The design of glass lined mixing blades is scientific and reliable, with almost as many types as steel mixing blades, reflecting the exquisite and perfect production process. The safe and reliable freezing and disassembly method makes it possible to combine multiple types of mixing blades in a set of mixing system for glass lining, greatly facilitating the production process of materials with different properties in the same reaction tank. The process of disassembling and disassembling various types of mixing blades in the freezing technology is simple, and there is no need to remove the transmission device. It requires less time and can save expenses.
