widely used gypsum powder productin line

Specifications

The main composition of gypsum is hydrate gypsum(CaSO₄.2H₂O). however, the gypsum powder used in practical production(such as the gypsum powder for gypsum board, for mould, for plastering)is to dry and dewater the dehydrate gypsum which of certain fineness, reduce the content of crystallization water in it, so the standard of crystallization of gypsum powder can qualify all kinds of gypsum powder, because it can change into plaster of pairs. Plaster of pairs can re-integrated with water when it is applied into production, and it can be processed into new type building materials with a high intensity, such as gypsum board, gypsum block, etc.

Existing gypsum powder drying technologies are frying boiler and rotary kiln plant. It means that put the gypsum powder into the frying boiler and coil pipe, and before the gypsum powder was put, the heat produced by the burning of the medium in kiln furnace was send into the frying boiler and rotary kiln plant by fan. In this way, the quality of gypsum powder is difficult to guarantee, because the content of crystallization water is uneven.

New-type gypsum frying boiler- ebullience calciner    

First grind and second bake. The largest advantage of this technique, compared with that of “first grind and second bake”, is energy consumption reduction. Large plaster stone shall be ground into powders with diameter less than 0.2mm, which increases the specific surface when calcining, enlarges the contact area with heat medium, improves calcination heat exchange efficiency and lowers energy consumption greatly. This equipment has small bulk, large production capacity, and simple structure and is hard to destroy.

Note: in addition to the above mentioned equipment, we also provide the design for the entire production line and auxiliary equipment election. We will send technical engineer to the buyer’s site for installation and debugging machine until the quality gypsum is produced.
