Impact Rotor for Fritsch Variable Speed Rotor Mill, 12-Rib

Fritsch Impact Rotor, 12-Rib for PULVERISETTE 14 Variable Speed Rotor Mill

The 12-Rib Impact Rotor is a core component for the Fritsch PULVERISETTE 14 Variable Speed Rotor Mill, engineered for the rapid, fine grinding of a diverse array of materials. It is particularly effective for processing medium-hard, soft, brittle, fibrous, and tough substances. This makes it an ideal choice for challenging samples such as straw, film, paper, plastics, and other materials with high cellulose content, as well as samples with high moisture.

Superior Grinding Performance The rotor operates by generating powerful impact and shearing forces. As the mill spins at high velocity, the 12 hardened steel ribs strike the material, forcefully throwing it against the fixed sieve ring. This intense, repeated action ensures extremely efficient particle size reduction and delivers a high throughput, making it suitable for both routine sample preparation and demanding research applications.

Construction and Durability Manufactured from high-quality, corrosion-resistant stainless steel, this rotor is built for longevity and consistent performance even under heavy use. Its robust design minimizes wear and tear, ensuring a long service life. The smooth surfaces of the rotor are specifically designed for easy and thorough cleaning, which is crucial for preventing cross-contamination between different samples and maintaining the integrity of your results.

Operational Requirements For the complete operation of the PULVERISETTE 14 Variable Speed Rotor Mill, both an Impact Rotor and a compatible Sieve Ring are required. Sieve rings are available in various aperture sizes, allowing you to control the final particle size of your ground sample.

Key Features:

• Optimized for Fibrous Materials: The 12-rib configuration is expertly designed for the fast and effective fine grinding of fibrous, tough, and moist samples.
• Durable Stainless Steel Construction: Made from smooth, low-wear stainless steel (AISI 304) for reliable, long-term performance and simple cleaning.
• High-Throughput Grinding: The combination of powerful impact and shearing forces ensures rapid and efficient size reduction for a wide range of sample types.
• Versatile Application: Effectively grinds medium-hard, soft, brittle, tough, and fibrous materials, making it a flexible tool for any lab.
• Essential System Component: A necessary part for use with the Fritsch PULVERISETTE 14 Variable Speed Rotor Mill.
• Wide Range of Options: To accommodate different material properties and desired final fineness, other rotor types (such as 8-rib and 24-rib rotors) and various sieve ring sizes are also available.
