Are you thinking of building a gypsum board plant and need to evaluate your gypsum supply? Are you an existing manufacturer who is considering a different supply of gypsum? Want to start using Raw material but do not know where to start?

At Gypsboard® laboratory we analyze any gypsum for many purposes.

1-Even small amounts of some impurities in gypsum can cause issues with processing equipment and future product performance in gypsum board or plasters. Unknown composition represents a liability risk.

We can test both natural rock and byproduct gypsum using chemical mineral analysis to determine the gypsum quality and what impurities are present.

2-The processes of evaporating water and grinding have high energy costs. An optimum efficiency can be achieved in product quality while minimizing costs of operation.  We can dry gypsum that has free water and can crush and grind gypsum to powder.  We can also measure grind ability and hardness.

3-Crystal size, shape and aspect ratio can contribute to materials handling behaviors and calcination efficiency.

 We can measure gypsum powders for particle size distribution using laser diffraction or sieve analysis and can analyze crystal properties using optical microscopy (OM).

4-Can your gypsum source be used to produce gypsum board or plaster? Using our lab scale calcination equipment and our ability to make lab gypsum board samples, we can evaluate what is possible. Acid insoluble residue, S content, chloride content and insoluble anhydrite content are often requested.
