1. Standard method: The complete amount of material to be sieved is placed on the sieve with the finest mesh size. After sieving and weighing the fraction, the oversize is placed on the next larger sieve and sieved again. This procedure is continued until the complete sample is separated into fractions.
   
   
2. “Swiss Method”: The sample is first divided into the number of size classes to be determined and then each part is sieved individually with the corresponding sieve. This method can only provide reliable results if the sample division was carried out representatively to keep the particle size distribution in all part samples identical. The best results are obtained by rotary sample dividers, such as RETSCH’s PT100, which divide the initial material into 6, 8 or 10 identical partsamples.

1. The jet of air causes a continuous new orientation of the particles onthe sieve surface. Particles with sizes smaller than the sieve aperturesare sucked in by the vacuum cleaner.
   
   
2. When using sieves of 25 mm height, the inflowing air causes theparticles to impact on the lid which helps to destroy agglomerates.

The easy handling of grinding jars with a push-fit lid allows for a high sample throughput.

Always select a grinding jar size suitable for the sample volume (approx. 30% of the jar is filled with sample material). Grinding jars are provided in sizes ranging from 1,5 ml to 25 ml (not all sizes available in all materials).

The document “Grinding Jar Ball Charge” in the Downloads section provides details about usable volumes, maximum feed sizes and correct filling of the jars with grinding balls for dry and wet milling as well as cell disruption.

For efficient and contamination-free grinding processes the grinding jars are available in 6 different materials (no undesired abrasion).

The energy input increases with the density of a material. For pulverizing soft samples, materials with a low to medium density should be used, whereas for hard samples it is better to use high-density materials.

  typically used for pulverizing medium-hard to hard and brittle samples
  
  
• Stainless steel (density 7.7 g/cm³; hardness ≤ 245 HB, medium abrasion resistance):
  typically used for pulverizing medium-hard to hard and brittle samples
  
  
• Tungsten carbide (density 14.8 g/cm³; hardness 93.6 HRA; high abrasion resistance):
  used for grinding very hard, brittle sample materials
  
  
• Agate (density 2.65 g/cm³; hardness 6.5 – 7 Mohs, low abrasion resistance)
  a highly pure natural material suitable for pulverizing soft to medium-hard or fibrous samples. Due to its low-density agate is suitable for gentle grinding processes with low energy input.

저온 분쇄 (냉동 분쇄)의 경우 두 개의 운반 보조 도구, 절연 용기 (6 리터) 1 개, 안전 고글 한쌍으로 구성된 Cryo 키트의 사용을 권장드립니다.

냉동 분쇄의 경우 경화 강 또는 스테인레스 강을 사용하여 주시기 바랍니다. 다른 물질의 용기를 사용할 경우 내부 장력이 발생되어 극한의 온도 변화로 인해 파손이 발생될 수 있습니다.

주의:

우선적으로 용기에 시료와 볼을 투입 후 덮개를 잠군뒤 용기를 액체 질소로 채워진 용기에 운반 보조 도구를 사용하여 담궈줍니다. 일정 시간이 지난 뒤 (액체 질소가 더이상 끓어오르지 않을 때) 시료는 용기 내부에서 간접적으로 취화되고 이제 운반 보조 도구를 사용하여 분쇄기에 고정됩니다 (고정 뒤 운반 보조 도구를 제거합니다). 액체 질소는 절대로 내부에 유입되어서는 않되며 유입 시 용기 내에서 증발하여 내부에 상당한 과압을 유발하기 때문입니다.

분쇄용 볼과 분쇄 용기는 항상 같은 재질이 선택되어야 합니다.

분쇄용 볼은 다양한 직경으로 사용이 가능합니다. 가장 중요한 것은 효율 적인 분쇄를 위해 볼은 시료의 가장 큰 입자보다 약 3 배 이상이 되어야 합니다. 마모를 방지하기 위해 항상 동일한 직경의 볼을 사용해야합니다.

