Fritsch Standard Universal Cutting Mill: Precision Size Reduction for Diverse Materials

The Fritsch Universal Cutting Mill PULVERISETTE 19 stands as a pinnacle of engineering for efficient and precise size reduction. Designed for versatility, this robust mill excels in processing soft to medium-hard and fibrous materials, making it indispensable across a multitude of industries. With a variable rotational speed ranging from 300 to 3,000 rpm, it offers unparalleled control for a wide array of applications, including plastics, textiles, agriculture, construction materials, food products, and even pharmaceuticals. Its sophisticated design permits the processing of larger starting materials and achieves higher throughput rates compared to many conventional mills.

How It Works: The Precision Cutting Principle

At the heart of the PULVERISETTE 19's efficiency is its unique cutting mechanism. Material is introduced into the grinding chamber, where it is subjected to the powerful interaction between a high-speed rotor and strategically positioned fixed knives. This action mimics the precision of a pair of scissors, cleanly cutting and reducing the sample. Continuous movement within the chamber ensures thorough processing, preventing material build-up. The comminuted sample remains in the chamber until it is fine enough to pass through the selected sieve insert, at which point it is collected in an integrated vessel. All operational controls, including power and rotational speed adjustments, are conveniently located on the instrument's front panel for ease of use.

Optimized for Standard Applications

This standard-sized mill is perfectly suited for a vast range of laboratory and industrial tasks. It accommodates a maximum feed size of 70 x 80mm and boasts an impressive maximum throughput of up to 60L/h, though actual performance may vary based on material characteristics, funnel type, and sieve size. Users can achieve final fineness levels ranging from 0.1 to 20mm, customizable through a selection of sieve inserts and rotor configurations. For applications demanding even greater capacity, Large Universal Cutting Mills are also available, offering increased maximum feed sizes and faster throughputs.

Essential Accessories for Tailored Performance

To ensure optimal performance and adaptability for every sample type, the Fritsch Universal Cutting Mill requires specific accessories, all available for separate purchase:

• Cutting Tool Sets: These consist of the rotor and fixed knives, crucial for the cutting action. Options include V-cutting edge, notched edge, or straight edge rotors, each designed for specific material properties and desired outcomes.
• Funnel: Various funnel types are available to facilitate smooth and efficient material feeding.
• Sieve Inserts: Available with trapezoidal or square perforations in a broad range of sizes (0.2–10mm), allowing precise control over the final particle size.
• Collection Vessel: Essential for cleanly gathering the processed material.

Diverse Applications

The PULVERISETTE 19 is an invaluable tool across numerous fields:

• Agriculture: Soil analysis, plant material preparation.
• Construction Materials: Sample preparation for quality control.
• Environmental Research: Waste analysis, plastic recycling studies.
• Food Industry: Spices, grains, dried fruits, quality control.
• Pharmaceuticals: Tablet grinding, herbal preparations.
• Plastics: Granulation of films, fibers, and hard plastics.
• Plants: Botanical studies, herbal remedies.
• Textiles: Fiber analysis, fabric shredding.
• Wood: Wood chips, sawdust for biomass research.
• Derived Fuel (RDF): Preparation of waste for energy production.

Key Features & Benefits

• Unmatched Cleanliness: The fully hinged grinding chamber and removable lid allow for complete access, ensuring fast, thorough, and residue-free cleaning between samples, preventing cross-contamination.
• Adaptable Rotors: A variety of rotor options are available, enabling precise adaptation of the mill to the specific characteristics of virtually any sample material.
• Enhanced Safety: An integrated safety circuit immediately halts the rotor's operation the moment the instrument is opened, ensuring operator protection during use and maintenance.
• Optimized Air Flow: A high-efficiency filter system ensures optimal airflow within the grinding chamber. This not only facilitates faster milling but also protects against sample overheating and material degradation.
• User-Friendly Interface: All control elements are intuitively placed on the front panel for easy operation.
