YK Series Vibrating Screen,Mobile Screening Machine Manufacturer in China
The YK Series Vibrating Screen is mainly used for screening program processing coal preparation industry, because the trajectory and drive different types of ultrasonic vibrating screen, YK Series Vibrating Screen is a kind of derivative products of rotary vibration sieve. Action principle is through ultrasonic vibration wave attached on the screen of the (machine wave), the ultra fine powder by ultrasonic acceleration huge, thereby inhibiting the adhesion, friction, pancake, wedge blocking net factor, improving the screening efficiency and net cleaning efficiency.
Ultrasonic YK Series Vibrating Screen cleaning system, can be combined with various types of circular vibrating screen, the screen with high frequency ultrasonic vibration in low frequency vibration at the same time, the particles into a sieve suspended state, so as to avoid clogging the mesh.
The screen surface is the key essential components in the design of vibration sieve, sieve, sieve surface on the basic requirement is the machine strength, enough opening rate (total maximum aperture area and the screen surface area ratio), the mesh is not easy to be blocked. Common screen sieve grate, sieve, sieve, sieve and sieve cloth etc, detailed below the YK Series Vibrating Screen surface.
(1) screen grate
Sieve grate is a certain section shape by a parallel arrangement of a set of grate is directly fixed on the screen box beam formed on the screen surface, it is also known as the grate surface or the bar screen surface. Bar shape common are round, Bian Gang, T shaped steel, special steel, steel, steel inverted shape.
The sieve is a screen surface with A3, 16Mn, 16MnCr and other materials steel plate after drilling and punching processing method of production.YK Series Vibrating Screen,We are Mobile Screening Machine Manufacturer in China. The thickness of the lamina cribrosa is generally 5~12mm. The hole shape is usually round, individual cases with square, in order to make the plate has enough strength and open hole ratio as large as possible, circular meshes are almost always as a rhombus arrangement.
The screen is made by steel wire braided sieve, sieve generally square. The knitting method of different, can make a variety of screen structure. Common structure has simple structure, two kinds of square hole sieve. As Mobile Screening Machine Manufacturer in China,We have YK Series Vibrating Screen for sale.
The screen hole rate is high, up to 70%, but no sieve plate firmly, short life. In general, for fine-grained screening, in coal preparation plant commonly used in less than 13mm material screening.
Hole shaped sieve plate is almost rectangular, and larger length width ratio, commonly known as screen. In the coal preparation plant, sewn with several 0.25mm, 0.5mm and 0.75mm sieve, widely used for dehydration, desliming and medium screening. Welding sieve hole rate is about 25%, a sieve hole rate is about 14%.
(5) screen cloth
Screen cloth and mesh cloth, it has no fundamental difference with the screen, but also by the size, weft wire woven wire mesh, but are smaller and. In the coal preparation plant, commonly used screen cloth for slime or cleaned coal dewatering, classification, recycling, common specifications for the 40 mesh, perforated rate can reach 40%~50%.
