　　According to the structure of polyurethane sieve plate, there are three types: inlaid bolt connection, bead line connection and sieve hook connection.

　　For example, the type of bead line connection: first place the polyurethane sieve plate on the screen surface and then install it according to the supporting beam structure of the sieve.Generally, on both sides of the sieve machine, a length of u-shaped iron plate of suitable length should be drilled along the upper layer of the sieve plate in the direction of the feeding, and the hole should be drilled at a proper distance. Then the sieve plate should be firmly fixed in the middle with the bottom support beam.The supporting beams and the contact surfaces of the slender plates and sieve plates are filled with rubber strips (using old rubber hoses).It can also be installed in this way above the supporting beam in the middle of the screen.

　　If the sieve plate is not installed as required, it may cause it to shake up and down on the surface of the sieve plate, and the friction and collision with the steel support beam for a long time will seriously affect the service life of the sieve plate.

　　1. Specifications of polyurethane sieve plate:

　　(1) The standard type in the table is common product with medium screening efficiency and service life;Slightly higher efficiency type, slightly lower life;Life efficiency slightly lower, longer service life.

　　(2) The mesh size in the table generally refers to the square hole. If you need different square holes or holes of other shapes, you can consult our company.

　　2. Characteristics of polyurethane sieve plate:

　　(1) The longitudinal and transverse strips of the screen are made of highly wear-resistant polyurethane material, and the steel wire includes steel wire.Service life is 3 to 10 times longer than traditional metal mesh.

　　(2) Unique structure, suitable elastic and plastic forces can not only reduce the paper jam, but also reduce the adhesion caused by the high-frequency vibration of the second harmonic of the screen.The utility model has a high opening rate and a high screening efficiency.

　　(3) Both sides of the screen have elastic tensioning hooks.The machine has light weight, good flexibility, easy transportation and storage, easy installation and disassembly.

　　(4) The screen can effectively absorb the impact, reduce the noise and improve the working environment.

　　3. Purpose of polyurethane sieve plate:

　　Metallurgy (iron ore, limestone, fluorite, cooling blast furnace slag, coke and other raw materials), non-ferrous metal, yellow, coal, chemical, building materials and hydropower engineering, abrasive waste treatment, quarries and other industries, washing and screening, classification and other industries.

　　Polyurethane screen board manufacturer: the new structure screen board of various format sizes and mesh sizes is especially suitable for applications with high impact force, high hardness and high wear resistance.Wear-resistant sieve plate is used for fine crushing and screening of iron ore, classification of raw coal, gold and building materials, and screening of gravel for hydropower and nuclear power projects.
