Screening is one of the most important parts in aggregate production. It takes place before and/or after the crushing stage (or stages) and produces the specifications required of the final products. The purpose of screening is to separate a flow of aggregate particles into uniform sizes. This is accomplished by using Vibrating Screens.
For the clean and efficient utilization of coal, coal preparation is an important measure to solve the problem of air pollutant emissions, solid waste generation and save coal resources in the world [1, 2].Screening is the basic process for cleaning and efficient utilization of coal, and is mainly realized via vibrating screen [3].A conventional large …
The results showed that this screen surface could achieve elastic screening with variable vibration intensity, effectively overcome the moist material adhesion, and resolve the issue of material accumulation. The screening efficiency reached the maximum at 10.00 t·h −1 ·m −2 feeding speed. The impacts of screen body amplitude, frequency ...

Considering that the screening process is a stochastic process with stable properties (Peng et al., 2018), the time-domain average load on the screen mesh calculated in the screening process model is transformed to screen mesh fluctuating model as the external load. Therefore, the LVA of screen mesh caused by particle impact and …
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 …
