1. A system comprising:
at least one transportation mechanism to transport blending components from a first tub to a second tub, the second tub to enable blending operations and to be located within the first tub, wherein the blending components are enabled to be moved to side areas of the first tub via the at least one transportation mechanism, and wherein the transport of the blending components to the second tub occurs through chutes that are provided between the first tub and the second tub in said side areas and that comprises the at least one transportation mechanism;
an electric motor and a control unit associated with the at least one transportation mechanism; and
at least one variable frequency drive (VFD) associated with the electric motor and the control unit, the at least one VFD to enable real-time control of a frequency or speed associated with the at least one transportation mechanism.
