Universal Cutting Mill PULVERISETTE 19. FRITSCH, Germany

תיאור

Unique grinding chamber geometry

Another advantage of FRITSCH Cutting Mills is their special grinding chamber geometry: Thanks to a progressively designed cutting geometry between the rotating cutting edges of the rotor and the fixed knives in the grinding chamber, the sample material is automatically transported away and thereby comminuted increasingly fine by shearing forces between the knives until the desired final fineness is achieved. In addition, the practical FRITSCH sieve cassette always automatically ensures the optimal distance to the rotor – and since there are practically no dead spaces, the sample material cannot come to a rest anywhere. At the same time, the special FRITSCH-airflow automatically transports the finished comminuted sample to the practical collecting drawer or a larger collecting vessel because of the strong air throughput. Your advantage: Faster work and more effective protection against clogging.

• Fast, reproducible comminution due to high cutting rotor rotational speed 2,800 rpm
• Max. feed size 70 x 80 mm
• Throughput of up to 60 l/h
• Defined final fineness due to interchangeable sieve inserts – 0.2 – 6 mm
• Collecting vessel 3 litres or 10 litres
• Easy, fast and thorough cleaning of the grinding chamber and of all cutting tools
• Standard funnel for long and bulk solids or protected funnel with sample pusher
• Variety of rotors available to adapt the cutting performance to suit the sample
• Stable running and low wear due to patented double cone bearing of the rotor
• Exceptionally long service life through use of replaceable rotor knives and fixed knives
• Cutting rotor and sieve cassette can be removed and replaced without tools
• Externally adjustable cutting gap
• Housing and closing lid can be lifted to open completely
• Smooth, easy-to-clean interior grinding chamber walls
• Optimal airflow for particularly fast size reduction and secure protection against clogging
• Sample exhauster with Cyclone separator
• For especially powerful and gentle comminution also with 300-360 rpm available
• 316 L-Version – available especially for the food and pharmaceutical industry
• Extensive accessories for simplifying your daily work

Unmatched simple cleaning!

While you are still tightening screws on other mills, your FRITSCH Cutting Mill is already clean. Because the entire grinding chamber can be opened easily in seconds and both the rotor and the sieve can be simply be removed with simple motions. The housing and closing lid can be lifted back completely, and the grinding chamber lid can be completely removed from its hinges.

The result: A completely open, empty grinding chamber with minimised dead space for simple quick cleaning and reliable protection against cross-contamination.

Opening up possibilities: the FRITSCH Cyclone separators

FRITSCH offers two models for your application needs: We offer a high performance Cyclone separator made of stainless steel 304 for sample exhaustion. Perfectly suitable for the analytical sector, food and pharmaceutical industry, as well as in combination with the corrosion-resistant stainless steel version of the Universal Cutting Mill.

In connection with the PULVERISETTE 19, the patented FRITSCH sample exhauster with the standard Cyclone separator ensures with its powerful vacuum function, based on negative pressure a simple feeding, fast throughput and good cooling, effectively prevents sample material from escaping during feeding and opens up new possibilities in the processing of heterogeneous mixture of materials, such as derived fuels in the cement industry.

NEW: powerful version for gentle comminution

Available immediately the PULVERISETTE 19 is also available with 300 – 360 rpm. This combination of low cutting speed and extreme cutting power offer an especially powerful comminution of hard, tough-elastic samples or small sample quantities – and is the ideal solution for all applications where for example thermal damages, the loss of volatile substances or the loss of a larger fine share is to be avoided. (Additional rotation speeds on request!)

NEW: Universal Cutting Mill PULVERISETTE 19 – especially for the food and pharmaceutical industry

The Universal Cutting Mill PULVERISETTE 19 is also available in a corrosion-resistant stainless steel version. It is FDA compliant and has an increased resistance to corrosive media such as alkalis and acids, but especially to chloride containing media.

Configure your Universal Cutting Mill PULVERISETTE 19 exactly to your specific application

Different funnels enable an optimal feeding of materials. Different rotors, for example with V-cutting edges, straight edges and disk milling cutter rotor with indexable inserts enable an optimal adaptation of the cutting performance to suit the sample. The patented FRITSCH sieve cassettes with trapezoidal and square perforations determine the final fineness of the sample, can be inserted quickly and easily and ensure automatically a constant distance between rotor and sample material. Your advantage: Always an optimal result. To accommodate the abrasion properties, cutting tools and sieve cassettes are available in different materials. A collecting vessel for 3 litres and for larger quantities, a collecting vessel for 10 litres may be utilized.

The PULVERISETTE 19 can be easily fixed to a table or the FRITSCH Universal support stand may be ordered.
