For an efficient coalscreening process, the kinetic properties of screen body should accord with the law of coalscreening principle. As we know, the blinding of apertures with nearmesh coal particles is inevitable in practice and can affect the other particles passing through the screen surface. For the traditional large vibrating screen ...

Evolution process and regulation of particle kinematics and spatial ...

One of the most widely used screening technologies for steam coal preparation after removal of fine fractions, is a 6 mm screening method. We propose a novel variableamplitude equalthickness elastic screen (VAETES) to solve the problem of material accumulation and screen aperture blockage during the 6 mm screening process of steam moist coal.

Evaluation of coal screening performance by spatial image ...

In the coal preparation process, evaluation of the screening performance involves the measurement of particle size distribution of products, which has traditionally been carried out using a manual screening method (SM), a relatively timeconsuming process that does not provide timely feedback for adjusting operational parameters.
