    To summarize the coal mill controls they may be divided basically into two major categories . 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel. Columbia Steel has earned a reputation for top service and quality replacement parts for EL coal pulverizers. Our state-of-the-art manufacturing facilities — combined with in-house production from pattern-making through finish machining — result in superior quality control. Our customers enjoy trouble-free operation and reduced downtime.

    Aug 29 2007 · We have 8 Raymond Bowl Mill pulverizer and have the same problem on only one of the mills. I have noticed that the foaming mill oil has to be changed more often than others due to increased oxidation (higher TAN). The oil moves up the vertical shaft via a groove on the vertical shaft. I believe this is called an akeli pump. today there normally exists a combustible coal/ air mixture in the burner lines and pulverizer equipment. Hence there is the continual danger of fires and under certain conditions explosions. Proper design and operation of the pulverized coal burners protects the pulverizing system
