THE PRODUCT IN FOCUS
The SM 50 revolutionizes laboratory workflows and solves multiple problems at once. With its innovative design featuring a removable milling chamber, the SM 50 simplifies cleaning and reassembly, saving up to 30 % time.
At the same time, the powerful benchtop cutting mill guarantees almost 100 % sample recovery with contamination-free sample preparation.
PERFORMANCE & OPERATION
The new SM 50 revolutionizes laboratory workflows and solves multiple problems at the same time. With its innovative design featuring a removable milling chamber, the SM 50 simplifies cleaning, saving up to 30 % process time. At the same time, the unrivaled powerful benchtop cutting mill with a single phase power plug allows up to 100 % sample recovery* and contamination-free sample preparation.
The SM 50 is the world’s most powerful benchtop cutting mill with a standard one phase power plug. Its 1.5 kW motor drives a large rotor, delivering impressive high-speed cutting power. The max. speed is 4,000 rpm and can be adjusted to suit various applications.
The EasyInspect hopper operates on a batch-wise feeding system and can process large sample pieces up to 50 mm with ease. The compact powerhouse features an internal cyclone system, ensuring effortless and efficient processing of various materials.
Sieves with apertures from 0.25 mm to 10 mm allow a final fineness of less than 250 µm, depending on the feed material. A two-step grinding process allows fine particles to be produced by first using a large aperture sieve, followed by a finer one. The design supports high throughput with large sieve areas of 48 mm x 120 mm.
World innovation: When opening the machine door, the front of the hopper swings out to the side, providing full visibility inside. The Total Access Concept ensures easy inspection and cleaning of all sample-contacting components.
Up to 30 % time savings on cleaning with the Total Access Concept and push-fit components.
Surface cleaning: full access to mill interior, including hopper, with door open for inspection and cleaning with brush, vacuum or compressed air
Intense Cleaning: Comprehensive external cleaning of all grinding tools, including sieve, rotor, cyclone and grinding chamber, all removable without tools using a push-fit system
Parallel cleaning: If a second grinding set is available, samples can be processed directly one after another, thanks to the push-fit grinding tools, including the push-fit milling chamber.
Compared to milling without cyclone technology, the recovery of sample material is significantly improved. The cyclone technology efficiently transports the sample into the receptacle with no dust release and minimal sample residue left in the mill.
The integrated cyclone eliminates the need for connecting elements such as pipes or hoses and minimizes distances and surface areas.
The batchwise feeding of the hopper concept serves as a flow control gate and optimizes the grinding performance and separation efficiency of the cyclone.
Cyclone technology, small distances and minimized surface areas optimize the material flow in the mill and enables up to 100 % sample recovery.*
The compact EasyInspect hopper allows processing of large sample pieces without pre-cutting.
The exceptionally large grinding chamber allows large samples to be fed, as does the hopper design for batch feeding of samples up to 50 mm. The power and technical design of the SM 50 makes it easy to process a wide range of materials, including:
Animal Feed
Plastic Toys
Roots
Maximum safety, even with frequent sample material changes
Push-fit milling chamber can be cleaned outside the machine using e.g. water.
The SM 50 expertly merges the compactness of benchtop-mills with the high-capacity performance of floor-standing mills. Unlike other benchtop models, it can grind large monolithic samples, thanks to its expansive hopper and chamber volume. Precision. Power. Performance. Nothing less than exceptional results. And there are many more reasons to choose the new SM 50.

Discover the key functions of the SM 50
Remove the push-fit milling chamber for cleaning outside the mill and quick setup changes. A choice of chamber materials helps match the grinding tools to the sample and its contamination requirements.
Feed batches of up to 200 mL or individual sample pieces up to 50 mm. The one-hand plunger controls sample flow, while a flap guides bulky material into the milling channel. The hopper opens for inspection and cleaning.
The compact cyclone sits inside the mill housing to keep the sample path short and limit material loss. Its lid and body separate for cleaning. A GL55 connection accepts 250 mL or 500 mL glass bottles, or a 3 L receptacle with an adapter.
Different tasks, different users
In contract laboratories or academic institutions, many people use the same laboratory grinder for a wide variety of samples. It can happen that feathers are ground today and textiles or completely different sample types tomorrow.
Optimized for different sample tasks in a row
The SM 50 makes it easier to switch between sample types. The milling chamber, rotor, sieve and integrated cyclone can be removed without tools for cleaning outside the mill. With a second grinding set, the next sample can be processed while the used components are cleaned, reducing downtime between tasks and helping prevent carryover from the previous sample.
Grinding of small sample quantities
When sample material is limited, minimizing losses during grinding and collection matters. The SM 50's integrated cyclone provides a short path from the milling chamber to the collecting vessel, with no connecting hoses or pipes where material can remain. Optional 250 mL and 500 mL glass collecting bottles support smaller collection volumes, and the accessible grinding components make residual material easier to inspect and recover.
The Cutting Mill SM 50 utilizes cutting and shearing forces to achieve size reduction. Samples are fed in batches through the EasyInspect hopper and transported to the milling chamber using a plunger. Within the chamber, the sample is comminuted between rotor blades and stationary double-acting cutting bars. The 3-disc rotor is equipped with spirally arranged reversible hard metal plates that cut sequentially, while the parallel section rotor delivers a robust cutting action for efficient comminution.
Cyclone technology aids in transferring material from the milling chamber to the receptacle, supported by specific air vents that optimize sample discharge. With a variable speed range from 500 to 4,000 rpm, the SM 50 is easily adaptable to a variety of application requirements.
TOOLS & CONFIGURATION
Choose a parallel-section rotor or a 3-disc rotor to suit the material and preparation task.
The short collection path helps transfer ground material to the receptacle with minimal residue. The cyclone can be removed for cleaning.
Nine sieve apertures from 0.25 to 10 mm support different fineness targets. Options are available for standard and heavy-metal-free preparation.
