    The CryoMill is tailored for cryogenic grinding. The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process. Thus the sample is embrittled and volatile components are preserved. The liquid nitrogen circulates through the system and is continually replenished from an Autofill system in the exact amount which is required to keep the temperature at -196 °C.
    Powerful impact ball milling results in a perfect grinding efficiency. The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility (cryogenic, wet and dry grinding at room temperature) makes the CryoMill the ideal grinder for quantities up to 20 ml.

    You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time.

    Application Examples

    Animal Feed, Bones, Chemical Products, Food, Hair, Oil Seeds, Paper, Plant Materials, Plastics…

    Product Advantages

    • Powerful cryogenic grinding by impact and friction, up to 30 Hz
    • 3 different grinding modes (cryogenic, dry or wet at ambient temperature)
    • Closed LN2-system (autofill) for enhanced safety, avoids any contact of the user with LN2
    • Screw-top grinding jars for convenient, leak-proof operation
    • Wide range of accessories including various LN2 feeding systems, jar and ball sizes, adapter racks, materials
    • Low LN2-consumption
    • Clearly structured user interface, memory for 9 SOPs
    • Programmable cooling and grinding cycles (10 s to 99 min)
    • Ceramic jar available

    Function Principle

    The grinding jar of the CryoMill performs radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jar and pulverize it.

    The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process.

    Thanks to its robust design, the Disc Mill DM 200 can be used under rough conditions in laboratories and pilot plants, as well as online for the quality control of raw materials. The powerful DM 200 requires only a few minutes to achieve the desired grind size.

    Application Examples

    Bauxit, Cement Clinker, Chalk, Chamotte, Coal, Concrete, Construction Waste, Coke, Dental Ceramics, Dried soil Samples, Drilling Cores, Electrotechnical Porcelain, Ferro Alloys, Glass…

    Product Advantages

    • Excellent crushing performance
    • Reproducible results due to accurate gap setting
    • Hinged grinding chamber for easy cleaning
    • Grinding discs with long working life
    • Wide range of materials for contamination free grinding
    • Connector for dust extraction
    • Can be operated together with Jaw Crusher BB 200

    Function Principle

    In the DM 200 the feed material enters the dust proof chamber from the filling hopper and is fed centrally between two vertical grinding discs. A moving grinding disc rotates against a fixed one and draws in the feed material. The necessary comminution effects are generated by pressure and frictional forces. The progressively arranged grinding disc meshing first subjects the sample to preliminary crushing; centrifugal force then moves it to the outer regions of the grinding discs where fine comminution takes place. The processed sample exits through the grinding gap and is collected in a receiver. The gap width between the grinding discs is continuously adjustable and can be adjusted during operation in the range between 0.1 and 5 mm; an additional observation window is provided for checking the gap setting.

  • The Emax is an entirely new type of ball mill for high energy milling. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time.

    Application Examples

    Alloys, Bones, Carbon Fibers, Catalysts, Cellulose, Cement Clinker, Ceramics, Chemical Products, Clay Minerals, Coal, Coke, Concrete, Fibers, Glass, Alloys, Cellulose…

    Product Advantages

    • Faster and finer grinding than any other ball mill
    • Speed of 2000 min-1 allow for ultra-fast pulverization of the sample
    • Water cooling permits continuous operation without cool down breaks
    • Temperature-controlled grinding
    • Narrow particle size distribution thanks to special jar design which improves mixing of the sample
    • Patented drive concept
    • Easy operation via touch screen, 10 SOPs storable
    • Operation with 2 grinding jars
    • Easy installation of grinding jars
    • Jars with integrated safety closure
    • Range of jar materials allow for contamination free grinding

    Function Principle

    The novel size reduction mechanism of the Emax unites the advantages of different mill types: high-frequency impact (mixer mill), intensive friction (vibratory disc mill) and controlled circular jar movements (planetary ball mill) allow for unrivaled grinding performance. This unique combination is generated by the oval shape and the movement of the grinding jars. The grinding jar supports are mounted on two discs respectively which turn in the same direction. As a result, the jars move on a circular course without changing their orientation.

    The interplay of jar geometry and movement causes strong friction between grinding balls, sample material and jar walls as well as a rapid acceleration which lets the balls impact with great force on the sample at the rounded ends of the jars. This significantly improves the mixing of the particles resulting in smaller grind sizes and a narrower particle size distribution than has been possible to achieve in ball mills so far.

