It is used in vibrating grizzly feeders and screens to generate linear vibratory motion for material separation and feeding. The assembly converts rotational motion into controlled vibration.
Key parameters include shaft diameter, overall length, eccentricity, rated speed, dynamic balance grade, surface roughness, hardness, material grade, operating temperature, and weight. These must match the machine frame and application requirements.
A higher balance grade (e.g., G2.5) reduces vibration and noise compared to a lower grade (e.g., G6.3). It ensures smoother operation and longer bearing life.
Increased vibration noise, elevated bearing temperature, or visible wear on the shaft are signs of potential issues. Regular inspection and lubrication are recommended.
