Disc grinders VIBROTECHNIK

Disc grinders are designed for comminution of samples of bulk materials to a fine-grained state.

In disc grinders, comminution occurs by means of abrasion simultaneous compressive and shear strain of material particles between fixed and moving discs.

The grain size of the comminuted product is regulated by the gaps between the discs (openings) and the physical properties of the material.

The Disc grinder DG *5 is designed for comminution of small samples weighing up to 1.0 kg for analytical studies with strict requirements relating to sample purity: the sample is not contaminated by working parts of the grinder.

The Disc grinder DG **5Ðœ is a tabletop model of the DG **5. In addition to the reduced overall dimensions of the grinder, the method for adjusting the gap between the discs has been changed. This makes it possible to perform the adjustment while the electric motor is operating.

The Disc grinder DG **0 is a more powerful model of the laboratory-class equipment. It can be used for comminution of small samples weighing up to 3 kg, as well as for continuous comminution, by outfitting it with 1.8L or *0L receiving containers, as well as Feeders PG 1 or PG 2.

The Disc grinder DG **0 is high-power equipment designed for busy laboratories or small production facilities.

Advantages of VIBROTECHNIK Disc grinders:

• Use of discs with two types of working surface: wedge-shaped (for preliminary comminution) and flat (for regrinding);
• Positioning of discs strictly parallel to one another by adjusting the position of the fixed disc;
• Discs are made of wear-resistant materials: carborundum, high-strength iron or manganese steel;
• Increased disc service life (DG **5Ðœ, DG **0 and DG **0) due to:
  • Ability to rotate the discs **0 degrees;
  • Interchangeable moving and fixed discs;
  • Reversible operation.
• Safe operation of the grinders is ensured by:
  • Equipping the grinders with control panels;
  • Limit microswitches that prevent grinders from being started with the covers or grinding chambers open.
• Openings for monitoring the gap between the discs are provided in DG **5Ðœ, DG **0 and DG **0 stationary chambers.

Applications: ferroalloys, ore, granite, marble, limestone, coal, coke, slag, diatomaceous earth, silica gel, automotive catalyst, glass, salt.

Industries: mining, metallurgy, construction, chemical.
 

* The maximum allowable size of the initial material depends on its physical properties.

**If discs with tungsten carbide inserts are used.
