## How to quickly solve jam problem in jaw crusher

1. In order to achieve a higher output, the user increases feeding capacity, which results in jaw crusher blockage. 2. Too much material in the lower chamber of the jaw crusher can't be discharged, so it resisters the moving plate and causes the motor to overload and stop. 3. The downstream equipment stops and the jaw crusher continues to break.

Analysis of ball and pulp flow in ball mills indicates that three factors may become critical with increasing mill diameters: ball size, fraction critical speed, and average pulp flow velocities. Ball diameters may need to be decreased and fraction critical speeds increased with ores which show decreased breakage rate coefficients above 1.2 mm (14 mesh). With 5.5-m (18-ft) and larger mills at ...
