A typical grinder of 45 Mg/hr (50 ton/hr) capacity will discharge about 1.6 to 2.5 dry normal m3/sec (3,500 to 5,500 dscfm) of air containing 1.14 to 11.4 g/dry normal m3 (0.5 to 5.0 gr/dscf) of PM. The air discharged is "tramp air," which infiltrates the circulating streams.
Apr 10, 2014· Abstract. Light intensity affects photosynthetic carbon (C) fixation and the supply of carbon to roots. To evaluate interactions between carbon supply and phosphorus (P) supply, effects of light intensity on sucrose accumulation, root growth, cluster root formation, carboxylate exudation, and P uptake capacity were studied in white lupin (Lupinus albus L.) grown …
Concerns have arisen about phosphorus use, however. Most of the phosphorus is wasted on its journey from mining to being eaten by humans, and the wasted phosphorus ends up in waterways where it can cause algal blooms. Another concern is that increased phosphorus usage will deplete the nonrenewable supply of phosphate rock.
