[0002] Heavy calcium carbonate, referred to as heavy calcium, is an important and widely used inorganic salt. Heavy calcium carbonate is made by grinding natural carbonate minerals such as marble and limestone. It is a white powder, odorless and tasteless. It is a commonly used powdered inorganic filler. Heavy calcium carbonate is a filling material and is widely used in many industries, such as artificial floor tiles, rubber, plastics, papermaking, coatings, toothpaste and other daily chemical industries. It is a green, environmentally friendly, energy-saving and emission-reducing material that meets the national requirements for non-metallic mineral materials.

[0003] At present, the existing drying devices have relatively simple structures and functions. Most of them can only dry the calcium carbonate poured into the device. A large amount of calcium carbonate is in the device, and some calcium carbonate piled deep at the bottom may not be effectively dried, resulting in uneven drying of the calcium carbonate, making some areas too dry and some areas still wet. Personnel are required to dry the calcium carbonate multiple times, which not only increases the production cost, but also greatly reduces the drying efficiency, thereby reducing the practicality of the device. Therefore, we propose a heavy calcium carbonate material drying device to solve the above problems. Utility Model Content
