the chanthaburi marble powder project thailand
in the chanthaburi province of eastern thailand a region famous for its gemstones and tropical fruits a project is processing local marble into high-value industrial minerals. this is the chanthaburi marble powder project which features an advanced ultrafine grinding mill stone powder grinding mill with a capacity of 3.5 tons per hour. the raw material is white marble from the famous deposits of the chanthaburi mountain range where metamorphic processes have created some of the purest calcium carbonate in thailand.
the ultrafine grinding mill uses multiple grinding rollers and a high-speed centrifugal classifier to achieve an extraordinary fineness of 10 microns. at this particle size the marble powder is finer than cement and has a smooth creamy consistency. the grinding process uses wear-resistant ceramic components throughout to prevent iron contamination ensuring that the brilliant white color of the marble is preserved in the final powder which achieves a brightness of over 95 percent.
this ultrafine marble powder has several high-value applications in modern manufacturing. its primary use is as a functional filler in the production of masterbatch for the plastics industry where its fine particle size ensures excellent dispersion and a smooth surface finish in extruded plastic products. it is also used in high-end automotive paints and industrial coatings where it provides a brilliant white base and improves the durability and scratch resistance of the final finish. a portion of the production is supplied to the cosmetics industry for use in high-end face powders and other personal care products where the 10 micron particle size provides a silky smooth texture.
the project faced immense technical challenges in achieving the 10 micron fineness consistently while maintaining the brightness and purity of the final product. the solution was to line all product contact surfaces with wear-resistant ceramics and to use an advanced air classification system with a precision turbine that separates particles by size with exceptional accuracy. a laser particle size analyzer monitors the product continuously automatically adjusting the classifier speed to maintain the precise 10 micron specification. the 3.5 tons per hour output of this stone powder grinding mill in chanthaburi supplies critical raw materials to thailands growing manufacturing sector demonstrating how traditional mineral wealth combined with advanced processing technology can create products that compete in the most demanding global markets.
