<p>An apparatus for recovering raw gypsum from plasterboard or from other similar gypsum-based materials, comprising, in line,
- a hopper (11) for receiving plasterboard panels or panel portions and for a first reduction of the panels into first fragments,
- a first screen (15) for separating the first plasterboard fragments from any objects not made of plasterboard
- a drying oven (18)
- first means (19) for grinding
- a second screen (21), designed to separate the gypsum powder with an optimum particle size
- second means (24) for grinding
- a third screen (27), designed to separate the gypsum powder of optimum particle size
- means (31) for collecting and sending fragments that exit from the second screen (21) and the third screen (27) to
- a brushing assembly (30),
- a pneumatic assembly for aspirating, filtering and sending the gypsum of optimum particle size toward collection silos (32).</p> |
