The analysis showed modal vibration patterns on the sides and feed box were the main contributors to noise. In Figure 1, one can see and verify the shape of the vibratory motion: circular (A), elliptical (B) or even linear (C). Vibration analysis technology gathers data on a screen box by measuring parameters such as g-force, stroke, rpm, orbit - and even lateral movement. By implementing a routine based measurement schedule you can develop an understanding for your vibrating screen and detect potential errors before they create a massive breakdown. A very erratic motion is developed when this wheel is rotated. A vibrating screen, just as many other similar equipment, is designed to move in a specific pattern. If the exciter starts again under heavy load, it is very easy to cause damage to the universal coupling and other parts of the exciter. INTRODUCTION Vibrating screens are used to screen the material to different sizes with the help of the screen the material that are crushed are categorized into various as per the requirement, and then sent to further processes. The rheological mechanical model of damping force was analyzed based on the Bingham model, and a magnetic circuit was designed according to electromagnetic theory. Rocky DEM is able to simulate accurate, polyhedral convex and concave particle shapes. deflection shape (ODS) analysis was used to examine the screen behavior under actual operating conditions.

All Products. Figure 1. Therefore, we designed a novel vibration isolator based on a magnetorheological damper, aiming to improve the vibration isolation performance of the vibrating screen. The equipment adopts advanced design means such as finite element analysis and anti-fatigue analysis to ensure the reasonable structure, low energy . The ideal height is four times the screen aperture. Vibration analysis is a process that monitors vibration levels and investigates the patterns in vibration signals. On the other, it pursues the ideal screening performance by optimizing the parameters of the screen in a way that particles find as many opportunities as possible to pass screen openings. The improved equipment has better working performance. First, the equipment does not occupy space, it is convenient to move, simple to operate, and easy to maintain, which saves time and space for . Harmonic loads relates to the vibration isolation of the vibrating screen, transient loads may arise subjected to impact and impulse, while the periodic loads and random loads often used to describe wave motions which occur at random intervals. These systems measure and transmit real-time vibration data such as acceleration, orbit, deviations and more. Abstract Vibration Analysis (VA) is a key technique used for maintenance and fault detec tion of vibrating machinery. An orbit plot analysis uses multi-directional vibration data to visualize the trajectory of the machine in question, and provides the user with important information regarding the operating status of the screen.
