【Abstract】 Recovery of fine coal slime is an indispensable key process link in a hydromine. The processes in current use suffer from the drawbacks of being complicated in process links and high in initial and operating costs. A brief introduction is made of the laboratory drag flight dewatering screen operating under simulated underground condition for fine slime recovery by way of bed filtration. What follows then is a discussion of the operation mechanism and the relationship between the filtration parameters involved.更多还原
