Description of High Frequency Screen

High frequency screen consists of vibration exciter, ore pulp distributor, screen frame, machine frame, suspension springs and sieve, etc.

High efficiency, small amplitude and high frequency of screening; it differs from the conventional screens with breaking of the surface tension of pulp and small granularity 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 pulp get through the sieve pore together.

Working principle of High Frequency Screen

High frequency vibrating screene difers from the conventional screen with breaking of the surface tension of slurry and small grnularity'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 it can produce good conditions and make the materials smaller than the output granularity, especially the big-density materials and slurr get through the sieve pore together.

Application of High Frequency Screen

High frequency screens have become more standardized and widely adopted in materials classification processes. It allows efficient cuts and fine separations, which can provide high purity and precise sizing control of the product (for sizes of fine particles up to 0.074-1.5mm).[1] Common industrial applications include dewatering of materials, processing of powder in coal, metallurgy, ores and minerals, wood pelleting, fractionated reclaimed asphalt pavement, food, pharmaceutical and chemical industry. Fineness of the products and system capacities varies over a huge range between different models, to satisfy individual application requirements.

Features of High Frequency Screen

1.Using laminated mesh increases monolayer aperture, which not only increases the useful life of the screen, but also can prevent jamming and wearing.2 The rubber spring of high frequency screen supports the screen frame, which can reduce noise and set vibrating.3. It is low amplitude, which makes for the classification of fine and heavy materials.4. High frequency screen (high quality screen) is high efficiency, small amplitude, high screening frequency.
