The nozzle static ring 22MG23.11.08J.04 for coal mill is an important component in the medium-speed coal mill. Its main function is to cooperate with the dynamic ring to form the nozzle ring to achieve effective guidance and distribution of the primary hot air. The nozzle ring consists of a dynamic ring and a static ring, and the static ring is fixed on the middle frame of the mill. The design of the static ring usually includes two parts, the upper part and the lower part. The upper part is enlarged and extends inward to the throat position of the nozzle ring. This design helps to optimize the distribution of airflow and improve the drying and grinding efficiency of the coal mill. The nozzle static ring 22MG23.11.08J.04 plays a key role in the operation of the coal mill. It converts the static pressure of the primary hot air into dynamic pressure through the gap between it and the dynamic ring, thereby forming a high-speed airflow, drying the ground coal powder mixture and conveying it to the separator at the top of the coal mill. In addition, the static ring also has certain wear resistance and is usually made of high wear-resistant materials to adapt to the harsh working environment inside the coal mill. In actual applications, the wear of the static ring will affect the performance of the coal mill, so regular inspection and maintenance are required to ensure its normal operation. |
