Automatic control method of vertical material grinding system

The invention discloses an automatic control method of a vertical material grinding system. The automatic control method comprises the steps that S1, the working condition of a vertical grinding system is judged for the first time; s2, secondarily judging the working condition of the system; s21, whether the full milling working condition is true or not is judged according to the milling pressure difference, the currents of the powder concentrator and the circulating fan and the slag spitting amount value; s22, judging whether the auxiliary material breaking working condition is true or not according to the auxiliary material scale flow; s23, judging whether the high-moisture and high-magnesium working condition of the material is true or not according to the data of the online magnesium oxide analyzer and the self-developed moisture analyzer; s24, judging whether the working condition in rainy days is true or not according to a self-developed rainwater measuring instrument; s25, if the working conditions of
