Gravel crushing equipment for controlling granularity of concrete aggregate

The invention discloses gravel crushing equipment for concrete aggregate granularity control, and relates to the technical field of gravel crushing, the gravel crushing equipment comprises a feeding unit, a preliminary crushing assembly, a control assembly, a separation assembly, an output unit and a main machine box, the feeding unit is arranged at the top of the main machine box, and the main machine box is fixedly connected with the ground; the primary crushing assembly and the control assembly are arranged in the main machine box, the primary crushing assembly is arranged above the control assembly, the separation assembly is arranged on one side of the main machine box, and the output unit is connected with the separation assembly. The guide cone generates first-layer buffering on falling of gravel, the buffering plate generates second-layer buffering on falling of the gravel, impact potential energy is reduced, vibration generated by the guide cone causes the shifting piece to move up and down, the grav
