| Code | LAG470 |
| Weight (kg) | 210 |
| Tariff | 902480 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.
Advantages
- 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.
