System for compacting ceramic powders for forming slabs using a belt

摘要

A system (1) for compacting ceramic powders for forming slabs using a belt comprising:
- a conveyor belt (40) on which a continuous strip (S) of powdered ceramic material is created;
- a first bottom compacting belt (20) arranged in contact with the conveyor belt (40) and below it;
- a second top compacting belt (30) cooperating with said first belt (20) and having a first receiving portion (30a) having an inclination (²) with respect to the direction in which the powders (S) advance, and a second expansion portion (30b), where the length (A) of the portion of powder (S) involved at the instant of compacting is between 2 and 28 times the thickness of the powders (S).
