Description

Technical Field

[0001] The utility model belongs to the technical field of lime production, and in particular relates to a special particle size limestone sorting device for lime production. Background Art

[0002] The original lime production process involved layering limestone and fuel (wood) and calcining them for a week. Modern production utilizes mechanized and semi-mechanized vertical kilns, rotary kilns, and fluidized bed furnaces. This shortens calcination time, with rotary kilns taking only 2 to 4 hours to produce lime, increasing production efficiency by more than five times compared to vertical kilns. In recent years, significant energy-saving processes and equipment have emerged, including cross-flow, double-slope, oil-fired circular vertical kilns, and short rotary kilns with preheaters. Fuels have also expanded to include coal, coke, heavy oil, and liquefied petroleum gas.

[0003] At present, the existing lime production special particle size limestone air separation equipment will generate a lot of dust in the process of air separation of particle size limestone, which will pollute the surrounding air environment and affect the normal function of the workers. Moreover, the dust will cause diseases after being inhaled into the human body, which is not conducive to the long-term work of the workers. For this reason, we propose a lime production special particle size limestone separation equipment. Utility Model Content
