Detailed Product Description: | Semi-solids aqueous slurry of pulverized coal refers to the formation of the coal production process of a product, and, depending on the formation mechanism of different varieties, the nature of the difference is very large, you can use is also very different, there are roughly as follows Several types. A coking coal preparation plant flotation tailings such slime in a foreign country, is generally a waste of their nature or similar washing coal gangue. Coal vary with the quality of the flotation slime big difference, such as gas coal flotation process extraction rate Huainan only 30% to 40%, which is relatively low ash coal slurry, coal and washed coal quality in comparison close; Pingdingshan coal is 1/3 fat coal or coke, coal flotation extraction rate of 70% to 80%, flotation tailings to a higher ash, coal gangue and washing close. Depending on the slime recovery process, the physical properties of the slime of a larger difference. As with pressure filter slime, more uniform particle distribution, its viscosity, water holding capacity than the weak, help to reduce moisture. For example, a filter press Pingdingshan Coal Mine eight slime, almost half a year after piling up in the dry season, when the dust grab grabbed a total rate of close to 10% moisture content; the other is a slime tailings settling ponds or fields, according to the solid particles in water, natural sedimentation principle, to achieve solid-liquid separation and output of slime. This process has a particle size classification function, easy precipitation of coarse particles, mostly concentrated in the vicinity of the slime water inlet, fine particles in the middle position, the fine particles at the end. End of the slime has a high viscosity and high water holding capacity, similar to the glutinous rice group, thin and soft, dry months, the surface appears to have dry, internal moisture content almost did not fall, this slime is the most difficult. Two coal-water mixture, such as coal washery slime output of washing slime, after hydraulic transportation of coal output of slime, slime and some are better than this coal quality, quantity, often incorporated into the finished product came from coal . More than the number of doped out just a few, there may be a large number of high-quality output slime, in addition to properly handle, it will also have a negative impact on the economic benefits of the mine. 3 entrained slime mine drainage, waste dump water washed down the slime slime collected these are all dirty coal miscellaneous slime, which is characterized by a small number, inconsistent quality, but generally better than flotation tailings good quality. |
