Gypsum recycling plants made by ReTec

The gypsum recycling mill developed by ReTec has the purpose to prepare gypsum e.g. from old plasterboards for new gypsum production. The mill ensures a very high degree of separation between paper and gypsum; the two fractions: One paper fraction that largely is free of gypsum and a fraction consisting of gypsum that, depending on the input material, consists of mainly pure gypsum.

Gypsum

Gypsum is a slow-release source of sulphur and calcium which play a key role in improving soil structure, aeration and water retention. So you can grow better, healthier crops.When Gypsum dissolves, it releases equal proportions of calcium and sulphate. Calcium sulphate improves the structure and consistency in soil and most other growing media allowing better water penetration and retention ...

Plaster Powder Plant

By heating of gypsum found in nature (CaSO4+2H2O) to 150 to 160 C, 1,5 mol water evaporates of 2 moles in the chemical structure and it is changed as CaSO4+1/2H2O called calcination process. Gypsum loses mass of around 15% during calcination, i.e. if 1000 kg of gypsum plaster is calcined, approximately 850 kg plaster remains, and 150 kg of water vapor is emitted from the chimney.
