Cutting mill for dry sample comminution
Achieve precise comminution of dry materials, from plastics to dried plants, with efficient high-speed cutting—ideal for rapid sample preparation and reproducible results in R&D and quality control settings.
Processes and Reduces Materials with Precision
The Cutting Mill PULVERISETTE 15 from FRITSCH is engineered to streamline sample preparation with precision in laboratories and industrial settings. It employs a high-speed rotor with double bearing support and adjustable cutting gaps for optimal material comminution. This results in rapid and reproducible size reduction of plastics, textiles, and agricultural materials to produce uniform granules or powders essential for quality control and analysis. Capable of processing up to 50 liters per hour with a maximum feed size of 70 x 70 mm, it integrates seamlessly into any processing line. The equipment is distinguished by its unique grinding chamber geometry that minimizes dead space and ensures blockage-free operations enhanced by an efficient airflow design. Tailored to meet diverse application needs, it offers a range of accessory options including various funnels, rotors, and sieve inserts. Its robust design and easy-cleaning features make it suitable for continuous and high-speed operations across industries such as chemistry, food processing, and environmental analysis, providing durable performance with extended rotor knife life.
