Food samples - perfect homogenization with the knife mill GRINDOMIX GM 200
The diversity of foodstuffs with their often very different properties represents a challenge for food testing laboratories. Before the actual analysis, the sample materials need to be homogenized and reduced to a sufficiently small particle size. The Knife Mill GRINDOMIX GM 200 sets standards in food sample preparation: The cutting effect produced by the steel blades results in the perfect homogenization of samples with high water, oil, sugar or fat content.
From Graphite Powder to Graphite Power
Graphite plays a vital role as an electrode material in batteries, fuel cells, capacitors, and numerous industrial applications such as lubricants, conductive coatings, and composites. In battery technology, graphite particle size is a key determinant of battery capacity, cycle life, rate capability, and overall performance. Optimizing particle size and distribution is therefore critical for battery design and manufacturing. This joint report combines the expertise of Retsch, Microtrac, and Sugino to provide a comprehensive overview of graphite grinding, dispersion, and particle size analysis - supporting a deeper understanding of the entire process chain from milling and dispersion to analytical evaluation.
Green Cement - How Ball Milling Activates Clay for A Sustainable Future
The construction industry is rapidly evolving to meet the demands of sustainability, and green cement is at the forefront of this transformation. Traditional cement production is one of the largest sources of CO₂ emissions, mainly due to the energyintensive process of heating limestone and burning fossil fuels. Green cement tackles this issue by incorporating Supplementary Cementitious Materials (SCMs), such as activated clays, fly ash, and slag, which replace part of the conventional clinker - the primary source of emissions in cement. Activated clays are especially promising: they are abundant, locally available, and, when properly processed, can significantly reduce the carbon footprint of cement production.
How Cyclone Separators Redefine Efficiency and Cleanliness in the Lab
Cyclone separators deliver substantial benefits when used with mills in laboratory settings. While cutting mills or rotor mills are already frequently operated with a cyclone, also jaw crushers and disc mills benefit greatly from this setup. By using a cyclone, it is even possible to combine two mills directly: for example, a two-stage grinding process with a jaw crusher and a disc mill can be completed in a single step.
Innovative designs from recycled food waste
Food waste is a significant global issue that impacts the environment, economy, and society. Every year, millions of tons of food are wasted, contributing to greenhouse gas emissions, resource depletion, and economic losses. Food waste occurs at various stages of the supply chain, including production, processing, distribution, and consumption. The environmental impact of food waste is substantial, as it leads to the unnecessary use of water, energy, and land resources, while also generating methane emissions from decomposing organic matter in landfills.

Mechanochemistry: Working Toward a Sustainable Future
In the light of sustainability and Green Chemistry, mechanochemistry offers fast reactions in a solvent-free environment. Mass productivities often exceed the solvent-based reaction equivalents, and the work-up procedures are generally easier. Beside thermal, electrochemical and photochemical energy supply, a less known form of mechanochemistry is based on energy input by impact and shearing forces; typically ball mills are used to conduct those reactions. This article gives examples how mixer mills and planetary ball mills are successfully used to conduct mechanochemical processes.

Cyclone sets are the ideal solution for clean, efficient, and material-friendly sample dis-charge in modern sample preparation processes. They ensure highly efficient separa-tion of sample material from the airflow, reliably replacing conventional gravity dis-charge outlets.
New Solutions for Cement and Concrete
The cement and concrete industry is one of the key pillars of the global construction sector. Without cement, there would be no stable buildings, roads, or bridges: it is the binding agent of modern infrastructure. Every year, billions of tons of cement are produced worldwide to meet the growing demand for housing, transportation networks, and industrial facilities. The industry is characterized by stringent quality requirements, complex chemical processes, and continuous development toward more sustainable and energy‑efficient material technologies.

To ensure the highest level of functionality and aesthetics in dental care, modern dental laboratories combine craftsmanship with state-of-the-art technology.
Recycling hazardous waste from mines
Mine wastes, commonly referred to as tailings, is the byproduct generated during the extraction and processing of various kinds of ores. This waste material primarily consists of finely ground rock particles, water, and residual chemicals used in the extraction process. The management and disposal of mine wastes are crucial due to its potential environmental impacts, which include soil and water contamination. If not properly managed, these tailings can lead to significant ecological damage, affecting both terrestrial and aquatic ecosystems.
Reproducibility of Mechanochemical Reactions in the Mixer Mill MM 400
Reliable results can only be obtained with reliable instruments. The Mixer Mill MM 400 is known for its ease of use and fast grinding in terms of sample preparation prior to quality analysis. Conducting various mechanochemical reactions we have proven that the MM 400 provides reproducible results for both grinding stations with minimal standard deviations between different processes. This is due to the consistent frequency which is stable and reproducible in processes over time. It could also be demonstrated that results obtained with different MM 400 devices are also reproducible.
Reproducible and convenient sample preparation for reliable food analysis
Reliable analytical results can only be guaranteed if the entire sample preparation process is reproducible. A well-known standard in sample preparation of foodstuffs are ultra-centrifugal mills, which are used for rapid pulverization of soft, medium-hard, brittle and fibrous food. Retsch’s latest model, the ZM 300, offers decisive advantages for food analysis such as temperature monitoring for temperature-sensitive materials, improved sample throughput and well-thought-out handling for particularly ergonomic working.
Sample Preparation of Cannabis
Grinding up to 32 g cannabis flower buds with minimum sample loss in 2 min: The Mixer Mill MM 400 can be used for a very quick homogenization method for Cannabis samples in disposable tubes. Up to eight samples can be processed at the same time. The sample loss is minimized, and the extraction results show less standard deviation than those of manually ground samples in a classic grinder.
SM 50 innovations for food analysis
Today, the authentication of food is one of the central tasks of modern quality control and food safety. Increasingly complex supply chains and rising demands for product safety and traceability require analytical methods that deliver reliable, reproducible and verifiable results. The basis for this is precise sample preparation, as even minimal contamination or loss of certain sample fractions can diminish the significance of the analysis results from mass spectrometry, chromatography or molecular biological analyses.
