Sorting and crushing system for comprehensive utilization of cement limestone

The sorting and crushing system comprises a base output assembly and a crushing mechanism, a vibrating mechanism assembled through bolts is arranged above one end of the base output assembly, and a screening suite assembled through bolts is arranged on the top side of the vibrating mechanism; a smashing mechanism assembled through bolts is arranged above the other end of the base output assembly. According to the device, after a first set of screen cloth, a coarse screen cloth, a second set of screen cloth and a fine screen cloth on a screening suite are vibrated through a vibration mechanism, materials are discharged out of the screening suite through a first discharging opening, a short discharging opening, a long discharging opening and an output nozzle; the materials are input into the crushing mechanism through vibration output of the long discharge port and the output nozzle, and after the materials are crushed, the similar materials can be input to the output belt through different output ports, so tha
