POP and gypsum board plant

The natural gypsum powder includes anhydrous gypsum and CaS04.2H2O, if you want to commercialize the gypsum powder, you should adopt the CaS04.2H2O, after removing part of water by heating, it will become CaS04.1/2 H20. CaS04.1/2 H20 is the final product which you can use it to produce gypsum board other gypsum product. After calcining, CaSO4.1/2H2O is widely used in paper faced gypsum board and gypsum block and painting gypsum powder and model.
Natural gypsum generally includes dehydrate gypsum and anhydrous gypsum. In order to get the valuable materials, generally, we get semi-hydrated gypsum through heating the dehydrate gypsum.

应用领域

This project can be dividing into six systems:Crushing , Grinding, Calcination, aging in silo , dust collection, and heating supply.

Brief introduction of technology is:

The first stage: Crushing

Crushing the gypsum rock into maximum 5mm size

Lifting the 5mm size gypsum particle into silo for storing, when the silo is full, the crusher will stop workingautomaticly when the Silo is fully , which can save energy.

The second stage: Milling

Milling the gypsum rock particle into 80-120mesh powder by our MTW Grinding mill. The powder is classified through a separator inside grinding mill. The qualified powder in required fineness shall be carried to the calciner, while the unqualified powder shall be returned to the grinding mill for further process.

The third stage: Grading

The powdered material is classified by the classifier, and the unqualified powder is classified by the classifier and returned to the host for re-milling.

The fourth stage: Collecting

Fine powder complies with the fineness with airflow go through the pipe into the dust collector for separation and collection. The finished powder collected by the delivery device is delivered to the finished product bin, and then packed uniformly with the powder tanker or automatic packing machine.
