Spring Failure Analysis of Mining Vibrating
Spring failure is one of the critical causes of the structural damage and low screening efficiency of mining vibrating screens. Therefore, spring failure diagnosis is necessary to prompt maintenance for the safety and Speaking of the vibrating screenperhaps for us ordinary people may have some strange,,but for the people in the coal industry, is again familiar with the necessary tools. Vibrating screen is an important equipment widely used in coal, metallurgy, port, water conservancy and electric power industry to complete various technological processes.Present Situation and Development of Vibrating Screen

At the start of the project, theThe condition-based maintenance of vibrating screens requires new methods of their elements’ diagnostics due to severe disturbances in measured signals from vibrators and falling pieces of material. The bolted joints of the sieving deck, when failed, require a lot of time and workforce for repair. In this research, the authors proposed the Diagnostics of Bolted Joints in Vibrating Screens Based on a

Vibrating screens are widely used to separate the material particles of different sizes in the ore mining and processing industry [].The vibrating screen plays an important role in realizing rational utilization of coal resources, protecting the environment and creating economic benefits for coal enterprises.Vibrating screens represent an effective particle separation equipment for coal cleaning. During the screening process, critical particles block the screen holes, and affect the screening performance. Therefore, a vibrating screen with a higher inclination angle and larger screen pore has been proposed to prevent plugging of the screen surface.Multiple parameter collaborative optimization of a particle

Multiple parameter collaborative optimization of a particle
The screening theory is central to the development of vibrating screens, and virtual screening tests provide an efficient way to carry out theoretical research on screening, which has the advantages of being cost-effective and more efficient [9].The discrete element method (DEM), which was proposed by Cundall and Strack [10], is a numerical method Flip-flow vibrating screens (FFVSs) are the critical screening equipment for classifying and dewatering wet materials in mining processing industry. During the screening process, the FFVSs can be regarded as a complex rigid-flexible coupled multi-body system where the screening operation and the dynamics of two screen frames interact.Stability analysis of the screening process of a vibrating flip
