For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in,
These variations are it will be apparent that all are created using the utility model of the utility model design in the column of protection.
As shown in Figure 1, the pollution-free breaking polycrystalline silicon screening system, including jaw crusher and the vibration communicated therewith
Screening machine, wherein the model YC-1500 of screening machine is shaken in model PE600 × 900 of jaw crusher.
As depicted in figs. 1 and 2, which includes the crusher head connecting with motor of crusher 1, and broken electromechanics
Machine 1 is connect with control system 9, and preferably control system 9 is PLC control system；Wherein, crusher head includes the quiet jaw being mutually twisted
2 and dynamic jaw 3, and the dynamic jaw 3 is connect with motor of crusher 1, is moved under its drive.
It is mutually twisted as shown in Fig. 2, being respectively arranged on the occlusal surface of quiet jaw 2 and dynamic jaw 3, wavy groove, together
When, move jaw 3 with a thickness of between 20mm, with quiet jaw 2 with 22.3 ° of angle, and the material of quiet jaw 2 and dynamic jaw 3 all have it is not dirty
The performance of pSi powder is contaminated, preferably silicon nitride can be quickly and effectively by the angular compliance between quiet jaw 2 and dynamic jaw 3
Realize crushing to polysilicon, meanwhile, contact stain will not be generated with polysilicon, avoid in shattering process in pSi powder into
