| Description | The Rotor Beater Mill SR 300 is suitable for coarse and fine size reduction, either in batches or continuously. It can process dry, soft, medium-hard, organic and inorganic substances.
Its high speed in comparison to the SR 200 allows a significantly higher throughput and fineness.
The SR 300 isThe Rotor Beater Mill SR 300 is suitable for coarse and fine size reduction, either in batches or continuously. It can process dry, soft, medium-hard, organic and inorganic substances.
Its high speed in comparison to the SR 200 allows a significantly higher throughput and fineness.
The SR 300 is intended for universal use: from sample preparation in laboratories up to preparing sample batches in pilot plants or production facilities. The grinding chamber, the feed hopper and the material inlet are completely made from high quality stainless steel.
Features
- Suitable for batchwise operation of larger quantities
- Central locking device
- Wide range of accessories including various collection and feeding systems, rotors and sieves
- High final fineness
- Exchangeable grinding and sieve inserts
- Grinding chamber, feed hopper and material inlet and outlet of stainless steel
- Optional grinding inserts 180° for grinding of hard-brittle materials by additional impact
- Optional distance rotor to reduce frictional heat
- Removable hopper for easy cleaning
- Motor brake
- Defined final fineness due to bottom sieves with aperture sizes from 0.08 - 10 mm

Read More | The mixer mill MM 500 nano is a compact, versatile bench-top unit which has been developed specially for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material within seconds. With a maximum frequency of 35 Hz, it generates enough energy to produce particles in the nanometer range. The The mixer mill MM 500 nano is a compact, versatile bench-top unit which has been developed specially for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material within seconds. With a maximum frequency of 35 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 nano is the first mixer mill in the market to provide a real alternative to grinding in a planetary ball mill – with more comfortable handling and less warming effects. - powerful grinding by impact and friction with up to 35 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

The instrument runs steadily and smoothly, even with heavy grinding sets, at maximum speed thanks to the new Stabilized-Plane-Drive.
With its robust design, the RS 200 has proven to be ideal for use in the building materials sector (cement), in geology, mineralogy, metallurgy and in power plants. Due to the high end fineness and speed the RS 200 is the perfect mill when it comes to preparing samples for spectral analysis.
Features - Reproducible results due to "Stabilized-Plane-Drive" (avoid tumbling of the grinding set)
- Safety interlock
- Variable speed 700 - 1,500 min-1
- Extremely short grinding time
- Agate recognition for automatic speed reduction
- 10 SOPs can be stored
- No sample loss thanks to optimum o-ring seal
- Wide range of materials for contamination free grinding
- Noise-insulated grinding chamber
- Quick-action grinding set clamping device
