High Frequency Screen is superior for high efficiency, small amplitude, and high screening frequency. It is effective screening equipment for fine material, widely used for screening of iron ore, tin, tungsten, tantalum and niobium sand in dressing plant. Therefore, it is also called high frequency mineral screen, high frequency ore screen or mineral high frequency screen.
The Structure of High Frequency Screen
High frequency screen is composed of vibrator, pulp distributor, screen frame, rack, suspension spring and mesh.

Working Principle of High Frequency Mineral Screen
The high frequency can destroy the tensile force on the pulp surface and prevent high speed oscillation of fine material on the screening surface, enhancing separation effect of high density (ratio) useful minerals and increasing the contact probability of material less fine and the mesh. The better separation condition makes material less than separation size, especially material with high ratio, and pulp permeates through the mesh to become finished product.

The Features of High Frequency Screen
1.Acting as a new type efficient vibrating screen, it adopts the latest design.
2.The exciter vibrates through the motor driving the screen surface while the screen box is static.
3.No blocking of screen surface, high screening efficiency, processing capacity, especially suitable for fine material screening.
4. Screen surface consists of three layers of soft meshes with the first layer directly contacting with the material, forming working mesh and the bottom mesh used for dispersion force and vibration transmission to prolong the service life of the machine.
