the da nang limestone grinding project vietnam
in the coastal city of da nang in central vietnam a strategic industrial project is processing local limestone into a versatile powder that serves multiple industries across the region. this is the da nang limestone grinding project which features an advanced mtw european trapezium mill stone powder grinding mill with a capacity of 16 tons per hour. the raw material is high-purity limestone sourced from quarries in the nearby marble mountains a range of limestone hills that have provided stone for centuries to local artisans and industries.
the mtw mill was selected for its energy efficiency and its ability to produce a consistent product with minimal maintenance requirements. the limestone is crushed and fed into the mill where grinding rollers press against a stationary grinding ring pulverizing the stone into a fine powder. the integrated air classifier ensures that only particles meeting the specification escape the grinding chamber while oversize material is returned for further processing. the target fineness for this operation is 125 microns approximately 115 mesh a versatile specification that serves multiple markets.
the applications for this limestone powder are diverse and essential to the regional economy. the primary market is the construction industry where the powder is used as an additive in the production of high-quality wall putty for the booming real estate market in da nang and the neighboring city of hoi an a unesco world heritage site. the fine powder is also supplied to local animal feed manufacturers who use it as a calcium supplement for poultry and livestock and to plastic pipe manufacturers who use it as a functional filler in polyvinyl chloride products.
the project faced the challenge of operating in a region prone to typhoons and heavy monsoon rains which can disrupt transportation and power supplies. the solution was to design the plant with elevated structures and flood protection measures and to install backup power generation capable of running the critical systems during grid outages. covered conveyor systems protect the raw material from moisture during the rainy season ensuring consistent operation regardless of weather conditions. the 16 tons per hour output of this stone powder grinding mill has positioned da nang as a key supplier of industrial minerals to the entire central vietnam region supporting construction agriculture and manufacturing with a consistent high-quality product.
