High Frequency Screen Introduction:

High frequency screen has advantages of high efficiency, small amplitude and high screening frequency.It is an effective equipment for screening and classification of fine materials. It is widely used in screening or classification operations of iron ore, tin, tungsten, tantalum and niobium ore dressing plants. The purpose of high frequency screen is dehydration, it is hoped that a filter material layer will be formed on the screen surface as soon as possible in order to block the passage of fine coal and thus reduce the loss of solid materials in water. Improve the recovery rate of solid. If the amplitude of the screen surface is too large, the filter will be destroyed. Therefore, high frequency screen does not require large amplitudes. Under the condition of attainable vibration intensity, in order to increase the action times of slurry on the screen surface relative to the screen surface and improve the transport capacity of the screen surface, it is advisable to adopt a higher vibration frequency, that is, the advantageous motion characteristics of the wet screening machine should be high frequency and low amplitude. The high frequency sieve is precisely based on such a theoretical basis of the wet screening machine, its vibration frequency can reach more than 24 Hz, the amplitude is 1.0 ~ 2.5 mm.

Working Principle:

The vibration exciter drives the screen surface through the transmission mechanism for high frequency screen, and the screen box hold still. The vibration system is designed to work in the near resonance state, the whole machine is supported by vibration absorber, the ground is not subjected to dynamic load basically, and the sieve machine does not need to make the foundation, and can work normally directly installed on the solid flat ground or ordinary steel structure platform. The vibration frequency of the screen surface is 50 Hz, the amplitude is 0 ~ 2 mm, the vibration intensity is 810 times of the gravity acceleration, and the vibration intensity of the general mechanical vibrating screen is 2 ~ 3 times that of the general mechanical vibrating screen. Screen surface is not easy to block holes, screening efficiency is high, processing capacity is large.
