Vibrating grinders are designed to comminute samples to a finely dispersed state in intermittent operation.
In a vibrating grinder, comminution occurs by means of abrasion – simultaneous compressive and shear strain of material particles between the crushing bodies and the cup walls.
The grain size of the ground material depends on the grinder operating time, the initial grain size and the physical properties of the material, as well as the cup loading volume.
The VG 1 vibrating grinder is designed for comminution in intermittent operation of one sample with volume from 20 to 50 cm3, while the VG 3M vibrating grinder is designed to handle three such samples simultaneously.
The VG 6 vibrating grinder is designed for simultaneous comminution of six small (up to 5 cm3) samples.
