Dec 13, 2011· Ball tube mills are either pressurized or suction type. In the pressurized type, the hot primary air is used for drying the coal and to transport the milled coal to the furnace. In this type, leakage in the mill area is high.In the suction type, the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone.

The process out clinker is cooled and ground to a fine powder with the addition of about 3 to 5% of gypsum. The material produced by this process known as Portland cement. The cement manufacturing is done by majorly by two methods known as wet process and dry process depending on their mixing is done with water or without water.

Traditionally, ethanol from corn has primarily been produced through dry- and wet-milling processes. The majority of U.S. ethanol production is from dry-grind technology. The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further.
