Gypsum is a monoclinic mineral. The main component is calcium sulfate (CaSO4). Gypsum generally refers to two minerals, raw gypsum and anhydrite. Raw gypsum is also called dihydrate gypsum, anhydrite, or soft gypsum, usually in dense blocks Shape or fibrous, Mohs hardness is 2, anhydrite is anhydrous calcium sulfate, usually in the form of dense block or granular, white, off-white, glass luster, Mohs hardness is 3 to 3.5.

The first stage: the crushing of raw materials

The large gypsum material is crushed by the crusher to the feed fineness (15mm-50mm) that can enter the mill.

 

The second stage: milling

The broken small pieces of gypsum material are sent to the storage hopper through the elevator, and then sent to the grinding chamber of the mill for quantitative grinding through the feeder.

 

The third stage: classification

The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the host machine for re-grinding.

 

Fourth stage: collection of finished products

The powders conforming to the fineness are separated into and collected in the dust collector through the pipeline through the airflow, and the collected finished powders are sent to the finished product silo by the conveying device through the discharge port, and then uniformly packed with powder tankers or automatic baler.
