Modèle RS200 de Retsch

The Vibratory Disc Mill RS 200 is suitable for the extremely quick, loss-free and reproducible grinding of medium-hard, hard, brittle and fibrous materials to analytical fineness.
Grinding sets made from hardened chrome steel, tungsten carbide, agate and zirconium oxide permit a wide range of applications. The RS 200 is primarily used for sample preparation for spectral analysis.

Application Examples

cement, cement clinker, ceramics, coal, coke, concrete, corundum, glass, metal oxides, minerals, ores, plant material, silicates, slag, soils and many other materials

Function Principle

The Vibratory Disc Mill RS 200 comminutes by pressure, impact and friction. The grinding set is firmly attached to the vibration plate with a quick-action lever. The plate with the grinding set is subjected to circular horizontal vibrations.
The centrifugal force acting on the grinding rings in the dish results in extreme pressure, impact and frictional forces acting on the sample, producing analytical fineness in 1-3 minutes. The circular vibrations are produced by a frequency controlled 1.5 kW 3-phase motor.
A sensor recognizes the presence of agate grinding sets and automatically limits the speed to 700 min-1 to avoid damaging the agate. The cover of the noiseinsulated grinding chamber has a safety interlock and can only be opened when the mill is at a standstill.
