The product yield appears to have increased appreciably. this is mainly an outcome of being able to use a 0.2 mm screen in the drain and rinse centrifuges (effective separation size of about 0.125mm) compared with the 0.25 mm apertures in the drain and rinse sieve bends (effective separation size greater than 0.2.
The sieving effect of the trommel screen is designed to meet the power and residence time required for waste separation. since there is a wrap between plastics and the like, it is not easy to fall through a general circular sieve hole, and the actually separated garbage has a smaller particle size than the mesh.
Therefore, magnetic separation was carried out for the removal of magnetic particles from fly ash. as seen in table 2, the fe2o3 content of the fly ash changes marginally with a decrease in particle size. since particle size range is relatively broad, the fly ash sample is divided into two.
Transport costs are massively reduced, or the coal is sold directly as a high quality product. the use of drum screens is very common in coal beneficiation. the disadvantage here, however, is that between 10 and 20% of the coal is lost in the screen overflow. this proportion can however be recovered using x-ray transmission.
