The high efficiency concentrator is not only a type of pure sedimentation equipment, but also a new type of dewatering equipment with the characteristic of mud settling filter. The high efficiency coal concentrator is mainly composed of the circular concentration tank and the rake scraping machine. The pulp particles are hanging in the concentration tank and gradually subside under the gravity action. So the upper part of the concentration tank turns into pure water, making the solid and the liquid separate. And the mud which deposits on the bottom of the concentration tank will be continuously scraping set to the throat in the center of the concentration tank bottom by the rake scraping machine. The clarified water will slop over along the top edge of the concentration tank.
The ore tube drier is a kind of drying equipment which uses the high-temperature and high-speed flue gas to dry the fine coal in a suspended state. The ore tube dryer is especially adapted to processing the fine materials with low density. Since the contact surface of the coal and hot flue gas in the dryer is large, the drying speed is fast. The advantages of the ore tube dryer has the advantages of small footprint, less investment in equipment and large unit volume of vaporized water, short residence time of the fine coal in the dryer, simple structure, easy manufacture, easy maintenance and low consumption of steel. The ore tube dryer has the disadvantages of low thermal efficiency, large power consumption, large attrition of tube wall and high drying cost. In addition, the drying plant is required to be built higher. The increased gray of the fine coal is large after drying. The control is complex and large amount of coal dust will be produced. Since the high-temperature flue gas has rapid heating effect on the wet fine coal, the coarse-grained coal will be unevenly heated so that it will be crushed. The ore tube dryer has crushing effect to some extent.
