Double-roller press parallel grinding system

The invention discloses a double-roller press parallel grinding system which comprises two parallel roller press grinding systems, wherein each roller press grinding system comprises a roller press, a delivery pipeline, a classifying screener and a receiving system; a discharge hole of each roller press is connected with a feed inlet of each classifying screener by each delivery pipeline; two discharge holes are formed in each classifying screener; one discharge hole is communicated with a feed inlet of each roller press; and the other discharge hole is communicated with each receiving system. The double-roller press parallel grinding system is simple in process flow, convenient and reliable to operate, diversified in production mode, and flexible to allocate, makes full use of the characteristics of energy saving and consumption reduction of the roller press grinding systems, and completes crushing and grinding of materials, and the power consumption of the grinding system is reduced.
