Hourly output of the mixer cyclical:
where V – capacity of the drum (the cup) blender, l;
Kв – factor out the concrete mix, which is the ratio volume of the mixture obtained in one batch to the capacity of the drum (heavy concrete Kв = 0,67, for lightweight aggregate concrete – Kв = 0,75;
nз – number of mixtures at 1 hour.