    The French pressure cell press, or French press, is an apparatus used in  biological experimentation to disrupt the plasma membrane of cells by passing them through a narrow valve under high pressure.

    The French Press can also be used for disintegration of chloroplasts, homogenates of animal tissue, and other biological particles. It is capable of disrupting cell walls while leaving the cell nucleus undisturbed. The press uses an external hydraulic pump to drive a piston within a larger cylinder that contains the liquid sample. The highly pressurized sample is then squeezed past a needle valve. As the sample passes through the valve, the fluid experiences shear stress and decompression, causing cellular disruption.

    A French press is commonly used to break the resilient plasma membrane and cell walls of bacteria and other microorganisms for isolation of proteins and other cellular components. The disruption of cells in a French press generates ‘inside-out’ membrane vesicles which are required for many in vitro biochemical assays.

    • The FRENCH PRESS G-M™ matches the performance of traditional FRENCH PRESSES.
    • Old style Standard PRESSURE CELLS (40 kpsi; 35ml) can be used. Sold separately.

    The mixer mill MM 200 is a compact versatile benchtop unit, which has been developed specially for dry grinding of small amounts of sample.
    It can mix and homogenize powders in only a few seconds. It is also perfectly suitable for the disruption of biological cells as well as for DNA/RNA extraction.

    You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time.

    Application Examples

    Alloys, Animal Feed, Bones, Ceramics, Cereals, Chemical Products, Coal, Coke, Drugs, Glass, Grains, Hair, Minerals, Oil Seeds, Ores, Paper, Plant Materials…

    Product Advantages

    • Reproducible, efficient grinding, mixing and homogenization in seconds
    • Powerful grinding by impact and friction, up to 25 Hz for up to 20 samples per run
    • 9 SOPs can be stored
    • Wide range of accessories including various jar and ball sizes, adapter racks, grinding tool materials

    Function Principle

    The grinding jars of the MM 200 perform radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jars and pulverize it. Also, the movement of the grinding jars combined with the movement of the balls result in the intensive mixing of the sample.
    The degree of mixing can be increased even further by using several smaller balls. If several small balls are used (e.g. glass beads) then, for example, biological cells can be disrupted. The large frictional impact effects between the beads ensure effective cell disruption.

    Planetary Ball Mills are used wherever the highest degree of fineness is required. In addition to well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying. The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and therefore short grinding times.

    The PM 100 is a convenient bench top model with 1 grinding station.

    You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time.

    Application Examples

    Alloys, Bentonite, Bones, Carbon Fibres, Catalysts, Cellulose, Cement Clinker, Ceramics, Charcoal, Chemical Products, Clay Minerals, Coal, Coke, Concrete, Compost, Electronic Scrap, Fibres, glass…

    Product Advantages

    • Powerful and quick grinding down to nano range
    • Reproducible results due to energy and speed control
    • Suitable for long-term trials
    • 2 different grinding modes (dry and wet)
    • Optional pressure and temperature measuring system PM GrindControl
    • Wide range of materials for contamination free grinding
    • Safety Slider for safe operation
    • Perfect stability on lab bench thanks to FFCS technology
    • Innovative counter weight and imbalance sensor for unsupervised operation
    • Comfortable parameter setting via display and ergonomic 1-button operation
    • Automatic grinding chamber ventilation
    • 10 SOPs can be stored
    • Programmable starting time
    • Power failure backup ensures storage of remaining grinding time
    • Jars with O-type sealing for safe operation, pressure tight

    Function Principle

    The grinding jar is arranged eccentrically on the sun wheel of the planetary ball mill. The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2.

    The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces. The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies. The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill.

    Planetary mills with a single grinding station require a counterweight for balancing purposes. In the Ball Mill PM 100 this counterweight can be adjusted on an inclined guide rail. In this way the different heights of the centers of gravity of differently-sized grinding jars can be compensated in order to avoid disturbing oscillations of the machine.

    Any remaining vibrations are compensated by feet with some free movement (Free-Force Compensation Sockets). This innovative FFCS technology is based on the d’Alembert principle and allows very small circular movements of the machine housing that result in an automatic mass compensation. The laboratory bench is only subjected to minimal frictional forces generated in the feet.

    In this way the PM 100 ensures a quiet and safe operation with maximum compensation of vibrations even with the largest pulverization forces inside the grinding jars and therefore can be left on the bench unsupervised.
