“…The Khadsaliya Lignite Mines stand out due to the implementation of India's pioneering Dry Lignite Beneficiation Pyrite Separation Plant. This technical marvel is built upon the state-of-the-art RAMDARS technology [26][27][28] . This plant primarily serves to automatically separate pyrite from lignite, ensuring that only clean lignite is sent to the stockyard.…”

“…Low-grade bituminous coal, characterized by a low degree of metamorphism, tends to adhere and obstruct the screen's apertures due to the surface tension of external water [4,5]. Traditional vibrating screens, with their limited ejection intensity, often encounter issues such as blocked screen apertures and agglomeration of the screen's surface when dry-screening wet, fine, low-grade bituminous coal [6][7][8]. These challenges significantly impede the progress of the thermal coal preparation process [9,10].…”

Flip-flow vibrating screens (FFVSs) effectively tackle the challenges posed by the dry deep-screening of wet, fine, low-grade bituminous coal, thereby facilitating advancements in the thermal coal preparation process. The tensile lengths of the screen panels not only influence the service lives of the screen panels but also play a pivotal role in determining the screening performance of the FFVSs. To investigate the effect of the screen-panel tensile length on the screening performance of an FFVS, this study constructs a dual-mass flip-flow screening test rig. The experimental results reveal that when the fine-particle content and the external water content in the feed of low-grade bituminous coal are 55% and 16%, respectively, the most favorable tensile length of the screen panels is 2 mm. With a fine-particle content of 55% in the feed of low-grade bituminous coal and an increase in the external water content from 4% to 20%, the screening efficiency of the FFVS initially decreases and then increases. Notably, low-grade bituminous coal with 16% external water content poses the most challenging screening conditions. Furthermore, when the external water content of the low-grade bituminous coal is 16% and the fine-particle content in the feed increases from 25% to 55%, the screening efficiency of the FFVS gradually improves.
