Screen product overview:
The screen mesh is mainly used for rotary vibrating screen, linear vibrating screen, mining screen, circular vibrating screen, roller screen, arthropod screen, etc. the screen mesh has a special mesh for small rotary vibrating screen and a special mesh for large mining screen. The screen mesh is divided into stainless steel screen, ordinary industrial screen, stainless steel welded screen, manganese steel wire screen, polyurethane screen plate comb plate, cast screen plate, etc. the screen mesh can be customized according to different requirements. Vibrating screen and vibrating motor
Wire mesh:
The screen plate of the metal wire woven mesh is woven with the metal wire with the bending buckle, and the screen hole is square or rectangular. Its advantages are: light weight, high opening rate; and in the screening process, due to the elasticity of the wire, high-frequency vibration is made, which makes the fine materials adhering to the wire easy to fall off, so as to improve the screening efficiency. It is suitable for grading operation of medium and fine materials. But its disadvantage is its short service life.
There are two types of mesh screen: coarse hole and fine hole. The manufacturing materials of coarse mesh mesh are low carbon structural steel wire, spring steel wire and stainless steel wire. The mesh size is generally 4-125mm, and the diameter of steel wire is 1.6-12.5mm. The fine mesh is usually made of low carbon steel, brass, tin, tin surface copper, stainless steel and other materials, with a special knitting machine. The opening rate is 36% - 80%, and the mesh size is 0.03-16mm. The applicable screen angle is 18 ° - 30 °.
Waveform network:
Wave screen is to press the screen bar into wave shape along the transverse direction, and the wavelength is determined by the size of the sieve hole. Double wave net is to arrange one piece of screen bar which is pressed into wave shape. Two screen bars can be stacked into a row of square holes as shown in the figure. The curvature of screen bar waveform is 90 °.
Single wave network:
The single wave screen is a wave shaped screen bar, and a straight screen bar forms the mesh group, and then the mesh group is combined to form the screen bar as shown in the figure. There are two kinds of bending degree of screen bar waveform: 90 ° and 58 °. Whether it is a single wave net or a double wave net, the screen bars shall be clamped with sheet steel or tied with steel wire, and the spacing between the clamping plates shall be 400-800mm. The material of screen bar is spring steel or strip steel plate. There are more circular and flat rectangles used for screen section, and inverted trapezoid is also used. The mesh size range is 3-30mm. Because the screen bar produces its own secondary vibration when it works, this kind of screen is installed on the vibrating screen, which greatly reduces the blocking of the screen and improves the screening efficiency. It can also improve the ore washing efficiency.
