Complete Set of Vertical Lab Planetary Ball Mill


Please note:
For this ball mill, you require two or four grinding jars of your choice and the corresponding number of grinding balls. The grinding jar material must also be harder than the material to be ground. In normal cases, grinding jars and balls of the same material are used. To shorten the grinding time, larger or heavier grinding jars and grinding balls with a higher density can be used.
However, the standard packages of the mill don't include grinding jars or balls. They must be ordered as accessories.
Frequency Conversion Control System

Main Programs
Single direction without timing: samples need long or non-stop milling
Single direction with timing: samples need to be milled in one direction for a designated amount of time before automatic shutdown
Bi-direction with timing: i.e. samples need to run clockwise for 1.5 hours, then counter-clockwise for another 1.5 hours, and so on, for 15 total hours, before the machine shuts down itself

Single direction with paused interval and timing: i.e. samples need to run for 0.5 hours, then pause for 1 hour, then run for another 0.5 hours in the same direction and pause for another 1 hour, for 10 cycles before auto shutdown
Bi-direction with paused interval and timing: i.e. samples need to run clockwise for 0.8 hours, pause for 0.5 hours, then run counter-clockwise for 0.8 hours, for 20 cycles, before auto shutdown.
