The staff can open the collection box 201 at any time to clean the inside of the collection box 201, so as to clean the dust, avoid pollution to the environment and adverse effects on the working environment, and improve the production environment of the lime production line. Then the staff begins to open the multiple sealing doors 113, and the crushed limestone inside the cylinder 101 begins to fall onto the conveyor belt 204. The staff starts the conveyor belt 204, and the conveyor belt 204 starts to move and moves the conveyor belt 20 The limestone powder on 4 is preheated by the preheater 205, and then falls vertically into the square box 206 through the conveyor belt 204. At this time, the limestone powder inside the square box 206 is conveyed by the auger conveying pipe 1 207, and is conveyed to the lime kiln 208. It is heated by the lime kiln 208. Under high temperature, the calcium carbonate in the limestone decomposes and releases carbon dioxide to produce quicklime. The calcined quicklime needs to be processed and extinguished. After the lime is extinguished, lime gypsum will be formed. The extinguished lime gypsum can be further refined and processed. When the lime gypsum is dried, it is conveyed to the fine grinder 211 through the auger conveying pipe 210. The fine grinder 211 is used to finely grind the lime gypsum to produce lime powder.
