subject: What Is The Much Better Way To Dry Materials? [print this page] The dryer is widely used in building materials, metallurgy, chemical industry, cement industry drying slag, limestone, coal, slag, clay and other materials. Mine dryer has a well-made, stable performance, advanced technology, high output, low power consumption, small footprint, high degree of mechanization. Is the indispensableequipment in your drying materials. In order to increase energy-saving drying system, how to improve the drying efficiency of the dryer, to achieve better drying effect. Drying line design, it is necessary to seek the rational allocation of the drying equipment; production lines have been completed, it should adopt new technologies to improve the matching of the drying line. The following are the two assumptions of the dryer energy saving.
1, reducing the particle size and to maintain both the amount of feed material particles finer logistics uniformity as possible, the smaller the hysteresis trends in the system; the other hand, the smaller the particle size, the greater the heating area, evaporation intensity higher. Pellet group contrast, easy to form a gas film and the hard layer to prevent heat and mass transfer of the inner material. In drying clay or shale, the material for crushing. Viscous water wet clay, and its fragmentation is a problem.
2, to improve the feeding way rotary drum dryer almost all oblique slip tube feeding. As the high furnace temperature, load changes, and slip tube heated flue gas erosion, oxidation, deformation damage is very serious, and replacement would be quite troublesome. Even more serious is, burn bending deformation of the slip tube oftenleveraging the roof or dryer to block the fire ring, resulting in air leakage for materials, a significant reduction in thermal efficiency and service life of the dryer. Whether slip tube used in the steel or cast iron pipe, are not a good solution to its short life. Order to extendthe life of the dryer feed tube, oblique slip tube changed to "pipe in the form of + slot board. On the straight tube, straight to assemble into the furnace wall, to avoid the high temperature oxidation and hot flue gas erosion; under paragraph oblique bad board, following a fall by the straight pipe materials, and then slipped into the drying materialincline machine. Chute board fire-resistant cast iron plate production, boosting the following the ascent of the firebrick. Transformation of the feeding tube should be in conjunction with the transformation of the hot stove and seals.
