The Features And Working Priciple of High Frequency Screen

High frequency screen is widely used to screen (including dry and wet type), grade and dewater materials in beneficiation, coal separation, chemicals, bricks, food, pharmaceutical, caustic soda, fertilizers, paper and other industries. In fine classification process, screening efficiency can be up to 70% if given appropriate feeding concentration and feeding particle size (200 mesh content), and the difference between sieve particle size and feeding particle size is less than 30 percent.
High screening efficiency can significantly reduce the qualified gain content in cyclic loading and screening. high frequency screen has a strict control on the particle size of materials under screening so that it can eliminate the adverse effect on concentrate grade. In addition, the high-density small particles are easy to be settled on screening surface and can significantly improve the taste of materials.
High Frequency Screen Features:
1.high efficiency
2.small amplitude
3.high frequency of screening;
Working Principle:
It differs from the conventional screens with breaking of the surface tension of slurry and small granularity’s high speed vibration on sieve cover and accelerates the separating of large-density useful mines and increase the contacting probability of the materials smaller than output granularity and the sieve pore. Therefore produce good condition and make the materials smaller than the output granularity, especially the big-density materials and slurry get through the sieve pore together.
