Abstract

PURPOSE: Mineral oil-coal mix of low coal content is continuously pulverized by a wet method and the product is graded, then they are concentrated, thus permitting continuous and efficient production of coal oil mix of high stability and high quality.
CONSTITUTION: Coal and mineral oil are fed from pipes 3 and 4 through feeder 2 to wet-type continuous grinder 1 where the coal is pulverized. The content of coal in the grinder is kept lower than 30% of the total weight of the mixture. The resulting coal oil mix of relatively low viscosity is sent from the coal oil reciever through pump 10 and introduced into liquid cyclon 11 where a minor part of coal oil mix containing coarse coal particles of over 100 micron sizes is separated and returned through pipe 12 to feeder 2. Meanwhile, the part of coal oil mix containing fine particles of coal, less than 100 mecrons, is introduced through pipe 13 into thickener 14 where the part of thin mix is returned to feeder 2 and the thickened part is taken out of pipe 20 as the product.
