摘要： A method for preparing ultra-low ash coal-water slurry includes: (A) grinding of coal to a size below the upper size limit and then making a proper concentration slurry; (B) screening coal by using the slurry particle separation device and separating them by density into tailings, middlings and clean coal, adjusting the fraction of clean coal production according to the ash content standard of final product and then producing the clean coal slurry and tailings slurry; (C) wet grinding of the middlings in step B; (D) reprocessing the product in step C by step B. The upper size limit can be 0.2 mm, 0.01 mm or 0.001 mm, and the ash content can be below 2%, 1% or 0.5%. This method can largely enhance the production rate of clean coal, improve the coal-water slurry fuel's particle size graduation, improve the fluidity and increase the particle concentration of the coal-water slurry fuel.

摘要： This invention relates to a centrifugal jig comprising a rotating device, at least one jig unit and a product receiver. The jig unit includes a hutch chamber, a screen residue chamber, a screen, a feeding device, a discharging device and a pulsator. The jig unit is installed on the rotor at an inclined angle along the movement of the feed. It is used to separate particles of different density in the slurry. The product receiver is fixed on the ground to collect the separated materials discharged from the rotating jig unit. Separated materials are discharged from an outlet of the screen residue chamber in the jig unit. This invention can unselectively separate any size particles of different density in the fine slurry.