분쇄용 볼의 갯수는 분쇄 용기에 따라 달라집니다. 다운로드의 "Grinding Jar Ball Charge (분쇄용 볼의 투입)" 문서를 통해 건습식 분쇄 및 세포 파괴와 관련된 분쇄용 볼의 사용 가능 양, 최대 투입 크기 및 올바른 투입에 대한 자세한 정보를 확인하시기 바랍니다. 추가 정보는 다운로드 내 “Material Analyses of Equipment & Accessories (장치 및 액세서리의 물질 분석)“에서 확인하실 수 있습니다.

Bead beating is a technique used to lyse or disrupt cells and tissues to extract intracellular contents, including nucleic acids (DNA, RNA), proteins, and other cellular components. This method involves the vigorous agitation of a sample mixed with small, often spherical, beads in a closed container. The beads are made from various materials such as glass, ceramic, steel, or zirconium, depending on the type of sample and the desired outcome.

The process works by physically shearing the cells apart as they collide with the beads and each other due to the high-speed shaking or vortexing of the sample. The effectiveness of bead beating is influenced by several factors, including the size and material of the beads, the speed and duration of agitation, the type and strength of the cell walls or membranes being disrupted, and the volume and consistency of the sample.

Bead beating is a versatile technique used across a range of applications, from molecular biology and biochemistry to environmental science and food testing. It is particularly useful for processing difficult-to-lyse samples, such as yeast, fungi, algae, and tissues from plants and animals, as well as for homogenizing samples with mixed cell types. The method offers several advantages, including the ability to process multiple samples simultaneously, the potential for high-throughput automation, and compatibility with a wide variety of sample types.

Another RETSCH ball mill, the Mixer Mill MM 400, is well known for a process called bead beating, and thus also is a bead mill.

The MM 400 processes up to 20 samples in 1.5 or 2 ml Eppendorf tubes without cross contamination which saves time for the operator. Additionally, an adapter is available to accommodate up to eight 50 ml Falcon tubes. The optimal bead size for cell disruption varies based on the cell type; for bacteria and yeast, glass beads ranging from 0.75 to 1.5 mm are recommended, while smaller beads within the range of 0.1 to 0.5 mm are more suitable for fungi and microalgae.

For DNA or RNA extraction, smaller single-use tubes up to 2 ml are ideal, whereas larger vials like the 50 ml Falcon tubes are well-suited for processing cell suspensions up to 240 ml in total for proteins or metabolites. The optimum bead beating parameters vary according to cell type. It may take some experimenting to find the best results. Usually, 30 s (most microalgae) to 7 min (yeasts in general) of bead beating are required to fully disrupt the cells.

• Bead mills are primarily used for ultrafine grinding and the dispersion of particles to nano and sub-micron levels. They excel in processing liquid or paste-like materials. Planetary ball mills are used for mixing, homogenizing, and grinding across a broad range of applications, from soft to extremely hard materials. They are well-suited for achieving particle sizes ranging from a few micrometers down to the nano range.
• Bead mills are especially effective for materials that are difficult to grind, including pigments, nanoparticles, and pharmaceutical compounds. Planetary Ball Mills are versatile, allowing for dry, wet, and even cryogenic grinding. They are used in fields such as material science, metallurgy, pharmaceuticals, and chemistry for sample preparation and research.
• Material State: Bead mills are more suitable for liquid or semi-liquid materials, which makes them ideal for wet grinding applications. Planetary ball mills, on the other hand, are versatile, handling dry, wet, or even cryogenic materials.

Simultaneous processing of several small samples is possible with the multi-cavity jars and an adapter for reaction vials. This is a typical requirement, for example, for pharmaceutical, chemical and biochemical applications. The small cavity jars provide new opportunities for mechanochemical research activities involving small amounts of chemicals.

The cavities in the jars have an oval shape which ensures effective mixing. The pouring aids allow for safe sample handling. The multi-cavity jars are made of stainless steel, thus providing effective heat transfer to or from the sample.

The adapter accommodates up to 18 disposable reaction vials of 1.5 or 2.0 ml (e.g. Eppendorf vials) or nine 2.0 ml steel tubes. With its two grinding stations, the MM 500 control mixer mill can process up to 36 samples in one working run. Thus, the MM 500 control is the ideal bead mill for cooled cell disruption and high sample throughput. 2.0 ml steel tubes should be used if samples need to be frozen or heated, as polymeric reaction vessels cannot withstand mechanical load at extreme temperatures. The adapter is made of aluminium so that heat is efficiently transferred to and from the reaction tubes.

