In the north-central coastal province of nghe an vietnam a modern industrial project is harnessing local limestone resources to serve the growing demand for high-quality construction materials. this is the nghe an limestone powder project which features an advanced vertical roller mill stone powder grinding mill with a capacity of 18 tons per hour. the vertical roller mill was selected for its energy efficiency and its ability to dry and grind materials in a single operation an important consideration given the tropical climate of central vietnam. the raw limestone is quarried locally and contains relatively high moisture requiring an efficient drying system integrated into the mill.
The grinding process produces a fine powder with a target fineness of 125 microns or approximately 115 mesh. this versatile product serves several growing markets in the region. its primary application is as a raw material for producing high-grade wall putty used in the finishing of interior and exterior walls in the rapidly expanding residential and commercial construction sectors of vinh city and surrounding areas. the powder is also sold to animal feed manufacturers who use it as a calcium supplement and to local brick producers who mix it with clay to produce high-quality calcium silicate bricks.
The project faced significant competition from smaller inefficient mills that have operated in the region for decades. the advantage of this new facility is its consistent product quality and its ability to produce at a scale that serves large industrial customers. the 18 tons per hour capacity allows the plant to operate on a continuous basis supplying bulk tanker trucks that transport the powder directly to customer silos reducing packaging waste and transportation costs.
This stone powder grinding mill project in nghe an represents a significant step forward in the modernization of vietnams mineral processing industry bringing advanced technology to one of the countrys historically important provinces.
