High frequency screen is short for high frequency vibrating screen. As the name suggests, high frequency vibrating screen is the equipment which uses high vibration frequency to screen materials.
The high frequency vibrating screen is referred to as a high-frequency screen, which is composed of a vibration exciter, a slurry distributor, a screen frame, a frame, a suspension spring, and a screen. It is widely used in mineral processing, coal preparation, chemistry, brick making, food, pharmaceutics, alkali, fertilizer, paper, and other industries.
A High Frequency Screen is a specialized screening machine that operates at high vibration frequencies (typically 1500 to 4000 RPM) to classify fine-grained materials.
While a standard screen shakes the whole frame to move rocks, a High Frequency Vibrating Screen often applies vibration directly to the screen mesh or uses a high-speed exciter on a fixed frame. The key difference is the intensity. The high frequency breaks down the surface tension of the water in the mineral slurry.
This “breaking” action is crucial. Without it, fine particles stick together like mud. With it, the material stratifies. Coarse particles float to the top, and fine particles (valuable concentrate) pass through the mesh.
Separating large rocks is easy; gravity does the work. Separating microscopic dust in water is hard.
Surface Tension is the Enemy:In a wet slurry, water acts like glue. It holds coarse and fine particles together. If you use a normal low-frequency screen, the slurry just rides over the mesh like a waterslide. Nothing separates.
The Frequency Solution:By vibrating at 3000 RPM or higher, the High Frequency Screen acts like a sonic cleaner. It destroys the water tension. Imagine shaking a bottle of sand and water violently; the sand separates from the water.
The applications go beyond just “screening.” This machine acts as a filter, a grader, and a dewaterer.
Iron ore, tin, tungsten, tantalum, niobium sand and other concentrator screening or grading operations, also suitable for mineral processing, coal processing, chemical industry, brick making, food, pharmaceutical, alkali production, chemical fertilizer, paper making and other industries.
High frequency screen consists of vibration exciter, ore pulp distributor, screen frame, machine frame, suspension springs and sieve, etc. This series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.
High frequency vibrating mesh screen consists of base, frame, support, angle adjustment bar and electronic control box,etc.When the machine operates, the low frequency electromagnetic vibrator vibrates the feeder and outputs part of the mesh screen directly to move the whole screen. At the same time, the high frequency electromagnetic vibrator shakes the middle of mesh screen through the rubber cushion. The mesh screen is composed of three stainless steel screen layers; the lowest screen layer is high strength primary screen; the other two layers are workable screen in mine processing.

A High Frequency Screen is a vibratory screen used for fine particle separation, typically operating at frequencies between 1500-3600 RPM.
High Frequency Screens use rapid vibrations to stratify and separate fine particles through a screen mesh, allowing undersize material to pass through.
High Frequency Screens offer high screening efficiency, increased capacity for fine materials, and reduced blinding compared to conventional screens.
High Frequency Screens are used for processing minerals, coal, sand, and other materials requiring fine particle separation in dry or wet applications.
Consider feed rate, particle size distribution, screen mesh size, vibration frequency, and material moisture content when selecting a High Frequency Screen.
