Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate production, in particular to a cooling device for calcium carbonate production. Background Art

[0002] Calcium carbonate is an inorganic compound, commonly known as: limestone, marble, stone powder, marble, etc. Its most common forms are calcite and aragonite, which are common minerals in the earth's crust. Calcium carbonate exists widely in nature, is the main component of many rocks, and is also the structural material of many organisms (such as shells, corals, and pearls). In the actual production and processing process, calcium carbonate often involves a calcination and drying process. After calcination and drying, the calcium carbonate powder has a high temperature due to its own heat. Therefore, before entering the next process, it is necessary to cool down the calcium carbonate powder.

[0003] At present, some calcium carbonate powders are cooled by natural ventilation, which has low efficiency. Some use a cold air blower to convey cold air to cool the calcium carbonate powder. However, the calcium carbonate powder is piled up or stacked, making it difficult to cool down quickly. There is still a large room for improvement in the cooling speed. Based on this, a cooling device for calcium carbonate production is proposed here. Summary of the Utility Model
