Embodiment Construction

[0012] The vibrating screen high-frequency screening method described in the embodiment of the present invention adopts a vibrator and a vibrating system. The vibrator drives the screen surface to vibrate at high frequency through a transmission mechanism. At this time, the screen box is still; The whole machine is supported by vibration damping, so that the ground basically does not bear dynamic load. The bottom of the screen machine needs to be made of high-strength spring foundation, which is directly installed on a solid and flat ground or an ordinary steel structure platform; the vibration frequency of the screen surface is 50- 100Hz, amplitude 0~2 mm, mechanical strength 8~10 times of the acceleration of gravity.

[0013] Further, when the vibration frequency of the screen surface is 50 Hz, the vibration amplitude is 0.5 mm, and an auxiliary shock-absorbing spring needs to be added for shock absorption at this time.

[0014] When the vibration frequency of the screen sur...

Abstract

The invention discloses a high-frequency screening method for a vibrating screen. A vibration exciter and a vibration system are adopted, the vibration exciter drives a screen surface to make high-frequency vibration through a transmission mechanism, and a screen box is static at the moment; the vibration system works in a near-resonance state, the whole machine is supported through vibration attenuation, so that the ground does not bear dynamic loads basically, the bottom of a screen machine needs a foundation made of high-strength springs, and the foundation is directly installed on the solid and smooth ground or a common steel structure platform; the vibration frequency of the screen surface of the screen machine ranges from 50 Hz to 100 Hz, the vibration amplitude ranges from 0 mm to 2 mm, and the mechanical strength is 8 times to 10 times of the gravitational acceleration. According to the high-frequency screening method for the vibrating screen, holes of the screen surface are not prone to being blocked, the screening efficiency is high, and the handling capacity is high.

Description

technical field [0001] The invention relates to a vibrating screen high-frequency screening method, which belongs to the field of mining machinery equipment and is used for crushing river pebbles and other gravel into sand. Background technique [0002] Vibrating screens are commonly used mechanical equipment in mining machinery. At present, in the high-frequency screening process for vibrating screens, the particle size in the screening process is often large due to the process links, and the loss of the vibrating screen is serious, especially when the particle size is large. The pressure of the vibrating screen is also greatly increased, so the screening effect of the vibrating screen is further reduced. Therefore, it is necessary to carry out high-frequency screening for the pressure-bearing capacity and particle size of the vibrating screen. The present invention is designed for this technical problem. Vibrating screen high-frequency screening method. [0003] Content...
