Technical details and performance features

The planetary mill combines powerful technology with intuitive operation and precise controllability. Particularly noteworthy is its ability to process samples in the micro and sub-micrometre range reproducibly, as well as its safe operation under protective gas atmosphere - a decisive advantage for numerous chemical and sensitive material samples. The device is characterised by the following key technical features:

• Planetary mill with variable working principle (impact, friction)
• Grinding bowl volume: 80 / 250 / 500 ml; optimal sample sizes from 10 ml to 250 ml
• Various grinding tools and materials: agate, sintered corundum, silicon nitride, zirconium oxide, stainless steel, hardened steel, tungsten carbide
• Final fineness below 1 µm, typical grinding time to analytical fineness approx. 4 minutes
• Flexible speed control: 100 - 650 rpm (main disc)
• Centrifugal acceleration: up to 29 g; transmission ratio 1 : -1.82 (planetary disc to grinding beaker)
• Direct measurement of gas pressure and temperature possible
• Batch operation, dry and wet grinding, as well as operation under protective gas
• External controllability for integration into automated processes
• Compact as a tabletop device with dimensions of 37 x 53 x 50 cm, weight: 63 kg

The combination of a powerful motor (0.75 kW, 1100 W connected load), versatile sample intake and comprehensive process control enables consistent results even with demanding sample types such as metal powders, ceramic materials or biological tissue. The timer function supports reproducible processes, and the user-friendly display makes operation much easier than with other models.

Certifications and standards

Compliance with international standards guarantees reliable and safe use. The planetary mill complies with VDE 0530 and EN 60034, meaning that the motor and control system meet the highest requirements for electrical safety and quality. These certifications are particularly essential in industrial and research-based laboratory environments.

Practical applications

Its versatile functionality makes this device an all-rounder, especially when reproducible results and the safe processing of a wide variety of substances are required. Typical, practical applications include:

• Materials research: grinding of solid materials such as metals, ceramics, alloys, and synthetic and natural minerals.
• Chemistry laboratories: homogenisation and fine grinding of catalytically active substances, pigments, plastic compounds, and additives.
• Life sciences: Disintegration and pulverisation of plant tissue, cell material and biological samples for further processing, such as DNA/RNA extraction.
• Pharmaceutical industry: Fine grinding of active pharmaceutical ingredients (API), excipients and auxiliary substances for the development of new drug forms.

Special applications such as the processing of lithium-ion battery materials (e.g. lithium metal oxides), catalyst powders or industrial ceramics can also be carried out safely and efficiently with the PULVERISETTE 6 classic line.

FAQs

How is the speed controlled?

The speed can be precisely set from 100 to 650 rpm directly on the clear, digital control panel, allowing the grinding result to be optimally adapted to the respective sample material.

What sample quantities can be processed optimally?

The system is designed for flexible sample sizes from 10 to 250 ml, depending on the grinding beaker used. This efficiently covers both small analytical quantities and medium-sized laboratory batches.
