Modeling and Dynamic Simulation of a Multi-slope Vibrating Screen
Usually, multi-slope vibrating screens use an unbalanced exciter to produce a circulating radial force of the same frequency on both drive shafts. This In the excitation device, the eccentric block moves at the same speed in the opposite direction, forming a linear force perpendicular to the center line of the two Collaborative optimization of linear vibrating screen

Collaborative optimization of linear vibrating screen
As shown in Fig. 4, the vibrating screen model uses dampers to simulate support springs, the exciter and eccentric mass are replaced by mass points. The structure size of the overall vibrating screen model is consistent with the original vibrating screen, and the relative coordinates of the centroid are the same as the original model.The vibrating screen exciter is a component of the screen that generates the vibrational motion to facilitate the screening process. It is a device that creates the vibrational force necessary to produce the required Vibrating screen exciter Haiside

Investigation for synchronization characteristics of
The double eccentric cam self-synchronous vibrating screen is mainly composed of cams, camshafts, cam grooves, screen frame and so on, as shown in Fig. 1. The two motors arequality of the vibrating screen. Vibrating screen: the source of vibration is the centrifugal force generated by the rotation of a group of eccentric blocks, thus driving the vibration of the screen box supported by two groups of springs. In the screen box, the particles of more than 80 mm are removed from the screen plate supported by threeJournal of Physics: Conference Series PAPER OPEN

Vibrating Screen Eccentric Shaft Fracture Cause?
The bearing shaft diameter belongs to the stress concentration position. Because the vibrating screen shaft is an eccentric shaft, so in its original processing process, located in the offset connection part of the two axes, will occupy the diameter and step, and the resulting phenomenon of stress concentration. 2, triangle belt tension is tooThe vibrating screen is not placed on the same level, the screen surface is inclined. Vibrating screen troubleshooting: Check whether the phase angles of the eccentric blocks of the vibrating screen on both sides of the same shaft are the same. The reasons for the small amplitude of the vibrating screen are as follows: Low power supply voltage;Common faults and troubleshooting of linear vibrating screen
