vietnamese construction sector supported by new medium capacity grinding mill
a state of the art limestone grinding mill has commenced operations in an industrial park near hanoi vietnam specifically designed to serve the booming construction market this vertical roller mill configuration is engineered for high efficiency and low energy consumption handling a substantial throughput of 12 to 16 tons per hour the mill is calibrated to produce a fine powder with a particle size distribution of 90% passing 200 microns this specific grade is essential as a high quality filler material for the production of portland cement and as a fine aggregate supplement in specialized concrete mixes
unlike traditional ball mills this vertical roller mill utilizes a grinding table and conical rollers to crush and pulverize the limestone . the material is fed onto the rotating table and is crushed beneath the hydraulic pressurized rollers. an integrated air classifier immediately separates the fine particles, returning oversize material for further grinding. this closed circuit system ensures a highly uniform product which is vital for maintaining the strength and workability of concrete. the mills variable frequency drive allows the operator to adjust the rotational speed, fine tuning the energy consumption to match the desired output fineness which for this project is tightly controlled around 74 microns
the use of this domestically processed limestone powder reduces vietnams dependence on imported construction materials. the plant manager notes that the mills ability to produce a consistent 200 mesh powder with a 15 ton per hour capacity has stabilized their supply chain for high rise construction projects in hanoi. the powder acts as a microfiller in concrete, reducing the paste volume needed and enhancing the durability of the final structure. as vietnam continues its rapid urbanization this grinding mill stands as a critical piece of infrastructure turning local mineral resources into high value construction inputs
