Working principle and structural characteristics of reversible sieve bend screen
Sieve bend screen is mainly used for pre dewatering, desliming, demineralization and graded slime recovery of materials in coal preparation plant and concentrator. It can also be used together with water cyclone to effectively classify, dehydrate, desliming and demineralize fine materials. The screen machine is composed of a screen box with a wrap angle of 45 degrees and a radius of curvature of 60 degrees and a radius of 2030mm.
The sieve bend screen plate surface and screen frame adopt pivot specific structure, which can rotate 180 degrees and prolong the service life of the screen surface. The wedge wire screen plate is turned over by the feed box, screen box and screen machine base shaft to realize the position adjustment of the feed end and discharge end, achieve uniform wear, prolong the service life, and operate flexibly and conveniently. It has also been widely used in metallurgy, chemical industry and other industries.
Working principle: the dewatering principle of sieve bend screen vibrating screen is to separate the slime water by cutting the slime water by the sharp edges on the feeding side of the screen strip; According to the application occasion and the great difference of material moisture, the sieve bend screen plate is divided into vibrating sieve bend screen plate and unpowered sieve bend screen plate. HS sieve bend screen plate is turned over by the feed box, screen box and screen machine base shaft to realize the position adjustment of feed end and discharge end, achieve uniform wear, prolong the service life, and operate flexibly and conveniently. It has also been widely used in metallurgy, chemical industry and other industries.
The reversible sieve bend screen plate is a classification equipment for dehydration, demineralization and desliming of fine-grained materials used in the coal industry. It is mainly used in coal washing plants and is generally used in combination with heavy medium cyclone.
The sieve bend screen plate is mainly composed of sieve bend screen stainless steel screen surface, screen frame and support. There is a central rotating shaft in the middle of the screen frame. The screen frame can rotate 180 degrees with the central rotating shaft. The screen does not need to be disassembled to change the direction, so as to prolong the service life of the screen surface. The coal slurry moves along the sieve bend screen plate surface. When each screen bar is crossed, due to the impact between the liquid flow and the sharp corner on the side of the screen bar, the tension of water on the particle surface is damaged at the included angle of the screen bar. Therefore, some water and fine particles are cut down to become the material under the screen.
