Description

Technical Field

[0001] The utility model relates to the technical field of polysilicon, in particular to a novel silicon rod crushing production line. Background Art

[0002] See also Figure 1 Currently, polysilicon rods are transported by conveyor belts. After being manually knocked into small pieces by a hammer, they are crushed by a water-quenching crusher (with lower loss than ordinary crushers).

[0003] When operators use breaker hammers to hammer, the consumption is high and the efficiency is low. In addition, operators are prone to sweating during the hammering process, which can easily affect the quality of silicon materials and pose a risk of customer complaints.

[0004] In addition, after the silicon rods are manually knocked, the length of the small silicon materials obtained has large deviations (some are long and some are short), and the water quenching crusher requires the silicon rods to be longer. If the silicon rods are shorter, the water quenching crusher cannot be used and ordinary crushers must be used for crushing. In this way, ordinary crushers need to be kept on hand (such as using extrusion crushing), which increases the company's operating costs.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of implication that the information constitutes the prior art known to those skilled in the art.
