    The Jaw Crusher BB 100 is used for the rapid, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials.

    Its variety of materials offered including heavy-metal free steel, its efficiency and safety makes this Jaw Crusher ideal for sample preparation in laboratories and industrial plants.

    Application Examples

    Alloys, Basalt, Cement Clinker, Ceramics, Chamotte, Coal, Coke, Construction Materials, Feldspar, Glass, Granite, Minerals, Quartz, Ores, Oxide Ceramics, Rocks, Silicon, Slag, …

    Product Advantages

    • Excellent crushing performance
    • Wide range of materials for contamination free grinding
    • Wear compensation with zero-point adjustment
    • Continuous gap width setting
    • Overload protection
    • No-rebound feed hopper with quick-release clamp
    • Brake motor with safety switch
    • Easy-to-clean crushing chamber
    • Continuous grinding
    • Connector for dust extraction

    Function Principle

    The BB 100 is a robust and powerful forced-feed Jaw Crusher. The feed material passes through the no-rebound hopper and enters the crushing chamber. Size reduction takes place in the wedge shaped area between the fixed crushing arm and one moved by an eccentric drive shaft. The elliptical motion crushes the sample which then falls under gravity. As soon as the sample is smaller than the discharge gap width, it falls into a removable collector within the Jaw Crusher. The continuous gap width setting with scale ensures optimum size reduction in accordance with the set gap width.

    • Special version for grinding semi-conductor materials

    Function Principle

    The Jaw Crusher BB 500 is a robust and powerful forced-feed crusher. The feed material passes through the no-rebound hopper and enters the crushing chamber.

    Size reduction takes place in the wedge-shaped area between the fixed crushing arm and one oscillating with high frequency. This motion ensures a consistent gap width in the stroke cycle so that the sample is crushed to the set fineness in one working step. Two massive flywheels transmit high impulse forces to the crushing jaws. The innovative design permits using both sides of the jaws thanks to a 180° rotation.

    As soon as the sample is smaller than the discharge gap width, it falls into a removable collector. The continuous gap width setting with scale ensures optimum size reduction in accordance with the set gap width.

    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.

    Applications: Preliminary and Fine Grinding

    The DM 400 is the new comfort model for fine grinding of medium-hard, hard and brittle materials down to 0.05 mm. This model is based on the well-proven DM 200 but offers improved safety features due to the automatic locking of the collecting vessel and grinding chamber, as well as particularly convenient operation thanks to the motor-driven grinding gap adjustment with digital gap display. The clearly structured display shows all grinding parameters.

    Thanks to its robust design, the Disc Mill DM 400 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 400 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,

    Function Principle

    In the DM 400 the feed material enters the dustproof 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 incremental adjustable and can be motor-driven adjusted during operation in the range between 0.1 and 5 mm.
