Emissions of PM from all welding is based on 45,000 pounds of weld wire consumed per year and an emission factor of 12.2 pounds of fume per 1,000 pounds of weld wire consumed which is taken from AP-42 Table 12.19-1 (1/95) and assumed as a worst-case factor. Thus yields 0.27 tons per year of fume. All welding fume is considered to be PM 10

Dry milling (Fig. 7.1) involves grinding the incoming grain, then processing it through a series of steps to liquefy the flour and generate fermentable sugars.Amylases are added at two points in the process—the initial slurry step, and the liquefaction step, which follows a jet cooking operation that uses high-temperature steam to swell the starch.

Impact grinding is most efficient with dry, low-fat ingredients, although many other materials may be reduced in size by proper screen selection and regulated intake. Most hammermills have a horizontal drive shaft which suspends vertical hammers but for some ingredients, such as dried animal byproducts, a "vertical" hammermill is more efficient.
