The nature of the oscillations of the cup provides a run-in of the roller along the ring, as well as a run-in of the ring along the inner wall of the cup. The shape of the grinding organs provides circulation of the material inside the cup.
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.
The end switch prevents the grinder from starting with cover open.
ORIGINAL DRIVE SYSTEM
The use of elastic lobe clutch reduces the vibration transmitted to the bearing surface.
QUALITY SPARE PARTS
The cup is made of tool steel (AISI 01, DIN 150Cr14, 9XC). A zirconium dioxide cup is available on request. Polishing of the cup, lid, ring and roller minimizes contamination of the sample with particles from previous samples.
NO SAMPLE CONTAMINATION
The use of zirconium dioxide cup allows avoiding the contamination of the sample by metal particles of the grinder working bodies.
COMPATIBLE WITH CONTROL PANEL
The control panel is designed to start and stop the equipment and provides:
DESCRIPTION OF THE DEVICE
In VG 1 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.
A platform with a cup fastener and a cup assembled (a cup, a lid, a ring, a roller) is mounted on the platform through the springs. Rotation from the electric motor is transmitted through a belt drive to a drive shaft, which is mounted on a plate in the bearing assembly. From drive shaft the torque is transmitted through an elastic lobe clutch coupling to the debalance fixed on the axis of the platform.
The folding cover of VG 1 is designed to insulate the noise and to prevent access to the vibrating parts of the grinder.
VG 1 platform with the cup fixed on it performs circular oscillations in the horizontal plane. Due to this, the ring runs on the walls of the cup, and the roller — on the walls of the ring. The material is grinded between the walls of the cup and the ring, between the roller and the ring, and also between the lower ends of the roller, ring and the bottom of the cup; the upper ends of the ring, roller and lid.
