Feb 16, 2018 Homemade Double-Barrel Ball Mill Ball milling replaces potentially unsafe hand grinding of chemicals and compositions. The crushing of the material is accomplished by the repeated falling of heavy balls onto it, over and over, inside the mill jar. So, it sounds like I need a ball mill.
mill drive obtained during various working shifts. The research shows that during the continuous operation of the mill the temperature of the motor in the bearing area increases for the first 3.5 h in an asymptotic manner in the range from about 45 C to 90 C. In the second stage, the bearing temperature oscillates between 90 C and 97 C.
