Des Screenex

Des. This provides the initial size separation for the larger and fine coal circuits. Water is applied to the material as it passes over the screen decking to assist the separation process. Material, which passes through the screen apertures, is collected in a single underpan mounted below the screen and then directed to the next stage ofget price

DESLIMING OF FINE COAL WHAT IS THE CORRECT CYCLONE?

Fine coal beneficiation via spirals is the most common process route in South Africa with des cyclones being used to deslime the fine coal before the spiral process. One would therefore assume that the performance of the des cyclones would be similar for these spiral operations but field data, as seen in Figure 1, indicates otherwise.get price

Des Cyclones 911metallurgist

Analysis of the feed to several plants revealed that the material finer than 44 µm (325 mesh) and even 70 µm (200 mesh) was usually very high in ash content (>30 %) with a considerable amount of superfine size clays. Due to the high ash content and the poor dewatering ability of the minus 44 µm coal when recovered, it became viable to consider completely discarding this size fraction.get price
