Impact Rotor for Fritsch Variable Speed Rotor Mill, 8-Rib

8-Rib Impact Rotor for Fritsch PULVERISETTE 14 Variable Speed Rotor Mill

The 8-Rib Impact Rotor is a fundamental component for the Fritsch PULVERISETTE 14 Variable Speed Rotor Mill, meticulously engineered for the high-speed, fine grinding of a wide array of materials. It is the ideal choice for processing medium-hard, soft, brittle, and fibrous substances. Its design is particularly effective for challenging materials such as straw, paper, plastics, and samples with high moisture content.

Crafted from high-quality, durable stainless steel, this rotor is built to last and can handle all standard grinding applications. The smooth, polished surface ensures minimal material adhesion, making it incredibly easy to clean and preventing cross-contamination between different samples—a crucial factor for maintaining sample purity. The rotor works by creating powerful impact and shearing forces as its eight ribs rotate at high speeds against a fixed sieve ring, enabling efficient size reduction and ensuring a rapid sample throughput.

It is important to note that the Variable Speed Rotor Mill requires both an Impact Rotor and a Sieve Ring to operate. The final particle size of the ground material is determined by the specific sieve ring selected.

Key Features & Specifications:

• Optimized for Diverse Materials: The 8-rib design is ideal for the rapid and effective fine grinding of fibrous samples, as well as medium-hard, soft, and brittle materials.
• Durable and Cleanable Construction: Made from smooth, low-wear stainless steel (AISI 316L) for robust performance, longevity, and simple, residue-free cleaning.
• High-Throughput Performance: The powerful impact forces generated by the rotor ensure efficient size reduction, leading to faster processing times.
• Essential System Component: Designed exclusively for use with the Fritsch PULVERISETTE 14 Variable Speed Rotor Mill.
• Customizable Grinding: Pair with different sieve rings to achieve your desired final particle fineness, from coarse pre-crushing to fine grinding.
• Variety of Options: In addition to the 8-rib rotor, other types are available, including 12-rib and 24-rib rotors, to precisely match different material properties and grinding requirements. A cast iron version is also available for specific applications.
