High-frequency sieve operation using high-frequency vibration machine, the resulting vibration frequency is high, and its rotational speed is up to 1500-7200r/min, which can accelerate the separation of materials on the screen surface, relative to the dewatering sieve screening efficiency is higher, can be as high as 70% or more. High-frequency sieve screen surface utilisation is also very high, large capacity, and will not occur plugging phenomenon.
Dewatering screen is mainly containing cement slurry in the material for dry discharge, slag and water separation, to achieve the purpose of dry discharge, dry discharge of the sieve on the general requirements of the more the better; and high frequency sieve is a different particle size materials for grading and screening, including wet and dry sieve, sieve on the sieve and sieve under the ratio of the material depends on the material itself.
High-frequency sieve can easily destroy the tension of the material surface, and accelerate the fine-grained materials in the screen surface high-speed oscillation, thus accelerating the separation of large density materials, a substantial increase in the material smaller than the screen holes and the contact rate of the screen holes, to create good separation conditions, so that the specific gravity of the material quickly sieve separation; dewatering sieve adopts double-electrode synchronous technology, through the tape coupling to drive the two unconnected vibrators for the synchronous reversed The dewatering screen adopts double-electrode self-synchronous technology, through the belt coupling shaft respectively drive two mutually unrelated vibrators to make synchronous reverse operation, so that the sieve body makes cyclic reciprocating motion along the straight line direction, so as to achieve the purpose of classification and dehydration.
Dewatering screen machine structure is reasonable, high processing precision, durable, good dewatering effect, can be used alone, can also be used with the sand washing machine; while the high frequency screen adopts the design principle of high vibration, low amplitude, more conducive to the separation of fine, heavy materials through the screen, so the dewatering effect is better.
In summary, fully understand the difference between high frequency vibrating screen and dewatering screen, can be more convenient for future selection.
