the quang binh limestone project vietnam
in the quang binh province of central vietnam a region known for its stunning phong nha cave system and dramatic karst landscapes a project is processing local limestone into industrial minerals for the construction and manufacturing sectors. this is the quang binh limestone project which features a vertical roller mill stone powder grinding mill with a capacity of 22 tons per hour. the raw material is high-purity limestone from the famous mountains of quang binh where some of the most extensive limestone formations in vietnam are found.
the vertical roller mill was chosen for its energy efficiency and its ability to handle the high moisture content of the raw material which can be significant in the tropical climate of central vietnam. the mill uses hot gases from a coal-fired furnace to dry the limestone during grinding reducing the moisture to below 1 percent in a single operation. the target fineness is 125 microns approximately 115 mesh a versatile specification that serves multiple markets.
the primary application of this limestone powder is in the production of wall putty for the construction industry in central vietnam where a boom in residential and commercial construction has created strong demand for high-quality finishing materials. the fine powder is also supplied to animal feed manufacturers who use it as a calcium supplement and to local plastic pipe producers who use it as a functional filler. the 22 tons per hour capacity makes this one of the largest limestone grinding operations in central vietnam capable of supplying customers across a wide region.
the project faced significant logistical challenges in an area with developing transportation infrastructure and a challenging climate with frequent typhoons and heavy rainfall. the solution was to locate the plant adjacent to the national railway line allowing finished product to be transported efficiently by rail to customers throughout vietnam. covered material handling systems protect the product from moisture during the rainy season while backup power generation ensures continuous operation even during grid outages caused by storms. this stone powder grinding mill project in quang binh has brought modern industrial processing to one of vietnams historically important provinces creating employment and supporting regional economic development.
