Hi Abbas. Thank you for your question.

In general, the normal running temperature of bearing box is around 40 degrees to 60 degrees, and the maximum temperature is 70 degrees. If the temperature is over 80 degrees, it is proved that there are some problems happen to the bearing box, and you need to stop to repair.

Next, when sand making machine runs over-load, the feeding size can’t be over the maximum required size.

Besides, when feeding materials to sand making machine, there is a nonequilibrium process lasting 30 seconds to 60 seconds, and you can’t stop feeding materials this time until the vibration weakens. When the size is a little big, there will be intermittent vibration lasting a few seconds. You needn't be nervous because it is normal.

Finally, you can check the current of sand making machine timely. If the current is too big and the motor is overloaded, you needn’t reduce feeding amount until current recovers.
