Brief History of Laboratory Ball Mill
How the Planetary Ball Mill Was Developed:
Around 1960, German scientific and technical personnel developed high-energy grinding that achieved high-speed motion based on the motion rules of planets, breaking through the principles of traditional ball milling and improving grinding efficiency.
Epoch-making innovation: Centrifugal force + rotation superposition, energy density increased by 10 times, grinding efficiency and particle size have been greatly improved.
The development history of the PM series of planetary ball mills:
Around 1990, the PM 100 planetary ball mill was launched, becoming the world's first laboratory-grade planetary ball mill to achieve commercial operation.
Modernized iterative update: PM 200/400 series ball mills have achieved intelligent instrument control and multifunctionality.
Classification by grinding particle size
Particle size range Applicable models Typical applications
>100 μm PM 100 (conventional grinding) Coarse grinding of soil, ore, non-metal, metal
10–100 μm PM 200 Fine grinding of metal alloys, ceramic powders, pigments, coatings, etc.
<1 μm PM 400 (nanoscale) Micronization and nano-powdering of quantum dots, graphene, and pharmaceutical fine materials
Why Planetary Ball Mill?
The new motion principle makes grinding more refined: the tank rotates + the equipment revolves, and the grinding efficiency is at least 50% higher than that of traditional ball mills.
Controllable grinding particle size: The grinding particle size of the material can be accurately controlled by adjusting the speed of the equipment (100–650 RPM) and the grinding time.
Versatility of the new planetary ball mill: supports a variety of grinding modules: dry grinding, wet grinding, vacuum grinding, cryogenic grinding, etc. (optional modules are required).
Safety design: automatic shutdown for over-temperature protection, mechanical lock to prevent accidental opening of the cover, and external protective shell, etc.

FAQ (Frequently Asked Questions)
Q1: Can PM 100 be upgraded to the performance of PM 400?
→ *No, the hardware structure is different, but a nano tank can be added (limited to PM 200/400). *
Q2: How to prevent leakage during wet grinding?
→ Use silicone seal + PTFE tank, pressure self-locking design.
Q3: How to choose the material of the grinding ball?
→ It is recommended to be consistent with the tank material (such as zirconia tank with zirconia balls).
