The present invention relates to a mixer, the method of mixing and method of manufacture of gypsum boards that are used in the production process of gypsum slabs by
Gypsum rock is mined or quarried, crushed and ground into a fine powder. In a process called calcining, the powder is heating to approximately 350 degrees F, driving off three fourths of the chemically coined water. The calcined gypsum, or hemihydrate, becomes the base for gypsum plaster, gypsum board and other gypsum products.
Making Gypsum Board To produce gypsum board, calcined gypsum is mixed with water and additives to form a slurry which is fed between continuous layers of paper on a board machine. As the board moves down a conveyer line, the calcium sulfate recrystallizes or rehydrates, reverting to its original rock state.
Sets in 25-35 minutes after machine mixing (NOTE — It can only be mixed by a batch process, not by a continuous process mixer or by hand) Requires 32 parts water by weight per 100 parts plaster. NOTE — For best storage results, keep indoors in a dry, stable environment, away from drafts.
The Pin Mixer works as a primary feed conditioner to the gypsum pelletizing process, mixing the powdered gypsum with a binder solution. The rotational motion of the pins imparts a spinning action to the gypsum mixture, eliminating air and reducing water volume between particles.
Gypsum mining process products are most popular in Africa, Domestic Market, and Southeast Asia. You can ensure product safety by selecting from certified suppliers, including 173 with ISO9001, 107 with Other, and 23 with OHSAS18001 certifiion.
2017-10-10 · The crushed raw gypsum is heated and calcined by adding heat through the bottom, the walls and the flue passes. The constant mixing process within the kettle helps homogenize the material to be calcined and leads to a high quality product through an
Gypsum board is the generic name for a family of panel products that consist of a noncoustible core, composed primarily of gypsum, and a paper surfacing on the face, back and long edges. Gypsum board is often called drywall, wallboard, or plasterboard.It differs from other panel-type building products, such as plywood, hardboard, and fiberboard, because of its noncoustible core and paper
When designing a gypsum processing system, most attention focuses on larger equipment such as disc pelletizers or rotary dryers.However, the importance of a pin mixer for gypsum processing should not be overlooked. Pin mixers offer numerous benefits such as solids mixing, densifiion, and granulation.
2010-8-13 · Generic Gypsum . Product Selection and Description . Approximately 2.25 % of the gypsum board produced is lost as waste during the manufacturing process. Installation Gypsum board may be attached to wood framing, coldformed steel framing, or exist- ing surfaces using nails, staples, screws, and adhesives appropriate for the appliion.
