Gypsum is a naturally occurring mineral that serves many purposes, with the United States producing the largest crude gypsum in the world. Cover walls, ceilings, plasters, fertilizers, cosmetics and some foods: gypsum’s vast applications granted it the recognition of “wonder mineral”. Gypsum making equipment helps in making gypsum powder or board for industrial use.

Getting fine particles with gypsum making equipment

Gypsum crystals go through crushing to achieve a desired degree of fineness. To achieve this, you can use a reclaim crusher, which depending on the design can also give room for recycling. Another key process in making gypsum is heating. This helps achieving the desired moisture content of the gypsym. To dry the product, feed the fine raw materials into the hot gas flow of the calciner. It is important to control and keep the temperature in check when operating gypsum making equipment. Heating above 152 ⁰C (305.6 ⁰F) may cause total water loss and dead-burnt gypsum.

Gypsum boards, a common end-product of gypsum

The construction industry commonly uses gypsum because of its resistance to heat. The most common end-product is the gypsum board (drywall) or plaster board to produce false ceilings.

To make gypsum board, mix the calcined gypsum with water and additives to form slurry. Then feed the mixture between stacked papers on a gypsum board making machine. The mixture recrystallizes and bonds with the paper. It must dry to remove water before adding finishing touches such as coating and painting. Aesthetically, false ceilings are more appealing, and it’s also possible to install lights on them. This type of ceiling doesn’t conduct heat and prevents fire. They are good sound insulators and durable depending on how they’re managed.

Post-industrial activities: environmental impact of making gypsum

Like every other mineral, gypsum processing releases chemicals. But by-products like sulphur are mostly reintroduced into the process, which makes tit more sustainable. It also reduces the effect of gypsum mining activities and waste disposal on ground water and on the atmosphere. Another alternative is to use synthetic gypsum produced from burning fuels for power generation. It is an easier substitute because instead of releasing it as a by-product, it is reused as it has the same chemical properties as the natural ones. Post-industrial recycling activities help produce new gypsum products while retaining its quality.

Gypsum, a cost-effective alternative for cement sand

Asides from making plaster of Paris, you can build concrete blocks and partitions with a gypsum making machine. When plastering, gypsum reduces construction time and cost compared to using typical cement sand. It is lightweight and, most importantly, reduces greenhouse gas emissions. To produce high-quality gypsum boards and build consumer confidence, you have to meet the standard codes and regulations bodies like ASTM in order to facilitate trade. For example, ASTM C1264-19 specification covers sampling inspection, rejection, certification, packaging, marking, shipping, handling, and storage of gypsum panel products.
