On the basis of making full use of the original equipment shell, fans and equipment, the Bar Grate Cooler was transformed into stepping grate cooler, and the tail hammer crusher into roller crusher, reduced the transmission power. The heat recovery efficiency of grate cooler was increased from 71% to more than 75% after the renovation, which saved the renovation cost and achieved the goal of energy saving and consumption reduction.
