The excavator unloads the stones into the hopper, and the stone enters the vibrating feeder (model: 6013) from the lower part of the hopper.  The vibrating feeder feeds the limestone evenly to the jaw crusher(model:900*1200).  The material after being crushed by the jaw crusher is delivered to the first impact crusher(model: 1520). The crushed material from the first impact crusher comes into the second impact crusher(model: 1315) to crush. The output of the impact crushers will be sent to the first vibrating screen(2470-2), we can get 19-25mm and <19mm materials. Send the smaller than 19mm materials to the second vibrating screen. Then we can get the other three output products 0-6mm, 6-13mm, and 13-19mm. Each output will need one separate conveyor belt.
