Planetary Ball Mills

planetary ball mill lab model

The planetary ball mill performs mixing by continually revolving the large plate and rotating the containers concurrently. Both the plate revolution (centrifugal) speed and container rotation (planetary) speed are independently adjustable. This unique mixing capability allows the operator to design precise solutions for mixing various systems. To further improve the mixing efficiency, grinding media can be added into the containers. Our machines are built in such a way that the strict weight balancing is not required. Our machines run very quietly with noise = 70 (dB). Ball Mill Jars and Balls are sold separately.
