ADVANTAGES

GRINDING EFFICIENCY

Two types of work surfaces are combined in the design of DG 65 discs: wedge-shaped (for preliminary comminution) and flat (for fine grinding).

NO SAMPLE CONTAMINATION

DG 65 discs are made of silicon carbide, loading funnel and collecting container are made of polyamide. This allows avoiding the contamination of the sample by metal particles of the grinder working bodies.

EASY MAINTENANCE

The bearing assembly is lubricated through a grease nipple. Easy adjustment of the V-belt drive.

 LABORATORY APPLICATION

Due to its small size and low energy consumption, DG 65 is suitable for use in laboratories.

CONVENIENT ADJUSTMENT

The adjustment device located next to the grinding chamber allows precise setting the gap between the discs. It is possible to set a minimum gap while the grinder is operating. A lock nut provides reliable fixation of the gap setting.

EASY CLEANING

Hinged cover and eccentric clamp provide easy access to the grinding chamber for sample unloading and grinder cleaning.

COMPATIBLE WITH CONTROL PANEL

The control panel is designed to start and stop the equipment and provides:

  • automatic power off when exceeding the maximum current value or short circuit;
  • protection of the operator from electric shock;
  • motor overload protection.

QUALITY SPARE PARTS

Moving and fixed discs are made of silicon carbide SiC (Mohs hardness more than 9). Loading funnel and collecting container are made of polyamide.

DESCRIPTION OF THE DEVICE

In DG 65 Disc grinder comminution occurs due to abrasion — simultaneous compression and shear of the material. The particle size of the final product is determined by the gap between the disks (discharge slot).

The structure of the grinder includes: a loading funnel, a hinged cover, moving and fixed disks, a housing, a collecting container and an electric motor.

The working bodies of DG 65 are two discs: a moving one mounted on the drive shaft and a fixed one mounted on the hinged cover. Inside the housing there is a collecting container. The discharge slot is set using the scale of adjusting device. The torque from the electric motor is transmitted through the V-belt drive to the drive shaft.

OPERATING PRINCIPLE

The initial material is fed into a loading funnel, from where it enters the working cavity between the disks through an opening in the center of the fixed disk. As a result of the action of centrifugal forces, the particles of the material move from the center to the edges of the disks, gradually grinding.

Two types of working surfaces are combined in the design of DG 65 discs: cone (for preliminary comminution) and flat (for fine grinding). The particle size of the final product is determined by the gap between the disks (discharge slot).

The stream of crushed particles coming from the gap between the disks enters the collecting container.

Moving and fixed discs wear evenly during operation. When the direction of disc rotation changes, the grinding efficiency does not decrease.
