When the shaft rotates, eccentric motion is transmitted from the eccentric portions, through the two bearings, to the screen frame. The patented design of Dillon Vibrating Screens requires just two bearings instead of the four used in ordinary mechanical screens, resulting in simplicity of construction which cuts power cost in half for any ...
A vibrating screen ( 2 bearing design) has an eccentric shaft and 2 counter weights at the shaft ends. I would like to know what should be the amount of eccentricity on the shaft and how much should be the weights at the end...

Vibration is transmitted to the screen deck by the exciter (vibrator) assembly. The vibrator assembly comprises eccentric masses mounted on the exciter shaft. The shaft is supported on either two or four (depending on the capabilities of the bearing and housing design) vibration screen duty self-aligning double row spherical roller bearings.

Here is my problem…. We have vibration problem with a 5' x 12' double deck inclined screen (2" and 1" screen, limestone is the media) at our site. The screen has an eccentric shaft with only TWO bearings and also has two pie shaped counter weights at each end. The shaft has a …
W. Brian Rowe DSc, FIMechE, in Hydrostatic, Aerostatic and Hybrid Bearing Design, 2012. Inter-Recess Flow and Bridge Angle. For an eccentric shaft, each recess pressure is different, as illustrated in Figure 1.3.Differences in recess pressures cause circumferential flow from one recess to another. Circumferential flow reduces bearing load support and also reduces film stiffness, particularly ...
I am trying to design a support frame for a screen. I have its weight (aproximately 20 tons) but I have to take into account the forces due to rotating eccentric shaft, it rotates with 1000 rpm. considering the eccentric design, I have the radial force, (2 eccentric weights on the two ends of shaft 180 kg and the distance from its cent.of gra. to center of rotation is 154 mm) and shaft is also ...

Eccentric screening optimizes vibrating screens for handling heavy-duty applications, such as classifying and scalping. The eccentric shaft design forces the screen body to follow the shaft movement. While it travels upward, the counterbalance weights move in the opposite direction and create an equal force to that generated by the body.
The machine is engineered with a triple shaft designed to generate smooth eccentric forces. Stroke amplitude, speed and operating angle are adjustable depending on the application requirements. Controlling the travel speed of the material can fine tune the efficiency of the screening area and deliver improved product gradation.
1. Cause analysis of eccentric shaft fracture of Vibrating Screen. (1) According to industry data and user usage, the service life of eccentric shaft is generally 1-2 years. If the time is too long, the eccentric shaft may break due to fatigue failure due …
The screen is critical to your plant production and your profitability. The Simplicity® SM Series is a single shaft, two-bearing inclined screen designed for heavy-duty scalping, intermediate sizing as well as finished screening of virtually any material. And it delivers. The two bearing offering has a wide variety of models, sizes and
The F-Class features an advanced eccentric shaft design, supported by four high-performance, double spherical roller bearings. The double eccentric shaft creates a constant positive stroke that handle material volume spikes without losing momentum. As the eccentric shaft turns, the screen body is forced to follow the shaft movement.
