Each mixer truck concrete pump with the number of required calculations

When the concrete pump continuous operation, each equipped with the required concrete pump steel cement silo number of units, can be calculated as follows:
N = (Q1 / V) * (L / S + Tt)
Asphalt Mixing Plant of concrete mixer truck Taiwan (Taiwan);
Q1 an actual average of each concrete pump output volume (m / h);
V-Each concrete mixer truck capacity (m);
S-Concrete mixer truck average traffic speed (km / h);
L a concrete mixer truck round trip distance (km);
Each concrete mixer truck Tt a total stop time (h).
