Reclaimed rubber powder production device based on low-temperature crushing

The utility model discloses a reclaimed rubber powder production device based on low-temperature crushing, which comprises a rack, a crushing box and a grinding box are mounted on the rack, two crushing rollers are rotatably connected in the crushing box, crushing blades are mounted on the crushing rollers, cooling shells are mounted on two sides in the crushing box, the cooling shells are provided with inner cavities, and the inner cavities are communicated with the crushing box. A first communicating pipe is arranged on the smashing box, the input end of the first communicating pipe communicates with a refrigerant source, and the output end of the first communicating pipe communicates with an inner cavity of the cooling shell. Through cooperative arrangement of a cooling shell and a first communicating pipe, crushing blades on crushing rollers can be cooled through low-temperature gas in the cooling shell through self rotation in the process of cutting the waste tires, and therefore a large amount of heat g
