Risk of explosion or fire
Potentially explosive atmosphere
 On account of its design, the device is not suitable for use in potentially
explosive atmospheres.
 Do not operate the device in a potentially explosive atmosphere.
CAUTION
C8.0006
Danger of personal injury
Hazardous sample material
 Depending on the dangerous nature of the sample material necessary
measures must be taken to rule out any danger of personal injury.
 Observe the material safety data sheets of the sample material.
CAUTION
C9.0004
Risk of explosion or fire
Changing sample properties
 The properties and therefore also the hazardousness of the sample can
change during the grinding process.
 Do not use any substances in this device which carry the risk of
explosion or fire.
 Observe the material safety data sheets of the sample material.
CAUTION
C10.0010
Chemical reactivity
Changing sample properties
 The properties and therefore also the chemical reactivity of the sample
can change during the grinding process.
 Do not use any substances in this device which carry the risk of
increasing chemical reactivity during the grinding process.
 Observe the material safety data sheets of the grinding material.
This Rotor Beater Mill of the Retsch GmbH is a laboratory device. It is used for the batch-wise
or continuous coarse and fine grinding of dry, soft to medium-hard materials such as soils,
bentonite, chemical products, fertilizers, drugs, feed pellets, spices, gypsum, graphite, resins,
coal, coke, herbs, plastics, food, plant parts, pharmaceutical products, powder lacquer, rice,
seeds, salts, sugar and many other substances. The device allows for a particularly effective
grinding of heterogeneous material mixtures. The analytical fineness is usually achieved in a
single step. Thereby, the grinding material is hardly heated, so that the SR 300 is also suitable
for temperature-sensitive materials. Depending on the mesh size of the sieve and the fracture
properties of the grinding material, the achievable final fineness can be < 50 µm.
