[0024] The specific settings and effects of the embodiment are described below. The high-calcium limestone enters the inside of the dust closed bin 5 through the feeding pipe 51, and then falls into the inside of the crushing bin 2. Then the driving motor 4 drives the crushing roller 3 to rotate, and the crushing roller 3 drives a plurality of limestone crushing blades 31 to rotate. The limestone crushing blades 31 and the extrusion crushing blades 21 cooperate with each other to extrude and crush the high-calcium limestone. The dust generated by crushing falls to the bottom end of the crushing bin 2, and part of the dust floats on the inner wall of the dust closed bin 5. At the same time, the pump pumps water into the inside of the water inlet pipe 61, and then the water flows into the inside of the water guide pipe 62 through the water inlet pipe 61, and finally is sprayed out from one end of the water outlet nozzle 63. The dust floating on the inner wall of the dust closed bin 5 is subjected to dust removal operation, so as to avoid dust agglomeration and pollution of the working environment. At the same time, the protective screen 7 arranged between the crushing bin 2 and the dust falling assembly 6 can isolate the crushed stones generated during the crushing process in the inside of the crushing bin 2, and only allow the dust to pass through the protective screen 7 to enter the inside of the dust closed bin 5, so as to protect the dust falling assembly 6 and ensure the stability of the dust falling assembly 6 during working.
