We consider the collision of two particles having distinct rest masses and orbiting near a Kerr-MOG black hole, and we further determine the center-of-mass energy (i.e., CME) associated with the particles. It is found that the CME energy is influenced not only by the rotation parameter a, but also by the MOG parameter . Notably, it is shown that an extremal Kerr-MOG black hole case leads to surprisingly high the CME if and only if the parameter a satisfies the values given in the range
which diverges from that observed in Kerr-like black holes, thus highlighting the distinct characteristics of Kerr-MOG black holes. We present compelling evidence suggesting that Kerr-MOG black holes potentially act as significant generators for high-energy particles within the polar region.
