DRY CORN MILLING The .grain unloading, handling, and cleaning operations are similar to those in other grain mills but the subsequent operations are somewhat different (Reference 2, p. 216). Very little emission factor data were available for dry corn milling, except for some controlled emission factors tabulated in Reference 2 (pp. 222, 223).

The District has not prepared default emission calculation procedures for machining, grinding and sanding equipment. Emissions are typically calculated based on a material balance on the amount of material being processed. To obtain assistance identifying a procedure or emission factors for calculating emissions, contact the District.

Section 4 presents the preferred methods which differ depending on the process and pollutant for which an estimate is to be made. Section 5 presents the alternative methods. Quality assurance
Wet grinding was similar to dry grinding, the carborundum paper on the base and glass slide were soaked in distilled water and few drops of water were added after every 1020 s during grinding. Wet grinding started with a paper grade of 180 cc and shifted to 220 and 240 cc after 34 min. Fig. 2.11 shows the steps of dipping carborundum base ...
An emission factor relates the quantity (weight) of pollutants emitted to a unit of activity of the source. The uses for the emission factors reported in AP-42 include 1. Estimates of areawide emissions 2. Estimates of emissions for a specific facility and 3. Evaluation of emissions relative to ambient air quality.

Emission factor . for truck loading was not determined but is not expected to be significantly different. d/ Emission factor of 1.40 Ib/ton is based on tunnel belt emission factor of 1.40 determined in the Kansas City elevator study (Table 8).i/- e_l Emission factor of 1.05 Ib/ton for drying was based on dryer emissions, discussed in Appendix A, of 0.3 Ib/ton for column dryers
anthracite coal burned were five percent (5%), then the PM10 emission factor would become 2.3 x 5, or 11.5 pounds, of PM10 emitted per ton of anthracite coal burned (before control). 2. An S accompanying an emission factor means that this factor is the weighted average sulfur content of the fuel burned, expressed as a percent. See, for example,
The use of emission factors is well documented and typically use of such factors is straight forward. The introduction of US EPA AP-42 emission factors provided a limited range of usable emission factors. Presently, US EPA AP-42 and other emission factors exist for the processes listed in Table 1 through 4.
