Laboratory drum mill for large sample volumes
Efficiently process large volumes of diverse materials into precise particle sizes, ensuring consistent and reproducible results while integrating seamlessly into laboratory workflows.
Grinds and Homogenizes Large Sample Volumes
The Drum Mill TM 500 from Retsch is a laboratory ball mill that distinguishes itself by its capacity to handle large sample volumes up to 35 liters. Designed to pulverize, mix, and grind materials ranging from activated carbon to fine art paper, it operates on a principle of friction and impact within a rotating drum. The TM 500 excels in environments like research labs and production lines across industries such as pharmaceuticals, ceramics, and metallurgy, offering optimal integration with semi-automated laboratory setups. It supports a variable rotation speed from 10 to 50 rpm, allowing fine tuning of grinding processes for precise final particle sizes, down to 15 µm. Constructed from high-grade materials, including a 316L stainless steel option for food-grade applications, this mill ensures corrosive resistance and long-term reliability. Safety features like an emergency switch and an electronic tilt function enhance user operation. The TM 500’s programmability and optional sieving section streamline batch processing and ball/sample separation, facilitating seamless cleanup and maintenance.
