The quang ninh gypsum powder plant vietnam from china
in the quang ninh province of northern vietnam known for its world-famous ha long bay a different kind of landscape is being shaped by industry. here the quang ninh gypsum powder plant project is utilizing a large stone powder grinding mill to process natural gypsum rock into a fine powder essential for the construction sector. the project employs a vertical roller mill specifically designed for gypsum with a high processing capacity of 20 tons per hour.
the gypsum is sourced from local mines in the region and is characterized by its high purity and white color. within the mill the gypsum is ground and simultaneously calcined using the hot gas generated by an external furnace. the target fineness for the finished product is 200 microns which corresponds to 80 mesh.
this powder is the primary ingredient for producing plaster of paris which is used in making decorative moldings ceiling tiles and for internal wall plastering in the booming construction markets of hanoi and haiphong. the project was initiated to meet the growing domestic demand for high-quality construction materials and to reduce vietnams dependence on imported gypsum from thailand and china.
the vertical roller mill was chosen for its energy efficiency and its ability to combine grinding and calcining in a single unit simplifying the process flow. a significant challenge was the high moisture content of the local gypsum which can reach up to 10 to 12 percent during the rainy season. the mills integrated drying system using exhaust gases from the furnace was designed with extra capacity to handle this peak moisture ensuring continuous and uninterrupted operation.
the 20 tons per hour output from this stone powder grinding mill now supplies dozens of small and medium-sized plaster workshops across the red river delta supporting local artisans and the modern construction industry alike.
