the tabuk marble ultrafine project saudi arabia
in the tabuk region of northwestern saudi arabia near the red sea coast a sophisticated industrial project is producing ultrafine marble powder for high-value applications in the plastics and paint industries. this is the tabuk marble ultrafine project which features an advanced hgm series ultrafine grinding mill stone powder grinding mill with a capacity of 2.5 tons per hour. the raw material is premium white marble from the famous deposits of the tabuk region known for their exceptional brightness and purity.
the hgm ultrafine mill is a state-of-the-art machine that uses multiple grinding rollers and a high-speed centrifugal classifier to achieve extraordinary fineness. the marble is carefully selected for its whiteness and purity then crushed and fed into the mill where high-pressure grinding rollers create a powerful grinding action. the integrated turbine classifier spins at high speed separating particles by size with exceptional precision. the target fineness for this operation is an incredible 8 microns which is finer than the finest cement and produces a powder with a silky smooth texture.
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 smaller portion of the production is sold to the cosmetics industry for use in high-end face powders and other personal care products.

the project faced immense technical challenges in achieving the 8 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 to prevent iron contamination 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 8 micron specification. the 2.5 tons per hour output of this stone powder grinding mill may be modest but the value per ton is exceptionally high supplying critical raw materials to saudi arabias growing manufacturing sector and supporting the kingdoms vision 2030 goals of industrial diversification and localization of supply chains.
