than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size and dried to a greater extent.
The heart of a pulverized coal-fired boiler is the pulverizer, also known as the mill. Depending on speed pulverizers are classified as low-speed, medium-speed, and high-speed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace.
In this mill the coal passes between the rotating elements again and again until it has been pulverized to desired degree of fineness. The coal is crushed between two moving surfaces, namely, balls and races.
Coal dust feeding. Pulverised coal feeding is a critical process equipment that requires accuracy, quality and maximum reliability for continuous production. The parameters are based on the interplay of overall system engineering, material discharge, feeding and pneumatic material transport. Optimal pulverised coal feeding in three steps.
The mill and the pulverized fuel chute, which are exposed to the aforementioned atmosphere more frequently with biomass than coal, are equipped with an explosion suppression system (consisting of a container filled with fire extinguishing media, pressure sensors, etc.) in the case of unexpected dust explosions.
Powder Mill Pulverizer Our pulverizer or literally, powder grinder, is designed for SPVC (soft PVC, plasticized PVC), HDPE, LDPE, PP, ABS, EVA, PPR, PA and rubber. If 20-30% ground powder is added in production, the physical and chemical performances of final products will remain similar to virgin raw materials.
