Vibratory Disc Mill (Net weight - 225 kg (without grinding set))

No grinder can beat the speed of a Vibratory Disc Mill when it comes to preparing samples for spectral analyses Vibratory Disc Mill (Net weight - 225 kg (without grinding set)) is ideally suited for fast and reproducible pulverization of hard, brittle and fibrous sample materials to analytical fineness.

The Vibratory Disc Mill (Net weight - 225 kg (without grinding set)) runs steadily and smoothly, even with heavy grinding sets and at maximum speed thanks to its powerful Stabilized-Plane-Drive. It achieves grind sizes between 20 and 100 microns within seconds and with excellent reproducibility.

FUNCTIONAL PRINCIPLE

The Vibratory Disc Mill (Net weight - 225 kg (without grinding set)) comminutes by pressure 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 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.

• Exceptionally safe and simple handling
• Operation and handling of the Vibratory Disc Mill (Net weight - 225 kg (without grinding set)) and its grinding sets is convenient and ergonomic. The grinding jars are equipped with carry handles which facilitate transport of the heavy jar to the mill where it is slid on a rail into its grinding station. The clamping device allows for safe fastening of the jar with less force; a sensor checks its correct position.
