FRITSCH PULVERISETTE 14 Variable-Speed Rotor Mill

FRITSCH PULVERISETTE 14 rotor high-speed mill

The FRITSCH PULVERISETTE 14 rotor high-speed mill is an innovative laboratory mill for the precise grinding of soft to medium-hard materials and is particularly used in chemistry, pharmacy, food technology and materials science. It impresses with its flexibly adjustable grinding system, compact design and extraordinary versatility, which makes it the clear choice over many standard mills in the laboratory environment.

Precision grinding at the highest level

The rotor quick mill was developed to process a wide variety of materials quickly, reproducibly and with a high final fineness. At its heart is a powerful 1200-watt motor that allows a rotor speed of 6,000 to 20,000 rpm. This enables the rapid grinding of materials with a maximum feed size of 10 mm and a final fineness of d50 < 40 µm, depending on the selected sieve insert. The compact tabletop device (31 x 48 x 47 cm, weighing only 23 kg) fits flexibly into any laboratory.

The mill is suitable for both single batches and continuous operation and works according to the impact principle, which delivers particularly efficient grinding results. The grinding chamber design allows for easy cleaning and reduces cross-contamination, an important aspect when samples change frequently.

Technological highlights at a glance:

• Powerful 1200 W motor
• Rotor speed: 6,000 - 20,000 rpm, digitally adjustable
• Final fineness: d50 < 40 µm (depending on material)
• Maximum feed size: 10 mm
• Throughput: up to 5 l/h (depending on material and sieve)
• Versatile grinding tools: impact rotor, various sieve rings, pin insert, impact bar
• Grinding tools available in stainless steel, pure titanium and TiN-coated for optimum adaptation to the sample type

Other specific features include easy handling, individually programmable grinding parameters and particularly quiet operation. The intuitive user interface ensures precise adjustment of all process parameters.

Robust design and maximum safety

All essential safety-related components, such as automatic shutdown when opened and touch protection on rotating parts, guarantee reliable operation even in demanding continuous operation. The solid construction ensures durability and minimal maintenance requirements.

Energy efficiency and environmental aspects

The mill is not only powerful, but also extremely energy-efficient, thus contributing to cost and energy reduction in everyday laboratory work. Minimal losses due to optimised air flow and short grinding times protect the sample, the environment and the budget.

Certifications and standards for maximum safety

The rotor high-speed mill complies with all relevant CE directives and the relevant DIN standards for laboratory mills. It is equipped with state-of-the-art safety technology and is approved for use in academic, industrial and quality assurance laboratories.

Application examples from laboratory practice

The versatility of the rotor high-speed mill enables numerous areas of application, including:

• Pulverisation of inorganic and organic chemicals, e.g. salts, catalysts, polymers
• Comminution of pharmaceutical products such as tablets or granulates for quality assurance and active ingredient analysis
• Grinding and homogenisation of foodstuffs such as spices, cereals, sugar, rice, herbs and convenience products
• Comminution of samples for plastics, ceramics or metallogenic analyses in materials research (composites, powder alloys)
• Preparation of environmental samples, e.g. for heavy metal analysis in soils or sediments

FAQ - Interesting facts about the application

How is the desired final fineness achieved?

By selecting the appropriate sieve insert (0.08-6 mm) and precisely adjusting the rotor speed, the final fineness can be controlled with pinpoint accuracy - ensuring reproducible results.

What materials are available for the grinding tools?

Depending on the sample composition and cleaning requirements, grinding tools are available in stainless steel, pure titanium and TiN-coated.

Is it easy to convert to a different sample type?

Yes, the design allows for quick tool changes and easy cleaning. A tool change takes only a few minutes, so even sensitive samples can be processed.

What safety precautions protect the operator?

The mill has a sophisticated safety concept with automatic shutdown when opened, motor protection and overload protection, as well as comprehensive CE marking.

Conclusion

The FRITSCH rotor high-speed mill combines compact design, high energy efficiency and flexible application options. It is an ideal choice for laboratories that need a powerful, reliable and safe solution for grinding a wide variety of materials - from chemical substances and pharmaceutical products to foodstuffs and demanding research samples.
