The sintering machine is applicable for sintering operation in sintering plants of large iron & steel companies. It is main equipment in the ventilation sintering process, which can sinter concentrate powder and rich ore powder with different ingredients and different particle sizes into blocks and partially eliminate harmful substances such as sulfur and phosphorus contained in the mineral. The sintering machine can be divided into several specifications such as different lengths and different widths according to the sintering area, and is selected by customers according to its yield or site conditions. The larger its sintering area is, the higher its yield will be.
