MCTwin
Introduction
MCTwin is a software configuration of a double station MCBalance. One of the two units is adding regrind to
the process, the other unit is adding the master batch (color) to the process. There are two available control
modes for the MCTwin software, closed loop and open loop. In closed loop mode, the regrind is fed directly
from the grinder to the dosing system, the dosed amount of colorant is automatically adjusted to the
availability of regrind. In open loop mode, the regrind fed to the dosing system from a big regrind storage
tank, assuming there is more than enough regrind available.
