Planetary ball mill for high throughput grinding
For precise material engineering, achieve efficient size reduction, homogenization, and nano-scale grinding with our advanced planetary ball mill, perfect for reducing high-density materials in research and development.
Grinds, Mixes, and Homogenizes Various Materials
The Planetary Ball Mill PM 400 from Retsch is a robust solution for precision grinding and mixing of small to large sample volumes. This floor model accommodates up to 8 samples simultaneously, ideal for research and development in industries such as materials science and pharmaceuticals. Its high-speed centrifugal mechanism efficiently reduces particles to achieve nanometer-scale fineness, crucial for applications like mechanical alloying and mechanosynthesis.
Equipped with four grinding stations, the PM 400 allows for batch-wise processing with digital controls that ensure reproducibility and safety. The integration of GrindControl offers precise temperature and pressure measurement within the jar, adapting to specific material requirements. Its adjustable speed ranges from 30 to 400 rpm, facilitating optimal particle size reduction while minimizing energy consumption.
Constructed with durability in mind, the mill comes with multiple material options for grinding tools, including stainless steel and tungsten carbide, suited for demanding environments. The Safety Slider feature prevents operation unless jars are securely clamped, ensuring both safety and ease of use. Maintenance is streamlined with easily interchangeable grinding jars and CIP compatibility, enhancing operational efficiency.
