In addition to raising the coal temperature inside the mill for drying and better grinding, the same air works as the transport medium to move the pulverized coal out of the mill: it travels through the annular space between the fixed trunnion tubes and the rotating hot air tube onwards to the classifier.
Traditionally, ethanol from corn has primarily been produced through dry and wetmilling processes. The majority of ethanol production is from drygrind technology. The traditional drygrind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further.
How Corn is Processed to Make Ethanol. The process of making corn into ethanol is a multistep process. The first step is milling the corn. It can be done by dry milling or wet milling. Figures and show the process steps for each wet and dry milling.

GRAIN PROCESSING INDUSTRIES Three basic industries–milling (wheat and corn), feed manufacturing, and soybean processing—process wheat, corn, and soybeans. Milling Industries Milling is a process by which kernel components are separated physically or chemically. Each milling process yields products indicative of the grain being milled.
Coal dryer systems that dry only. Systems that dry and cool. Coal dryers that recirculate the cooling zone exhaust gas to the drying zone supply for improved efficiency. Coal drying systems with closedloop recirculated process gas streams that are heated with a directfired process gas heater.
In addition to the requirement by NFPA 85 for inerting a tripped mill system, coal mill OEMs usually recommend that a mill system be inerted during both the normal mill startup and shut down process. Steam is commonly employed in the power industry for coal pulverizer system inerting, due to its ready availability and cost effectiveness.

The wet process suffered the obvious disadvantage that, when the slurry was introduced into the kiln, a large amount of extra fuel was used in evaporating the water. Furthermore, a larger kiln was needed for a given clinker output, because much of the kiln''s length was used up for the drying process.
