the ha'il industrial minerals project saudi arabia
in the ha'il region of northern saudi arabia a project is processing local basalt and gabbro into industrial minerals for the construction and manufacturing sectors. this is the ha'il industrial minerals project which features a durable high-pressure grinding mill stone powder grinding mill with a capacity of 6 tons per hour. the raw material consists of dark volcanic rocks from the harat haybar volcanic field where extensive lava flows have created vast deposits of high-quality basalt and related rocks.
basalt is one of the hardest and most abrasive materials to grind but its unique properties make it valuable for specialized applications. the high-pressure grinding mill uses spring pressure to exert tremendous force on the grinding rollers allowing them to crush this difficult material efficiently. the target fineness for this operation is 75 microns or 200 mesh a specification that balances reactivity with handling convenience for industrial applications.
the applications for this basalt powder are specialized and high-value. the primary market is the oil and gas industry where the powder is used as a weighting agent in drilling fluids for exploration wells in the northern region of saudi arabia. the high density of basalt makes it effective for controlling formation pressures during drilling while its chemical inertness ensures it does not interfere with the drilling fluid properties. a smaller portion of the production is sold to the construction industry as a high-performance additive for specialized concretes requiring exceptional durability and abrasion resistance.
the project faced the challenge of producing a consistent product from a raw material that can vary in composition depending on the specific lava flow from which it was quarried. the solution was to implement a careful quarry management plan with selective mining of specific rock types and a blending program that mixes material from different sources to achieve a consistent feed chemistry. a laboratory equipped with x-ray fluorescence analyzers tests every batch of raw material and finished product ensuring that the drilling fluid specifications are consistently met. the 6 tons per hour output of this stone powder grinding mill supports the ongoing development of saudi arabias northern oil and gas fields.
