The tamil nadu red mineral project india
in the southern indian state of tamil nadu near the temple city of madurai a unique industrial project is processing locally abundant red ochre and laterite stones into valuable pigments and construction materials. this is the tamil nadu red mineral project which features a versatile ball mill stone powder grinding mill with a capacity of 3 tons per hour. the raw materials are soft to medium-hard iron-rich stones that vary in color from deep red to yellowish-brown depending on their exact mineral composition.
the ball mill grinds these stones into a fine powder with a target fineness of 100 microns or approximately 150 mesh. the grinding process uses a combination of steel balls and ceramic media to avoid iron contamination which could alter the natural color of the pigments. the resulting powder has two primary applications. the highest quality material with the purest red color is sold to traditional artists and paint manufacturers who use it as a natural pigment in heritage restoration projects and in the production of traditional south Indian wall finishes.
the lower grade material with less intense color is sold to the construction industry as a pozzolanic additive for cement where its iron oxide content contributes to the strength and durability of concrete. the project faced the challenge of sorting and blending different raw material grades to achieve consistent color in the final pigment product. the solution was to implement a rigorous quality control system with careful stockpiling and blending before grinding.
the 3 tons per hour output from this stone powder grinding mill supports a niche but culturally significant industry preserving traditional building practices while also contributing to modern construction in the rapidly growing cities of tamil nadu.
