Working Principle and Structure Features
The machine is mainly consisted by following parts:
1. Frame; 2. Fixed Jaw Plates; 3. Left and Right Guard Plates;
4. Movable Jaw Plates; 5. Movable Jaw; 6. Eccentric Shaft;
7. Toggle Plate; 8. Adjusting Base; 9. Adjusting Screw Stem;
10. Adjusting Wedge Block; 11. Fittings of Tension Spring
The eccentric shaft is driven by electric motor through V-belt and grooved pulley, and the movable jaw moves circularly, then the material in crushing cavity will be crushed.
The fixed jaw plates on front end of frame are fastened by right and left guard plates, while the movable jaw plate is fastened on movable jaw by lock block. If one end of the fixed jaw plate and movable...
