    Aug 01, 2018 The technology of mechanochemical oxidation of brown coal was developed using an AGO-2 laboratory planetary ball mill with water cooling, steel cylinders and balls with total mass of 200 g. A mixture of coal and oxidative reagent (10 g) was subjected to mechanochemical treatment in the ball mill at a calculated initial acceleration 200 m/s 2 of

    3 and Figure 6 illustrate the ground coal particle size by water jet mill and ball mill respectively. Calculation was made by the output of less than 11.55 m coal fines. The results show that the output per hour for the water jet mill is much higher than that of the ball mill, and the power consumption much lower than that of the latter

    Jan 01, 1991 A Workworth coal and Cerreon coal were pulverized by means of a wet ball mill. A Cerrej n coal was deashed. The results of proximate analysis are shown in Table 1.The dispersant, PSS (polystylene sulfonic acid, molecular weight; M≃10 5) was added for the reduction of viscosity of a CWM.In addition to the dispersing additive, a polyacrylic acid (PSA, M≃:2.8xl0 4) was added to

    Ability of surfactants to form highly loaded coal-water

    Mar 14, 2014 Coal tends to aggregate in water. In a coal-water mixture (CWM), the higher the coal content is, the more thickened the mixture is. To highly load a CWM with coal, therefore, it is necessary to use a dispersant. The authors synthesized new types of multibranched high molecular nonionic surfactants that did not contain any alkali metal which would be harmfuls in combustion. Those
