Language:

Cutting mills are suitable for the grinding of soft, medium-hard, tough, elastic, fibrous, and heterogeneous mixes of products. Thanks to the powerful 3 kW drive with high torque and RES technology, the Cutting Mill SM 300 excels especially in the tough jobs where other cutting mills fail. This mill allows for perfect adaptation to application requirements by variable speed from 100 to 3,000 min-1. A range of bottom sieves with aperture sizes from 0.25 - 20 mm is available, ensuring a defined final fineness. 

"It is a very robust mill that allows us to homogenize samples with a very uniform particle size according to the sieve used and very easy to use. Since it is a very robust equipment, as it is made to last, definitely I would recommend."

"This mill is the work horse of the department. It can handle almost everything you want to put through it. Easy to take apart and clean. I have worked with other mills in the past and this one is by far the best."

"Before our acquisition of the SM 300, we were using a VitaMix to convert structured components into powder. Of course, that took ages for larger batches of material. Now, with the mill, we are able to save on time and energy. It is a must purchase for any business that needs to cut, powder, mill, eviscerate, or otherwise reduce large particles in any way."

Ideal for light & heat-sensitive materials

Instead of the gravity outlet, an optionally available cyclone separator can be connected to the SM 300. The use of the cyclone is advantageous, for example, for light and heat-sensitive samples. 

  • Increased throughput
  • Improved sample discharge from the grinding chamber
  • Efficient cooling of sample and cutting tools
  • Collecting vessels with 0.25 - 0.5 - 1 - 2 - 5 and 30 liters are available for the cyclone unit

Double acting cutting bars

Double acting cutting bars

The SM 300 is equipped with double acting cutting bars which substantially increase the number and effectiveness of the cutting events. The parallel section rotor, for example, generates 18 cutting events per rotation.

Convenient operation

Operation of the SM 300 is exceptionally simple and safe. The push-fit rotor and bottom sieves can be easily removed without tools. A safety switch prevents the mill from being started with the door open. An electronic safety check ensures that the door cannot be opened when the motor is running.

Quick and easy cleaning

The hopper can be folded back to get full access to the grinding chamber which, in combination with the smooth surfaces, greatly facilitates cleaning the mill. So does the design of the bottom sieves which reduces trapping of sample pieces to a minimum.

316L Stainless Steel Version foodGrade

For applications like small scale production of food or cosmetics, the SM 300 is available in a stainless steel 316L foodGrade version which meets the guidelines of the food and pharma industry. It is equipped with a long-stock hopper for easy feeding of materials like cannabis plant parts. All parts in contact with the sample are made of 316L in this configuration. Optionally, the rotor blades and the cutting bars are made of a FDA-certified stainless steel which is less prone to wear under constant stress than 316L.

The unit can be equipped with an optional cyclone and a large 30 l receptacle (both stainless steel 316L) for collecting large sample amounts. Smooth surfaces lead to almost 100% sample recovery and easy cleaning.

Rotor Types

Rotor Types

A parallel section rotor, a 6-disc rotor and a V-rotor are available in stainless or heavy-metal-free steel for optimum adaptation to sample properties. 

Hopper Types

Hopper Types

The SM 300 can be equipped either with the universal hopper, which is suitable for most samples, or the long-stock hopper which is specially designed for long samples.

Bottom Sieves

Bottom Sieves

The bottom sieves with trapezoid or square holes are made of stainless steel or heavy-metal-free steel.

Brukseksempler Torrefaction & bio-coal

Torrefaction is a thermochemical process carried out in the absence of oxygen to cause the partial decomposition of biomass. Water and volatiles are released from the biomass to leave a solid, dry material known as bio-coal. For some applications, bio coal can be used to replace traditional fossil fuels, thus helping to reduce CO2 emissions.

In this video, both RETSCH cutting mill SM 300 and the CARBOLITE GERO rotating tube furnace TSR have been used as a part of a torrefaction process to create bio-coal fuel. 

The Verder Scientific companies provide solutions to support your process every step of the way, from sample preparation and analysis, to heat treatment, and more.

Høyytelses-kuttemølle SM 300 Virkemåte

Kuttemøllen SM 300 maler med kutte- og skjærekrefter. Materialet kommer i kontakt med rotoren og blir kuttet mellom denne og kuttelister montert i malekammer. Rotor er også lagret i dør, slik av skjevhet i aksling forhindres ved hard belastning. På 6-platerotoren er vendbare kutteplater i hardmetall montert i spiralform. Parallell kutte rotoren gir kraftfulle snitt i materialet. Ved hjelp av en ekstra svingmasse på rotoraksling oppnåes det en kraftig ytelse, som ellers kun blir oppnådd i motorer med dobbelt så stor effekt. Ved hjelp av det justerbare turtallet fra 100 - 3000 omdreining per minutt kan SM 300 enkelt stilles inn til å håndtere den aktuelle oppgaven.
