Semi Circular Arc Four Jars Planetary Ball Mill 0.75KW Planetary Ball Milling Machine for Ceramic Powder Milling

2L Semi Circular Arc Planetary Ball Mill with Four Jars — 0.75KW Grinder for Ceramic Powder Milling

Vertical planetary ball mills are essential equipment for high-tech material mixing, fine grinding, sample preparation, new product development, and small-batch production. Compact in size yet highly efficient and quiet in operation, they are an ideal choice for R&D institutions, universities, and enterprise laboratories seeking reliable sample results — with the ability to process four samples simultaneously in a single run. When paired with a vacuum ball mill tank, the machine can also produce powder samples under vacuum conditions.

The planetary ball milling machine is fitted with four ball grinding tanks mounted on a single turnplate. As the turnplate rotates, each tank axis performs planetary movement, causing the grinding balls inside to grind and mix samples at high speed. The unit can crush and blend a wide variety of materials of differing granularity using either dry or wet methods, achieving a minimum output granularity as fine as 0.1 micron (1.0×10^-4 mm).

It is widely used across geology, mining, metallurgy, electronics, construction materials, ceramics, chemical engineering, light industry, medicine, and environmental protection.

1. Particularly suitable for vertical stirring mills, horizontal roller ball mills, vibrating mills, and various high linear-speed pin-type sand mills.
2. Wet or dry ultrafine dispersion and grinding of pastes and powders without contamination.
3. Perfect grinding media with good flatness, smooth surface, bright finish, high density, and high strength.
4. Wear- and corrosion-resistant applications: coatings, textiles, pigments, and dyeing.
5. High-strength, high-tenacity products: magnetic materials, piezoelectric ceramics, and dielectric ceramics.
6. Pollution-prevention applications: medicine, food, and cosmetics.
7. Ceramics: electronic ceramics, refractory ceramics, and structural ceramics.

• Stable revolving speed via gear transmission ensures consistency and repeatability of experiments.
• Planetary movement principle delivers high speed, large energy, high efficiency, and small output granularity.
• Four powder samples of different sizes and materials can be produced in a single run.
• Frequency converter control allows selection of the ideal rotating speed for the expected experimental result; the converter includes under-voltage and over-current protection for the motor.
• Timing power-off and self-timing forward/reverse rotation functions; freely select one-way, alternating, or successive operation modes with time settings to improve grinding efficiency.
• Low center of gravity, stable performance, compact structure, easy operation, reliable safety, lower noise, and minimal loss.
• Safety switch prevents accidents if the safety cover is opened while the machine is running.
