The high-frequency screen is also called a high frequency vibrating screen. High-frequency vibrating screens are the most important screening machines primarily utilised in the mineral processing industry. The material is sieved or classified according to the particle size.
High frequency vibrating screen are widely used for screening or grading iron ore, gold ore, copper ore, and silica sand. It is especially suitable for the screening of fine-grained powder materials. The graded particle size is 0.074~1mm; the fineness is up to 300 mesh.
Adopting the new principle design, it is a new type of high-efficiency vibrating screening machine with a screening efficiency of over 70%, small amplitude, and high screening frequency. Different from the principle of general screening equipment, the high-frequency screen uses high frequency and it can destroy the tension of the slurry surface and the high-speed oscillation of the fine material on the sieve surface, accelerate the separation of large-density useful minerals, and increase the probability of separating the material in a smaller particle size.
The high-frequency screen is not easy to block the hole, and the processing capacity and solid recovery rate are high.
The vibration intensity is 2 to 3 times the vibration intensity of a general mechanical vibrating screen. The working noise of the whole machine is below 85dB(A).
Low failure rate, long lifetime and low maintenance costs
The excitation or amplitude of the sieve body can be adjusted to control the particle size.

Trommel Screen
A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries, and also be used for separation and screening of sand and stone in the sandstone field It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end.

Spiral Classifier
In mineral processing, the spiral classifier is widely used in the ore dressing plant to divert the ore, or to be used in the gravity ore dressing plant to classify the ore and fine mud, the slurry in the metal beneficiation process, and to remove mud and dewater in the washing operation.
