Weight (kg)210
Tariff902480 90
  • Suitable for quick, loss-free and reproducible grinding of medium-hard, brittle and fibrous materials to analytical fineness.
  • *Grinding Set must be ordered separately

Application Examples

  • Cement, cement clinker, ceramics, coal, coke, concrete, corundum, electronic components, glass, metal oxides, minerals, ores, plant materials, silicates, slag, soils.


  • reproducible results due to “Stabilised-Plane-Drive” (avoids tumbling of the grinding set)
  • variable speed 700 – 1,500 min-1
  • extremely short grinding time
  • agate and tungsten carbide recognition for automatic speed reduction
  • 10 SOPs can be stored
  • no sample loss thanks to optimum O-ring seal
  • wide range of materials for contamination free grinding
  • noise-insulated grinding chamber
  • quick-action grinding set clamping device for convenient and safe tightening
  • safety interlock
  • easy 1-button operation with coloured graphics display
  • new carry handle
  • new ergonomic design, heavy grinding sets can be inserted closer to the user´s body and slided into the machine, leading to less strenuous laboratory work especially for high throughput users

Principle of Operation

  • The Vibrating Disc Mill reduces by 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 recognises the presence of agate grinding sets and automatically limits the speed to 700 min-1 to avoid damaging the agate.
  • The cover of the noise-insulated grinding chamber has a safety interlock and can only be opened when the mill is at a standstill.
