AM420 Planetary Ball Mill
The Ants Scientific AM420 Planetary Ball Mill is a high-energy laboratory grinding system designed for fine grinding and homogenization of a broad range of materials, from soft and medium-hard samples to hard, brittle, fibrous and tough materials.
Its planetary grinding mechanism combines the rotation of the grinding jars around their own axes with their orbital movement around the sun wheel. This creates high-energy impact and friction inside the grinding jars, enabling efficient pulverization and fine grinding.
The AM420 provides two grinding stations, giving laboratories greater sample throughput than the single-station AM410 while retaining the high-energy planetary grinding principle.
It is suitable for general fine grinding as well as more demanding research applications such as colloidal grinding, nanomaterial preparation and mechanical alloying.

Key Advantages
- Two grinding stations
Process two grinding jars simultaneously, increasing productivity for routine research and sample preparation. - High-energy planetary mechanism
High centrifugal forces and combined impact/friction effects provide efficient grinding of difficult samples. - Fine grinding down to submicron levels
The planetary ball mill series is designed for very fine grinding, with the manufacturer specifying approximately <1 µm for general grinding and <0.1 µm for colloidal grinding, depending on sample and conditions. - Flexible grinding programs
Forward/reverse rotation, intervals, pauses and two-stage grinding sequences can be programmed to optimize grinding and heat dissipation. - Multiple grinding jar materials
Available jar materials allow users to match the grinding system to the sample and contamination-control requirements. - Research-ready configuration
The AM420 is suitable for nanomaterial development, materials science and mechanical alloying as well as conventional sample preparation.
Applications
The AM420 Planetary Ball Mill is suitable for fine grinding, mixing and homogenization of a wide range of materials. With dry and wet grinding capability, it is well suited for both routine laboratory sample preparation and advanced research.