Controlling the temperature can be crucial in wet grinding processes or bead beating processes as many materials processed in bead mills are temperature-sensitive. Excessive heat can cause undesirable chemical reactions or physical changes, such as polymer degradation, color changes in pigments, or changes in the crystalline structure of materials. For cell disruption, proteins are very temperature-sensitive and degrade quickly. Maintaining an optimal temperature ensures the integrity of the material\'s properties. Another aspect is the viscosity: Temperature fluctuations can affect the viscosity of the slurry being processed, which in turn influences the grinding efficiency and the quality of dispersion. A stable temperature ensures consistent viscosity, which is critical for achieving uniform particle sizes and a stable dispersion.

To manage these issues, bead mills often incorporate temperature control mechanisms, such as cooling jackets or external chillers, which circulate a cooling fluid around the grinding chamber to dissipate excess heat. Some mills also feature temperature monitoring systems to enable precise control over the process conditions.

RETSCH offers two bead mills where the temperature can be controlled easily during wet grinding or bead beating: The High Energy Ball Mill Emax and the Mixer Mill MM 500 control.

Homogenization is a pivotal process in sample preparation, ensuring that the sample is uniformly mixed to achieve a consistent composition throughout. This uniformity is essential for accurate and reliable analytical results, as it eliminates the variability that could arise from analyzing different parts of a non-homogeneous sample. Homogenization is particularly crucial when the sample is heterogeneous or has multiple components, as it allows for a representative analysis of the entire sample.

Homogeneity is a critical premise for reliable sample analysis for several reasons:

In this crucial step of sample preparation Retsch can support with its Pellett Press PP40. The press compacts the powder to tablets with smooth surfaces, which are often required for XRF analyses. The accuracy of XRF analysis depends on the interaction of X-ray beams with the sample surface, and several factors related to the surface condition can impact the quality of the data obtained:

• A smooth surface ensures that the X-rays interact uniformly with the sample. Rough or irregular surfaces can cause scattering and absorption of X-rays in an uneven manner, leading to inaccurate or inconsistent results.
• Smooth surfaces help to achieve reproducible results across multiple measurements or samples. Variability in surface texture can introduce measurement inconsistencies, making it difficult to compare results.
• In bulk samples, a smooth and finely polished surface minimizes the effects of particle size variation. Larger particles on a rough surface might not be fully penetrated by the X-ray beam, leading to underrepresentation of their elemental composition in the analysis.
• For solid samples, good surface contact between the sample and the detector window is crucial. A smooth surface ensures closer contact, which is particularly important for light elements that have low-energy X-ray emissions, as these emissions are easily absorbed by air gaps or inconsistencies in surface contact.
• On a rough surface, elevated points can create shadow regions that are not adequately exposed to the X-ray beam, resulting in an incomplete analysis of the sample\'s elemental composition.

The chemical extraction of analytes from ground samples is a pivotal sample preparation step in analytical chemistry, environmental science, and biochemistry, aimed at isolating specific compounds for detailed analysis. This process is essential for monitoring environmental pollution e.g. with pesticides, assessing nutrient levels in soils, detecting hazardous substances, and conducting research in various scientific fields.

The choice of extraction solvent and technique is critical and is determined based on the nature of the analytes of interest and the matrix of the ground sample. Common techniques include solid-phase extraction (SPE), liquid-liquid extraction (LLE), solid-phase microextraction (SPME), and supercritical fluid extraction (SFE), among others.

The extraction process typically involves the solubilization of the target analytes into a suitable solvent, separating them from the solid matrix and other non-target components. Following extraction, the analytes may undergo further purification and concentration steps before analysis using techniques such as gas chromatography (GC), liquid chromatography (LC), or mass spectrometry (MS) to quantify and identify the compounds of interest.

The specific techniques and equipment used in sample preparation depend on the sample type (e.g., solid, liquid, gaseous), the matrix complexity, the analytes of interest, and the analysis technique (e.g., chromatography, spectroscopy, mass spectrometry). Proper sample preparation is critical for obtaining accurate, reliable, and reproducible analytical results. Retsch offers instruments for different steps of the sample preparation process:

Sampling and sample division, drying or embrittlement, clean-up and sieving, size reduction and homogenization, extraction as well as concentration and compaction. Each part of the sample preparation process is described in the following sections.

