Solid–liquid separation technologies for coal

This chapter discusses current developments and latest applied solid–liquid separation technologies and equipment used for coal. It commences with a classification of the different solid–liquid separation technologies used and pre-treatment applied, such as thickening, coagulation and flocculation. It then describes all types of commonly used filters, including vacuum and pressure types, centrifuges such as vibrating basket, screen scroll, screen bowl and solid bowl types with their applications for different coal size fraction or coal tailings. An overview of non-mechanical technologies such as coal drying is given before the chapter closes with a discussion on the emerging and future trends in solid–liquid separation within the coal industry.
