[0002] The sintering machine is suitable for the sintering operation of large-scale ferrous metallurgical sintering plants. It is the main equipment in the exhaust sintering process. It can sinter concentrate powder and rich ore powder of different components and different particle sizes into blocks, and partially eliminate harmful impurities such as sulfur and phosphorus contained in the ore. The sintering machine is divided into several specifications of different lengths and widths according to the sintering area. The larger the sintering area, the higher the output. In addition, during the sintering process, a flue gas treatment device is required to filter the flue gas generated during the sintering process to prevent the flue gas from polluting the air.
