Introduction:
The VRBM1600 Variable Speed Ratio High-Energy Ball Mill is a planetary-type high-energy mill capable of reaching rotation speeds up to 1600 rpm. It is designed for grinding, mixing various powder materials, or performing mechanical alloying of metallic materials (compatible with 4×500ml milling jars).
The mill features independent control of both jar rotation (up to 1600 rpm) and planetary revolution (up to 400 rpm). This unique capability allows operators to freely adjust the revolution-to-rotation speed ratio according to different material requirements, enabling precise modulation of impact forces and shear forces during ball milling or mixing processes. Such flexibility ensures optimal processing results for various grinding and mixing applications.
The equipment is widely applicable for synthesizing novel nanocrystalline materials, functional materials, and composites through methods including:
• Mechanical alloying
• Mechanical compounding
• Mechanochemistry
Working principle:
The VRBM1600 Variable Speed Ratio Planetary High-Energy Ball Mill operates on the planetary motion principle. Grinding balls move at high speeds inside the milling jars, utilizing intense friction and impact forces to pulverize samples – capable of grinding materials down to below 1μm rapidly.
Its defining feature is the arbitrarily variable transmission ratio between jar revolution and rotation speeds. By adjusting this revolution-to-rotation ratio, users can freely modify grinding conditions without limitations. This flexibility allows the mill to simulate grinding processes of various conventional ball mills.
