| Description | Cutting mills are suitable for the grinding of soft, medium-hard, tough, elastic, fibrous, and heterogeneous mixes of products. The new Cutting Mill SM 300 excels especially in the tough jobs where other cutting mills fail.
The high torque of the new 3 kW drive with RES technology (additional Cutting mills are suitable for the grinding of soft, medium-hard, tough, elastic, fibrous, and heterogeneous mixes of products. The new Cutting Mill SM 300 excels especially in the tough jobs where other cutting mills fail.
The high torque of the new 3 kW drive with RES technology (additional flywheel mass) allows for an exceptionally effective preliminary size reduction of heterogeneous mixtures, such as waste or electronic components. Analytical fineness is often achieved in one working run.
The cutting mill is used successfully for a great variety of materials. The sample is only moderately warmed up during the grinding process so that the mill is perfectly suitable for grinding temperature-sensitive materials. Another innovation is the wide, freely selectable speed range from 700 to 3,000 min-1. In combination with the wide choice of bottom sieves, hoppers and collecting vessels, the mill can be easily adapted to varying application requirements.
Features - Powerful size reduction thanks to 3 kW drive with high torque and RES technology
- Perfect adaptation to application requirements by variable speed from 700 to 3,000 min-1
- Optimum cutting effects thanks to double acting cutting bars
- Quick and easy cleaning due to fold-back hopper, smooth surfaces and push-fit rotor
- Defined final fineness due to bottom sieves with aperture sizes from 0.25 - 20 mm
- Wide range of accessories including various hoppers, collection systems, rotors and sieves
- Highest safety standards due to engine brake, central locking device, electronic safety check and base frame

It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved.
The The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved.
The liquid nitrogen is continually supplied from an autofill system in the exact amount required to keep the temperature at –196 °C. The CryoMill's versatility makes it the ideal grinder for sample quantities up to 20 ml.- powerful grinding by impact and friction with up to 30 Hz
- pulverization of two samples down to 5 micron
- The user never comes into direct contact with LN2 which ensures a high degree of operational safety
- adapter for keeping 2 ml plastic tubes or 2 ml steel tubes available
- special jar zirconium oxide available for heavy-metal free grinding
- suitable forgrinding in interval
- 3 different grinding modes (dry, wet or cryogenic)
- memory for 9 SOPs
- Screw-Top jars
