• Stable revolving speed of the gear transmission ensures the consistency and repeatability of the experiment
• Planetary movement principle is adopted in the machine, which has high speed, large energy, high efficiency, small Granularity
• Four powder samples from different sizes and different materials can be produced at one time
• The machine is controlled by frequency converter, you may choose ideal rotating speed according to expected experimental result.
• The converter is equipped with device of under voltage and over-current to protect the motor. 
• The planetary ball mill has functions of timing power off, self-timing forward and reversal rotating. You may choose freely any operation modes of one-way direction, alternation,
succession, time setting according to experimental needs, so as to improve efficiency of grinding
• Technical features of Korprotec Ball Mill: Low center of gravity, stable performance, compact structure, easy operation, reliable safety, lower noise, small loss.
• Safety switch is installed on the machine to prevent safety accident if the safety cover is opened while machine is running.
