In order to achieve the above object, the utility model adopts the following technical scheme:
a secondary crushing roller device for a crusher comprises a primary crushing roller consisting of a high-speed crushing roller, a low-speed crushing roller, a high-power driving motor, a low-power driving motor, a speed reducer I and a speed reducer II; the high-power driving motor and the low-power driving motor are assembled with the speed reducer I and the speed reducer II into a whole in a key connection mode, the high-speed crushing roller and the low-speed crushing roller are respectively installed on the base through a bearing seat, and the speed reducer II is connected with the low-speed crushing roller through a coupler; one end of the high-speed crushing roller is connected with the speed reducer I through a coupler; wherein: the string tooth crushing roller is characterized by further comprising a string tooth crushing roller, one end of the string tooth crushing roller is fixed on the base through a bearing seat, and a rotating shaft at the other end of the string tooth crushing roller is connected with the other end of the high-speed crushing roller through a chain wheel and a chain.
Furthermore, the string tooth crushing roller consists of a star wheel type striking tooth sheet, at least two string-shaped rods and a rotating shaft; the string-shaped rod is symmetrically and fixedly arranged on the star wheel type striking tooth sheets through mounting holes formed in the star wheel type striking tooth sheets, the star wheel type striking tooth sheets are fixedly arranged on the rotating shaft, and the distances between the star wheel type striking tooth sheets and the star wheel type striking tooth sheets are equal.
Furthermore, a chain wheel cover is arranged on the chain wheel chain.
Further, the space between the star wheel type striking tooth sheets is determined according to the requirement of crushing granularity.
Compared with the prior art, the utility model has the advantages of it is following:
firstly, the tailing powder can be better scattered, the expected granularity can be obtained by adjusting the rotating speed of the second-stage crushing roller, the arrangement of the chord-shaped rods and the tooth form and the tooth space of the star wheel type striking tooth, and different requirements of downstream users are met.
The second-stage crushing roller and the second-stage crushing roller adopt a string-tooth combined structure, and the star wheel type striking tooth sheet and the string-shaped rod are combined into a whole. When the string teeth are combined with the crushing roller to rotate, the mineral powder can be ensured to be simultaneously beaten and crushed in the horizontal and vertical directions.
Third, because the utility model discloses used the broken innovative design of second grade for the interval that the one-level crushing roller struck the tine can increase, has both guaranteed the unobstructed emission of material, can break up wet powdered ore that glues well again, has improved piling up and the excessive of material simultaneously effectively.
