Input RPM divided by gear box ratio x diameter of head pulley x .2618= slat speed in Feet Per Minute. EXAMPLE: 8 divided by 14 = .571 x 1755 = 1002.86 input rpm div. 25.13 gbr = 39.91 head shaft rpm 39.91 x 9 = 359.19 x .2618 = 94.04 FPM. . ASPHALT OIL. To Find Asphalt % By Total Mix:
Dec 28, 2000 · Useful asphalt plant formulas. Production rate 1) A plant loses about 3% of its production rate per 1,000 ft of elevation, due to the thinning of the air. 2) Plants are designed to remove 5% moisture. The higher the moisture, the lower the production rate.
Asphalt Tonnage Calculator. Asphalt is a black cementitious material, made by fractional distillation of crude petroleum. This online Asphalt Volume Calculator helps you to estimate the Asphalt tonnage required for making a pavement of a specified length, width and thickness.
For example, to estimate TOC emissions from drum mix plant load-out operations using an asphalt loss-on-heating of 0.41 percent and temperature of 290°F, the following calculation is made: EF = 0.0172(-V)e((0.0251)(290 + 460) - 20.43) = 0.0172(-(-0.41))e((0.0251)(290 + 460) - 20.43) = 0.0172(0.41)e(-1.605)
