The laminated composite fine screen is at least 10% higher than the hee numerical control vibrating screen. Due to the change of screening form, the het series multi-layer cnc high-frequency composite fine screen is divided into two layers. The material is screened by polyurethane screen, diluted and recycled, and then passed through composite screen to achieve secondary screening effect, with high screening rate.

Application of laminated composite fine screen:

It is suitable for dry and wet screening, grading, dehydration and roughing of fine materials. It is suitable for dehydration and classification after metallurgical beneficiation and grinding. It can reduce the grinding cycle load, improve the processing capacity of the ball mill, and quickly improve the grade of iron concentrate. Especially when the iron concentrate grade is 68-70%, the reverse flotation process is better.

Analysis on application of laminated composite fine screen beneficiation:

The screening efficiency and iron concentrate grade are improved. A series of problems restricting beneficiation production due to large material circulation on the screen are solved. The quick control of particle size composition under the screen not only reduces the adverse impact of coarse particles on concentrate quality, but also reduces the tailings metal loss caused by over grinding and over grinding.

On the premise of ensuring and improving the quality and particle size of the concentrate, the necessary conditions are created for improving the processing capacity of the primary mill.

The laminated composite fine screen is a single piece of metal wire mesh formed by welding, rolling or sintering metal woven mesh, metal welded mesh or metal punched mesh with the same or different mesh diameters. Different scenes have different structure composition and production process.

Laminated composite fine screen is a new type of filter material with high mechanical strength and good rigidity of overall structure, which is made by special lamination and vacuum sintering process. The mesh of each layer of metal wire mesh is interlaced to form a uniform and ideal filtering structure, which not only overcomes the shortcomings of low strength, poor rigidity and unstable mesh shape of ordinary metal wire mesh, but also can reasonably match and design the aperture and strength characteristics of materials, so that it has excellent filtering accuracy, filtering impedance, mechanical strength and strength, and its wear resistance, heat resistance, processing performance and comprehensive performance are obviously superior to sintered metal powder, ceramics, fibers, filter cloth Filter paper and other types of filter materials.

The laminated composite fine screen is generally divided into five layers, consisting of four parts: protective layer, filter layer, separation layer and support layer. The product not only has uniform and stable filtering accuracy, but also has high strength and stiffness. It is an ideal filter material for occasions with high compressive strength requirements and uniform filter particle size. Because its filtering mechanism is surface filtering, the mesh is smooth, and it has excellent backwashing performance, which can be reused for a long time. Especially suitable for continuous automatic operation process, which is incomparable to any filter material. Sintered screen materials are easy to form, process and weld. Can be processed into round, cylindrical, conical, corrugated and other forms of filter.
