 VGE is not intended for grinding of humid, greasy or prone to agglomeration materials.

ADVANTAGES

GRINDING EFFICIENCY

Platform oscillation mode stimulates the circulation of material inside the cup.

The oscillation amplitude of the platform (16 mm) provides high grinding performance.

 EASY MAINTENANCE

Folding cover for quick access to the cup.

Cup fastener with adjustable latch.

 EFFECTIVE NOISE INSULATION

Soundproofing lining inside the cover and on the entire inner surface of the casing.

 OPERATIONAL SAFETY

The end switch prevents the grinder from starting with cover open.

DRIVE SHAFT

Durable drive shaft transfers torque from the electric motor to the eccentric weight of the platform.

WIDE RANGE OF SAMPLE VOLUMES

There is a possibility of grinding samples from 250 to 750 ml in a standard cup.

BUILT-IN TIMER

The timer allows setting the operating time and automatically stops the grinder.

QUALITY SPARE PARTS

The cup is made of tool steel (AISI 01, DIN 150Cr14). Polishing of the cup, lid and roller minimizes contamination of the sample with particles from previous samples.

The roller resource is increased due to possibility of its 180° turn.

SAFE CUP FIXATION

The cup fastener is equipped with a locking latch that excludes spontaneous opening of the cup.

CONVENIENT SAMPLE UNLOADING

The cup lifting device and the hook for the roller provide the operating convenience.

DESCRIPTION OF THE DEVICE

In VGE vibrating grinder comminution occurs due to abrasion — simultaneous compression and shear of the material. The product particle size depends on the hardness of the material and the comminution time.

The platform with the cup fastener fixed on it and assembled cup (cup itself, lid and roller) is mounted on the frame through the springs. The torque from the electric motor is transmitted through the drive shaft to the eccentric weight on the axis of the platform.

The folding cover of VGE is designed to insulate the noise and to prevent access to the vibrating parts of the grinder.

OPERATING PRINCIPLE

VGE platform with the cup fixed on it performs circular oscillations in the horizontal plane. Due to this, the roller makes circular movements along the walls of the cup. The material is grinded between the roller, the bottom and the walls of the cup. The built-in timer allows to set the comminution time in the range from 1 to 30 minutes. The time needed is to be determined empirically and depends on the material hardness and the volume of the sample.
