| 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 mixes and homogenizes powders and suspensions with a frequency of 30 Hz within seconds – unbeatably fast and easy to operate. It is also very useful for The Mixer Mill MM 400 is a true multipurpose mill designed for dry, wet and cryogenic grinding of small volumes up to 2 x 20 ml. It mixes and homogenizes powders and suspensions with a frequency of 30 Hz within seconds – unbeatably fast and easy to operate. It is also very useful for mechanosynthesis applications with RAMAN readyness and a grinding time up to 8 h. It is also the most suitable instrument for biological applications such as cell disruption for nucleic acids or protein extraction.

... Read More | The mixer mill MM 500 control is a unique compact, versatile bench-top unit which has been developed to work in a temerature range from -100°C to + 100°C and thus either cool samples or heat them up while grinding. It is used for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material The mixer mill MM 500 control is a unique compact, versatile bench-top unit which has been developed to work in a temerature range from -100°C to + 100°C and thus either cool samples or heat them up while grinding. It is used for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material within seconds. With a maximum frequency of 30 Hz, it generates enough energy to produce particles in the nanometer range. The robust high-performance drive makes the mill suitable for long-term grinding processes up to 99 hours. Hence, the MM 500 control is the first mixer mill in the market to provide a real alternative to grinding in a planetary ball mill with special cooling options and with more comfortable handling - powerful grinding by impact and friction with up to 30 Hz
- pulverization of two samples down to the nanometer range < 0.1 micron
- multi-cavity jars 2x 25 ml or 4 x 10 ml available
- adapter for keeping 2 ml plastic tubes or 2 ml steel tubes available
- suitable for long-term grinding processes up to 99 h
- suitable for mechanochemistry applications
- 3 different grinding modes (dry, wet or cryogenic)
- memory for 12 SOPs and 4 program cycles
- Screw-Lock jars, pressure-tight up to 5 bar
GrindControl to measure pressure and temperature available - grinding under inert gas (optional)
- jar design allows full use of the volume, also for wet grinding
- jars remain conveniently clamped for periodic sample extraction or visual checks
