A NOVEL AND IMPROVED METHOD OF PRODUCING SOLID-LIQUID MIXTURES WITH A HIGH CONCENTRATION OF SOLIDS

摘要

The invention relates to a novel and improved method of producing suspensions of solids through liquids, and more particularly, of high-concentration coal in water, which comprises conventional pre-crushing of the coal, followed by riddling the pre-crushed to the maximum particle size sought for the end suspension. The pre-crushing operation is performed such that the coarse fraction from said riddling step can account for up to 90% by weight of the overall pre-crushed. That coarse fraction is then passed to wet milling, and the resulting produce of the milling admixed to the fine fraction from the riddling step.
