Retsch Rotor Beater Mill SR 300
The Rotor Beater Mill SR 300 is suitable for coarse and fine size reduction. It can process dry, soft, medium-hard, organic and inorganic substances. For increased sample discharge and for processing heat-sensitive samples, an optionally available cyclone unit can be used instead of the gravity outlet.
PRODUCT ADVANTAGES
- wide range of accessories including various feeding systems, rotors and sieves
- defined final fineness due to bottom sieves with aperture sizes from 0.08 - 10 mm
- optional grinding inserts 180° for grinding of hard-brittle materials by additional impact
- gravity outlet with 5l or 30 L collecting vessel for batchwise collection of larger sample quantities
- optionally available cyclone unit with 0.25 - 0.5 - 1 - 2 - 5 or 30 liters collecting vessel
- optional distance rotor to reduce frictional heat
- adjustable speed for different applications
- removable hopper for easy cleaning
- easy cleaning thanks to exchangeable push-fit grinding insert, rotor and cassette
