BR40 is suitable for applications that require high fineness and can meet the technical requirements of colloid grinding. Its energy input even meets the requirements of mechanical alloy preparation. Inhigh-speedUnder the centrifugal force, the planetary ball mill generates crushing energy, which can grind the sample to the micrometer/nanometer level.

By high-speed grinding with a ball mill, ground samples are obtained and placed in a screening instrument for screening and grading to obtain samples with the specified fineness for testing.
