During this process, these materials partially fuse to form nodular shaped clinker by breaking of chemical bonds of the raw materials and recombined into new compounds. The clinker is cooled and ground to a fine powder with the addition of about 3 to 5% of gypsum. By this process, the product formed is Portland cement.

The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4% and in case of Quick setting cement it can be reduced up to 2.5%. Role of Gypsum in Cement The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water.
The pulverized Gypsum was calcined in a vessel of some type, likely ceramic. The resulting product, eventually many hundred of years later, named Plaster of Paris, provided this early man with a medium for making cast objects. In the grinding stage the fineness most generally is turned out at 90-93% minus 100 mesh with a 325 mesh range of 30 to ...
In this process, the natural gypsum is first fed to a Pfeiffer MPS mill where the material is dried and simultaneously ground to the required fineness for plaster. Subsequently, the ground and dried gyp- sum is delivered to the gypsum kettle ( Fig. 3). The kettle filled with finely ground gypsum is heated from outside.
The ground gypsum exits the mill in a gas stream and is collected in a product cyclone. Ore is sometimes dried in the roller mill by heating the gas stream, so that drying and grinding are accomplished simultaneously and no rotary dryer is needed. The finely ground gypsum ore is known as landplaster, which may be used as a soil conditioner.

Building plaster powder production project (raw material: natural gypsum ore, flue gas desulfurization gypsum, ardealite) is divided into 4 steps: crushing, grinding, calcining and loading. Detailed process: after being exploited, raw material will be taken to crusher to be crushed, then elevator will take material to stock bin, vibrating ...
Grinding, for example in a ball, rod, or hammer mill, is necessary if the gypsum is to be used for high quality plasterwork or for moulding, medical, or industrial applications. Unlike with other cements, such as lime and Ordinary Portland Cement, special mills for mineral grinding may not be required and the relatively soft gypsum could be ...

wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11.16-1. In this process gypsum is crushed, dried, ground, and calcined.
One suggested method for manufacturing walling blocks is based on phosphorgypsum processing, which permits excluding the grinding process of the binder (Fig. 25.17).It is an energy-efficient method for producing items directly from phosphorgypsum, providing the implementation of two chemical processes: dehydration of dihydrate and hydration of …

Increasing the gypsum content above 2% resulted in a decrease in strength. Increasing the gypsum content increases the C/S ratio of the C-S-H formed, which corresponds to a decrease in the intrinsic strength of the C-S-H gel. This occurs due to excessive gypsum, which reacts with the C-S-H gel formed and changes its structure.
