The invention discloses a clean-type two-jaw breaking grinding machine and a control system thereof. The clean-type two-jaw breaking grinding machine comprises a breaking stationary jaw, a first breaking movable jaw, a first breaking flywheel, a breaking motor, a second breaking movable jaw, a second breaking flywheel, a first grinding motor, a first grinding main shaft, a first grinding disc, a second grinding motor, a second grinding main shaft, a second grinding disc, a rack, a breaking discharge channel, a grinding discharge channel, a discharge hopper, a dust hopper, an air pump and a dust collecting box; and the control system consists of a raw material detection module, a material grinding detection module, a flow detection module, a PLC, a first grinding motor driving module, a second grinding motor driving module and a contactor. The clean-type two-jaw breaking grinding machine can achieve primary breaking, secondary breaking and grinding on a raw material, so that the degreeof size reduction of the raw material is raised, and the breaking time is shortened; and the air pump can be started during machining to suck dust, so that the cleaning property and safety are improved.
