Description
Technical Field
The utility model relates to a grinding rotor of grinding equipment, in particular to a disc type rotor structure with a bar pin.
Background
Currently, in the lithium battery industry, a process route of lithium iron phosphate needs to pass through a coarse grinding section of a disc type sand mill and a fine grinding section of a rod pin type sand mill so as to achieve uniform slurry with required fineness and then sinter. Since the price of the lithium iron phosphate raw material is high, the smaller the fineness of the incoming material is, the higher the price is. Rough grinding and fine grinding processes are generally performed using a sand mill to obtain a smaller fineness. And in the rough grinding stage, a disc type sand mill is adopted for grinding under the working condition of ensuring that the material characteristics are not damaged and the grinding is mild. However, the ceramic disc rotor of the traditional disc sand mill has serious abrasion and is difficult to meet the productivity requirement under the condition of excessively coarse materials and matching large grinding media. Because the main shearing and grinding contact surface of the traditional disc type rotor is a cylindrical surface, the shearing area is small, and the rotating speed of the disc type sand mill is low, so that the impact force between the disc type sand mill and grinding beads and material particles is small, the grinding efficiency is difficult to achieve under the condition that the material characteristics are maintained by mild grinding, and the grinding period of batch materials is long. Meanwhile, most of disc type sand mills in the prior market are integrated disc type rotors, and for grinding slurry with higher hardness and larger particle size, the disc type rotors have long grinding time and serious rotor abrasion. And after the rotor is worn, only the disc type rotor can be integrally replaced, and the equipment maintenance cost is high.
