Ball mill is typically used to grind and/or blend materials and it can be done wet or dry. It can be used to mix ceramic powders, disperse particles in solvents, homogenize ceramic slurries, etc. Ball mills operate by rotating plastic jars around a horizontal axis, partially filled with the material to be ground plus the grinding medium.

Powerful black powder can be made with mill runs of between 2 and 4 hours. Use long drop cords. Unplug the cords at the electrical source, not at the ball mill, when you want to stop the mill. Run your mill remotely, outdoors, at least 150 feet away from people and inhabited buildings.

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature.
