Dolomite ramming mix

HS v2017 Code: 251830

About dolomite ramming mix

HS code 251830 covers dolomite ramming mix, a specialized material used in various industrial processes. Dolomite is a naturally occurring mineral composed of calcium and magnesium carbonates, and the ramming mix is a prepared form of this material. This industry plays a crucial role in supporting a wide range of manufacturing sectors, from steel production to construction, making it an integral part of the broader economy.

Production process

The production of dolomite ramming mix typically involves mining and processing the raw dolomite material. The dolomite is extracted from quarries or mines, then crushed, graded, and blended with other additives to create the desired mix. The final product is then compacted and shaped into the appropriate form for its intended use.

Production inputs

The main inputs for the dolomite ramming mix industry include the raw dolomite mineral, as well as any additional binders, fillers, or other additives required to achieve the desired properties of the final product. Specialized equipment, such as crushers, grinders, and compaction machinery, is also essential for the production process.

Production outputs

Dolomite ramming mix is primarily used as a refractory material in various industrial applications, such as 720110 Steel production, 681011 Construction, and 840410 Boiler manufacturing. The output of this industry is consumed by these and other related industries that require a durable, heat-resistant material for their production processes.
