[0002] Pyrophyllite is a kind of clay mineral, a layered hydrous aluminum silicate mineral with a crystal structure of 2:1, and its chemical formula is Al2[Si4O10](OH)2. Pyrophyllite has a fine texture and low hardness (1-2), and is suitable for making blanks (molds) for synthetic diamonds, ceramics, refractory materials, glass fibers, carving stones, etc. It can be widely used in ceramics, metallurgy, building materials, chemicals, light industry and other industrial sectors.

[0003] At present, most of the existing pyrophyllite is dried by hot air, electric heat and steam, etc., all of which use heat conduction, heat convection, heat radiation and other methods to first transfer heat to the surface of the heated object, and then gradually increase the center temperature through heat conduction. Therefore, these methods of drying pyrophyllite require a certain amount of heat conduction time, a long drying time and low efficiency.

[0004] To this end, in response to the above problems, we propose a pyrophyllite microwave drying device, which can dry the pyrophyllite material through microwave heating. It can directly act on the medium molecules (such as water molecules) to convert them into heat, and can penetrate the medium so that the inside and outside are heated at the same time without the need for heat conduction. Therefore, the overall temperature of the material can be increased in a short time, and the energy utilization rate is greatly improved, thereby achieving the purpose of pyrophyllite microwave drying.
