Fine sand coarse sand vibration screening machine. YK series circular vibrating screen can screen out various specifications of sand. The rocks suitable for sand making, such as river pebbles, limestone and granite, go through the crusher and then enter the circular vibrating screen to screen out fine sand (sand with an average particle size of 0.25mm~0.125mm), …
The vibration speed, stroke, and angle are critical indicators of the current performance of vibrating equipment. When vibrating equipment is operating correctly, these do not change on their own. A random change in one of these …
Orbit Analysis On Vibrating Screens Vibration data is collected at each corner of the screen. Each corner is designated by either Feed (F) or Discharge (D) and Left (L) or (R) . So then FL would be Feed Left, etc. The vibration data also tells us the speed of the screen. Notice in the top right hand corner of this spectrum we see the RPM = 998.
Dual vibration from a single drive is the unique feature of the bivi-TEC® Screen. Two weights, vibrating at the same frequency, move relative to each other which tensions and relaxes the screen mats. The linear momentum of both vibrating movements is adjustable, resulting in open screen surfaces and optimal screening performance.
Let's examine a few concepts related to amplitude: The amplitude of vibration does not depend on the rotation of the vibrating mechanisms. Amplitude combined with rotation imparts a certain amount of acceleration to the …
