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.

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
Healthy nutrition is the basis for a happy life. Our food should combine enjoyment and health. To achieve this, it is important that our food is free from harmful substances and that we have precise knowledge of its composition. The quality of agricultural products is tested in environmental and food laboratories.
Grinding of small sample quantities
What do your child’s carefree play and your dog’s health have to do with the food grinder SM 50? Product safety is essential in many areas, be it children’s toys or animal feed. Manufacturers and retailers must ensure that their products do not contain any ingredients that are harmful to health.
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.
