ADVANTAGES

GRINDING EFFICIENCY

Two types of work surfaces are combined in the design of DG 175M discs: wedge-shaped (for preliminary comminution) and flat (for fine grinding).

 EASY MAINTENANCE

The bearing assembly is lubricated through a grease nipple.

 OPERATIONAL SAFETY

The end switch prevents the grinder from starting with grinding chamber open.

COLLECTING CONTAINER

DG 175M is equipped with the quick-detachable collecting container of 1.7 liters.

LABORATORY APPLICATION

Due to its small size and low energy consumption, DG 175M is suitable for use in laboratories.

CONVENIENT ADJUSTMENT

The adjustment device is located next to the grinding chamber. It is possible to set a minimum gap between the discs while the grinder is operating.

EASY CLEANING

There are no gaps between the fixed disk and the folding chamber. Between the moving disk and the housing there is a gap for cleaning and blowing residual material off.

BUILT-IN CONTROL PANEL

The built-in control panel is designed to start and stop the grinder and provides:

  • automatic shutdown when a power surge or short circuit;
  • motor overload protection.

FOLDING GRINDING CHAMBER

The folding grinding chamber provides quick access to the moving and fixed disks for cleaning or replacing them.

QUALITY SPARE PARTS

The DG 175M disks are made of cast iron GJN-HV600 (XCr14) or steel UNS J91109. Moving disc and fixed disc are interchangeable.

The grinder can also be equipped with tungsten carbide inserts discs, which significantly increase disks resource.

COMPATIBILITY WITH VIBRATORY FEEDER

Supplement DG 175M with vibratory feeder VG 1 provides:

  • increase in output up to 20%;
  • reduction of disk wear;
  • reduction of dusting;
  • facilitation of the operator work.

DESCRIPTION OF THE DEVICE

In DG 175M disc grinder comminution occurs due to abrasion — simultaneous compression and shear of the material.

The structure of the grinder includes: a folding grinding chamber with loading and discharge funnels, a collecting container, moving and fixed disks, a housing with a drive shaft, a base and an electric motor.

The particle size of the final product is determined by the gap between the disks (discharge slot). The gap between the disks is adjusted by moving the shaft with the moving disk in the axial direction.

The surface of the disks on the periphery is flat and near the center it has a complex wedge-shaped form. The selected dimensions and angles of inclination of the troughs and teeth provide high grinding efficiency and reduce the load on parts and assemblies during grinding.

OPERATING PRINCIPLE

The 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. The stream of crushed particles coming from the gap between the disks enters the grinding chamber, where the particles lose their speed and pour through a discharge funnel into a collection container.

The output of the DG 175M disc grinder depends on the hardness of the material, the setting of the discharge slot, the initial grain size of the material and the required grain size of the product.
