Cutting mill
Encyclopedia
Cutting mills are mechanical devices commonly used in laboratories
for the preliminary size reduction of soft, medium-hard, fibrous and tough material
s.
A rotor
inside the mill revolves at high speed. The rotor is equipped with special cutting plates which comminute the sample material. Different rotor geometries make mills adaptable to different material properties (medium-hard, soft, fibrous or elastic materials). Such mills are suitable for reducing rubber, leather, plastics, grains, dried meat, bones, vegetation and other substances.
In elemental analysis
, cutting mills should be used with care, since they can contaminate finely-reduced samples with metal

Laboratory
A laboratory is a facility that provides controlled conditions in which scientific research, experiments, and measurement may be performed. The title of laboratory is also used for certain other facilities where the processes or equipment used are similar to those in scientific laboratories...

Material
Material is anything made of matter, constituted of one or more substances. Wood, cement, hydrogen, air and water are all examples of materials. Sometimes the term "material" is used more narrowly to refer to substances or components with certain physical properties that are used as inputs to...

Turbine
A turbine is a rotary engine that extracts energy from a fluid flow and converts it into useful work.The simplest turbines have one moving part, a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades, or the blades react to the flow, so that they move and...

Metal
A metal , is an element, compound, or alloy that is a good conductor of both electricity and heat. Metals are usually malleable and shiny, that is they reflect most of incident light...
