Nov 12, 2019 Because the jaw crusher is intermittent working, divided into work stroke and idling stroke, resulting in the motor load imbalance. In order to balance the load, the energy of the idle stroke is accumulated when the moving jaw leaves the fixed jaw, so that the energy can be fully released during the working stroke.
The no-load test run of the ball mill means idling without the installation of steel balls and ore materials. The idle time is generally not less than four hours, under normal circumstances it takes 8-16 hours to run. The longer the test run time, the better the running-in of the main bearing and gear tooth surface.
