Once they overheat and stop working, they won't work again. Use short 5-10 second pulses, shake the mill while you grind, and let the mill cool down before milling any more. WARNING: Do not confuse a blade-type coffee mill with a ball mill. The two types of mills work very differently. NEVER mill mixed chemicals together in a blade mill.

A typical end mill may be referred to as an "Upcut Spiral" by the CNC Router world. Other than small geometry changes to optimize for wood, end mills and upcut spirals are interchangeable. The more common spelling is "end mill", but I often use "endmill" as well. The two are pretty interchangeable. Carbide vs HSS End Mills

The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill ...
