity, high efficiency and low operating cost. Generally used for smaller wastewater treatment. There are many kinds of screens, the main two are vibrating screens and hydraulic screens.
Characteristics
Features of metal screen: 1. Weaving precision; 2. Mesh rule; 3. Reliable filtration accuracy; 4. High compressive strength; 5. High temperature resistance and chemical corrosion resistance; 6. Good wear resistance; 7. Good Formability.
Selection point
Screen is an inevitable product of fine refinement of coal, iron ore, industry and chemical raw materials. It is a component of tiny cells that the society is moving forward, indirectly or directly affecting 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, material, wire diameter, mesh, length of life, price and so on. These elements of the screen are mutually influential. The thickness of the wire diameter directly affects the service life and price of the screen. The wear resistance, corrosion resistance, high temperature resistance, and presence or absence of magnetic properties of the material directly affect the price of the screen.