Some industry-specific standards provide guidelines and directions on the correct sampling process, for example DIN 51701-2:1985 in the coal industry. It contains, for example, the formula

G [kg] = 0.07 [kg/mm] x z [mm]

which indicates how much sample “G” must be extracted from a bulk sample with maximum particle size “z” to obtain a representative quantity. Taking a coal sample with a maximum particle size of 5 cm as an example, the following calculation applies:

G [kg] = 0.07 kg/mm x 50 mm
G = 3.5 kg

Consequently, the extracted sample amount for a sample with max. 50 mm particles should be at least 3.5 kg to make sure it is representative. For other materials than coal a different density should be taken into account.

Some industry-specific standards provide guidelines and directions on the correct sampling process, for example DIN 51701-2:1985 in the coal industry. It contains, for example, the formula

G [kg] = 0.07 [kg/mm] x z [mm]

G [kg] = 0.07 kg/mm x 50 mm
G = 3.5 kg

Consequently, the size reduction equipment chosen should be capable of taking 3.5 kg of the sample (and the initial feed size).

The materials used for RETSCH grinding tools can be grouped as follows:

• Metal (steel, cast iron, titanium)
• Ceramics (tungsten carbide, zirconium oxide, sintered aluminium oxide, hard porcelain)
• Natural stone (agate)
• Plastics (PTFE, PP, PC)

Important considerations when choosing the optimized size reduction equipment for special tasks include:

• Properties of the material (like breaking behavior)
• Sample feed size
• Required final fineness
• Feed quantity
• Material of the grinding tools

The Ball Mill Work Index (BWI) is used for the range from 2.1 mm down to 100 µm. The sample needs to be pre-crushed to particle sizes as defined below.

• Minerals: < 3.35 mm and sieved
• Drillcore: < 3.35 mm and sieved
• Half Drillcore: < 3.35 mm and sieved

The optimum number of grinding balls is 285. With the ball diameters varying due to wear, the overall number should be adjusted from time to time to ensure a total mass of 20.125 grams.

The grinding jar of the Bond Index Ball Mill measures 12\'\' x 12\'\' and has well-rounded corners.

The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm. The sample needs to be pre-crushed to particle sizes as defined below.

• Minerals: < 12.50 mm and sieved
• Drillcore: < 12.50 mm and sieved
• Half a drillcore: < 12.50 mm and sieved

The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design.

Another application area of the TM 300 is Bond Index Testing. The Bond Work Index is used to assess the grinding efficiency and to calculate the necessary grinding power when choosing size reduction equipment in the design phase of, for example, a mining plant. Precise determination of BWI is crucial for the accurate design and estimation of costs linked to the comminution process in industries like cement, mining or steel.

Both the Ball Mill and the Rod Mill module can be used for the process. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit.

• Wood chips: Efficient size reduction of larger sample volumes
• PC boards: Pulverising solid PCBs with the 6-disc rotor for precious metal analysis
• Leather and table tennis balls: Comminution of textiles and rubber using the cyclone for rapid sample discharge from the grinding chamber
• Secondary fuels: Efficient comminution of highly heterogeneous materials for rapid calorific analysis
• Hay: Reproducible size reduction of fibrous, light and voluminous materials
• Injection moulding sprues: Grinding at low speeds to minimise fines (dust) content
• Toys: crushing of tough plastics by embrittling samples with liquid nitrogen

• Up to 100% sample recovery
• Grinding of small sample quantities without contamination
• On average 30% less cleaning time

• Minerals: < 3.35 mm and sieved
• Drillcore: < 3.35 mm and sieved
• Half Drillcore: < 3.35 mm and sieved

• Variable speed from 1 to 80 rpm
• Grinding time of up to 99:59:59 h:min:s
• Rotation direction, e. g. to reduce caking effects
• Programmable interval & break options for temperature-sensitive samples
• Delayed start function

• Minerals: < 12.50 mm and sieved
• Drillcore: < 12.50 mm and sieved
• Half a drillcore: < 12.50 mm and sieved
