Calcination of calcium carbonate to produce quicklime is the traditional production process, with the development of science, the production of quicklime used mechanized, semi-mechanized shaft kiln and rotary kiln, fluidized bed furnace and other equipment. Calcination time is correspondingly reduced, lime rotary kiln production only need 2 to 4 hours. Compared with kiln production,it can improve production efficiency more than 5 times. In recent years, the use of Raymond mill for processing limestone improve the utilization value and scope of quicklime.

The use of limestone Raymond mill processing flow as follows: the raw limestone calcined by calcination equipment such as rotary kiln, the processed lime change into calcium oxide. Then the calcium into the mill’s host through the screw conveyor, under the joint action of the multilayer grinding rings and multiple rollers,it become fine limestone powder. Limestone powder are transported to storage silos under the action of wind, after removal equipment processing collected, lime will finish processing.
