Custom High-Performance Stainless Steel Mine Sieving Filter

Introduction of general knowledge of wedge wire mine sieving screen

Wedge wire mine sieving screen is a welding type filter screen, which has a large effective area and high screening efficiency. The rectangular mesh screen is often used for plate-shaped materials, and the mesh is not easy to block.

Wedge wire mine sieving screen is a kind of metal mesh structure element used for screening and filtration. It is widely used in screening, filtration, dehydration, desliming, and other operations in many industries.
It has high strength, rigidity, and bearing capacity, and can be made into various shapes of rigid screening and filtering devices. Wedge wire mine sieving screen material: low carbon steel wire, high manganese steel wire, stainless steel wire.
Product classification: stainless steel welded screen, slit screen, sieve plate basket, welded vibrating screen, cylinder screen, DSM screen.
Product features: easy to leak, wear resistance, corrosion resistance. The cross-section of the mesh is trapezoidal. The gap is narrow at the top and wide at the bottom. It is widely used in mining, coal, petroleum, chemical fertilizer, grain, salt, environmental protection, and other industries.

In the passive film on the surface of the wedge wire mine sieving screen, the parts with weak corrosion resistance form pitting corrosion reaction due to self-excited reaction, and small holes are formed on the screen. In addition, chloride ions are close to each other, forming a strong corrosive solution, which accelerates the corrosion reaction. There is also intergranular corrosion cracking in stainless steel, all of which destroy the passive film on the surface of stainless steel. Therefore, the wedge wire mine sieving screen surface must be regularly cleaned and maintained to maintain its gorgeous surface and prolong its service life.
When cleaning the surface of the wedge wire mine sieving screen, it is necessary to pay attention not to scratch the surface, and avoid the use of washing liquid, steel ball, grinding tools, etc. of bleaching components and abrasives. In order to remove the washing liquid, the surface should be washed with clean water at the end of the washing.

The wedge wire mine sieving screen is made of steel plate punching and rolling, so it is light in weight and cheap in price. According to the needs of users, there are different anti-corrosion coatings, which can improve the service life of water wells.
It can be connected in many ways, so it is easy to operate. The gap of the bridge hole can be changed according to the user’s requirements so that the user can obtain satisfactory bridge porosity.
The special pore structure of the water well filter enhances the mechanical strength of the water well filter. Therefore, it has high mechanical strength. According to the user’s requirements, the bridge type water well filter of any diameter can be provided, which greatly facilitates the user.
In addition to water inflow, it can also prevent the particles of soil or rock around the good wall from flowing into the well and silting the good pipe. At the same time, it also plays the role of supporting and protecting the good wall, so that the pumping hole can be used normally.
In some hard fracture and solution aquifer, the good wall is stable and there is no loose filling material. When pumping water, it is not necessary to install a filter pipe. In a loose pore aquifer or broken bedrock aquifer, it is necessary to install a suitable filter pipe.
In agricultural water supply wells, cement gravel filter pipes are also commonly used. In fact, the brick and wood walls of civilian wells are also used to filter and purify water resources.

The structure strength of an ordinary metal pipeline is high, but its corrosion resistance is relatively poor, and its service life will be short. If it is used for a long time, the inner wall is easy to rust and scale, and it is easy to bring obstacles and hidden dangers to the pipeline transportation system, and it will also lead to water pollution. The corrosion resistance of stainless steel pipe and copper pipe is relatively high, but the cost of the project is very high, ordinary buildings can not afford such a high price.
With the popularization and application of wedge wire mine sieving screen, it has been selected as pipeline material by many projects, and also known as the ideal well filter.
