SM 50 INTRODUCTION
Many laboratories face these challenges:
-
- Time losses due to complex cleaning and reassembly
- Sample losses caused by hidden residues in hard-to-reach areas
- Limited flexibility when processing various materials
- Risk of contamination that can distort analysis results
SM 50 tackles challenges:
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.
A SINGLE SOLUTION FOR EVERYTHING
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.
EVERYTHING IN VIEW
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.
STOP WASTING TIME
- The push-fit system allows rotor, sieves, cyclone and milling chamber to be removed without tools.
- For the first time, the milling chamber can be removed as well, making complete cleaning easy and significantly reducing machine downtime.
- EasyInspect hopper fully opens for inspection and cleaning, ensuring quick cleaning.
- No more hard-to-reach pipes or hoses – the SM 50 integrates the cyclone directly into the machine.
- Intuitive operation via touch display and push button, allowing effortless speed adjustments.
Up to 30 % time savings on cleaning with the Total Access Concept and push-fit components.
MULTIPLE OPTIONS FOR CLEANING AND OPERATION
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.
STOP LOSING MATERIAL
Up to 100 % sample recovery*
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.
STOP MANUAL PRE-CUTTING
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:
- Dense monoliths: Dog biscuits, roots, wood pieces
- Tough polymers: Plastic components, rubber compounds, children toys, household items
- Hard & brittle components: electronic parts, LN2 embrittled samples
STOP CONTAMINATION
Maximum safety, even with frequent sample material changes
- Cleaning on a new level: All grinding tools are easily accessible and can be reliably cleaned of persistent residues. For the first time, the milling chamber can be cleaned separately as well, further preventing cross-contamination from previous milled samples.
- The push-fit milling chamber is available in various materials, such as stainless steel for abrasion-resistant grinding or aluminum for standard applications as well as for grinding without heavy-metal contamination, allowing a flexible setup in one mill.
STOP COMPROMISING
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.
- 1.5 kW drive with variable speed for highly efficient size reduction.
- Maximum speed of 4,000 rpm for exceptional cutting performance
- Large 130 mm rotor diameter and depth of 48 mm for high impact power and fast sample throughput (comparable to large floor-standing cutting mills).
- Superior cutting speed of 27 m/s.
- 3 double acting cutting bars result in 18 cutting events per round and a specific cutting length of 864 mm per round for superior cutting efficiency.
- Optimized design reduces blockages and guarantees smooth operation
- Comprehensive and convenient door opening mechanisms with a pivoting handle.
WIDE RANGE OF ACCESSORIES FOR THE MOST FLEXIBILITY
For the SM 50 a wide range of accessories is available including
- Push-fit milling chamber of three different materials for standard applications, abrasive and corrosion-resistant applications, and for grinding without heavy-metal contamination.
- The integrated cyclone ensures complete sample recovery.
- Gravity chamber for grinding without cyclone, where the receptacle is placed directly underneath the machine so that the material falls in by gravity. Only suitable for applications requiring coarse pre-grinding of non-dusty materials.
- Parallel-section rotor and 3-disc rotor designed for processing materials ranging from soft to hard properties.
- 9 different sieve sizes from 10 mm down to 0.25 mm for standard application or for grinding without heavy-metal contamination.
- Collecting systems are available in 0.25 and 0.5 l capacities for glass collection, as well as a 3 l container.

FUNCTIONAL PRICIPAL
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.
