[0002] Sintering machine is suitable for sintering operation in large-scale ferrous metallurgical sintering plants, mainly suitable for sintering treatment of iron ore powder in large and medium-sized sintering plants. It is the main equipment in the exhaust sintering process, which 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. Sintering machine is divided into several specifications of different lengths and widths according to the sintering area. Users can choose according to their output or site conditions. The larger the sintering area, the higher the output.

[0003] The CO emissions generated during the sintering process not only affect the environmental quality, but may also cause harm to human health. The distribution of materials on traditional sintering machines is usually completed by round rollers under the distribution bin, and the surface of the round rollers is prone to form hardening, resulting in uneven roller surface, poor material feeding, and uneven distribution of materials, resulting in uneven height of the mixed material layer on the sintering trolley surface, which leads to increased CO emissions after uneven sintering of the mixed material. To this end, we provide a device that can reduce the CO of sintering machines to solve the above problems. Utility Model Content
