2) wear-resisting fluted disc (18) is under the drive of high-speed electric expreess locomotive (20), waste and old circuit board is carried out secondary grinding pulverizing, water is injected to the inside of feeding cylinder (15) by loading hopper (16), water arrives between wear-resisting fluted disc (18) and slow cutting dish (17) under the promotion of binder helical structure (14), carries out depositing dust process;
3) when needing the abrasive material thickness regulating waste and old circuit board, by rotating hexagonal headpin (29) and then driving drive screw (30) to rotate, drive screw (30) constitutes screw-driven with right driver plate (32) and coordinates, and then drive that the outer case (25) that is attached thereto is overall fails to agree slip along slide rail (33), and then reduce the spacing between wear-resisting fluted disc (18) and slow cutting dish (17), and then abrasive material is made to attenuate;
4) in cutting process, waste and old circuit board abrasive material will be discharged along the discharging opening of seal closure (19), and then transport proceeds processing to next process.
