Cutting discs

Grinding consists of two stages: rough grinding and fine grinding. Rough grinding is taken care of by two overlapping conical tools; these break down the raw product and send it to the fine grinding unit.
In the fine grinding stage the Colombini cutting discs, constructed in sintered hard metal, grind the product progressively by passing it through three crowns of teeth (rough, intermediate and fine grinding) progressively grinding it into powder. At the end of this stage the product has reached the required granulometry.
Rough grinding units and cutting discs are designed according to the type of product to be ground, to optimise the final results.
