Planetary Ball Mills 101 Planetary ball mills share the same design as other basic ball mills – a grinding jar filled with media and rotated on its own axis But their unique design takes advantage of centrifugal force and the Coriolis effect to grind materials to a very fine or even micron size
Ball nosed cutters slow nose speed The biggest challenge with ball nosed end mills of various kinds is slow nose speed As you get closer to the tip the diameter on the ball gets smaller and smaller finally going to zero As a result the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut
Then the damage of ball mill scale board and grinding media will be less so will the energy consumption On the contrary if the grindability is high the damage and energy consumption of ball mill will be larger So the properties of raw material will directly affect the production rate and play most important role in the grinding process
