Its chemical formula shows that lithium manganese oxide is composed of three elements: lithium, manganese and oxygen, with the ratio of manganese to oxygen being 2:4. Lithium manganese oxide drying is the process of heat-treating lithium manganese oxide crystals or solutions containing water to make them lose water.

[0003] The existing drying process for lithium manganese oxide production is to spread the lithium manganese oxide flat on a baking tray, a mesh belt or directly put it into a hot air circulation oven, and dry the lithium manganese oxide by circulating hot air in the drying oven. Since this method takes a long time to dry, it leads to a long preparation time for lithium manganese oxide, which affects the drying efficiency of lithium manganese oxide. In addition, it is easy to cause uneven drying. After drying, the lithium manganese oxide needs to be taken out of the oven manually, which is inconvenient.

[0004] Therefore, it is necessary to design a lithium manganese oxide production drying processing device that can quickly and evenly dry lithium manganese oxide, improve the drying efficiency of lithium manganese oxide, and can automatically unload lithium manganese oxide to improve the convenience of unloading.
