the quang ngai feldspar grinding project vietnam
in the quang ngai province of central vietnam a region known for its beautiful beaches and historical significance a sophisticated industrial project is processing local feldspar for the high-end ceramics industry. this is the quang ngai feldspar grinding project which features an advanced wet grinding ball mill system with a capacity of 6 tons per hour. the raw material is sodium feldspar sourced from nearby mines in the mountainous areas of the province where pegmatite deposits contain high-quality feldspar with low iron content.
feldspar is a critical raw material for the ceramics industry where it acts as a flux that lowers the melting temperature of the ceramic body and promotes the formation of a glassy phase that gives strength and translucency to the finished product. the wet grinding process was chosen for this application because it produces a more uniform particle size distribution and eliminates dust issues common in dry grinding operations. the feldspar is ground with water in the ball mill to produce a slurry with a target particle size of 45 microns approximately 325 mesh.
this fine feldspar slurry is supplied directly in liquid form to ceramic tile and sanitaryware factories in the nearby dungs quat economic zone. using the material as a slurry eliminates the need for drying and repulping at the customer site saving significant energy and reducing production costs for both the grinding plant and its customers. the 45 micron finesse ensures that the feldspar melts uniformly during the ceramic firing process creating a smooth homogenous body with excellent mechanical properties and a pristine white color.
the project faced the technical challenge of producing a consistent slurry with stable solids content and rheological properties. the solution was to install an online particle size analyzer and a density control system that automatically adjusts the water addition and grinding parameters to maintain the target specifications. the slurry is stored in continuously agitated tanks to prevent settling and pumped directly to customer facilities through a dedicated pipeline network. the 6 tons per hour capacity of this stone powder grinding mill has made quang ngai a strategic supplier to the vietnamese ceramics industry reducing dependence on imported feldspar from china and india and supporting the growth of domestic manufacturing.
