The Vibratory Disc Mill RS 200 is used for rapid pulveriza- reproducible without loss, medium-hard materials, hard, brittle and fibrous materials to analytical fineness. The new type of drive "Stabilized-Plane-Drive", the mill is characterized by quiet, smooth and secure, even with heavy grinding sets and at maximum speed.

Due to its solid construction, the RS 200 has proven particularly in the building materials sector (cement), in geology, mineralogy, metallurgy and in power plants.

Like the RS 200 offers very little time to achieve extremely fine, it is particularly suitable for the preparation of samples for spectral analysis.

Examples of Application
concrete, ceramics, coal, cement, clinker, coke, electronic components, corundum, minerals, ores, plant parts, metal oxides, slag, silicates, floors, glass, ...


Product benefits derived
  • reproducible grinding results through training stabilized in a plane
    "Stabilized-Plane-Drive" (prevents swinging of the grinding set)
  • automatic closing of the lid
  • variable rotational speed from 700 to 1500 rev / min
  • very short milling time
  • agate recognition for automatic speed reduction rotation
  • can store 10 programs (SOP)

Operating principle
The Vibratory Disc Mill RS 200 crushed by pressure, impact and friction. The milling insert is fixed to the vibration plate with a quick-release lever. The tray with the grinding set is circular horizontal vibrations. The grinding rings in bowl practice, due to these movements, vibration, pressure effects, percussion and extreme friction on the sample material. Circular vibrations are generated by a vibrating control with a three-phase motor 1.5kW regulated frequency. The unique training Stabilized-Plane-Drive-type guarantees constant direction of movement in a single plane, thereby effectively preventing any unwanted movement or rocking of the grinding bowl. A sensor recognizes the presence of agate trim and limits the speed to 700 rev / min in order to avoid possible damage to the fragile material.
