failure of vibratory screen in coal screening

As we all know,sticky coalhas always been a problem in the coal screening industry, due to the characteristics of viscous coal, it is easy to adhere to the screen surface, or the mesh is blocked.Traditional drying,wet sieving and vertical sievingcannot solve these problems fundamentally.

Oct 01, 2017· A visual inspection approach was used to determine the percentage of failure (%) and the cumulative percentage of failures for each sub-components of the vibrating screen for a period of 6 years. The following formulae were used: (1) γ = i n × 100 Where γ the cumulative percentages of failure for each componentis, i is thecumulative frequency and n is the number of failure recorded over the period…
