Machines; for crushing or grinding earth, stone, ores or other mineral substances

HS v2017 Code: 847420

About machines; for crushing or grinding earth, stone, ores or other mineral substances

hs code 847420 covers a critical segment of the mining and mineral processing industry. These machines are essential for the initial stages of extracting and refining raw materials, such as 250100 Ores; iron and 251710 Stones; limestone, gypsum, chalk and slate. The efficient operation of these crushing and grinding machines directly impacts the productivity and cost-effectiveness of a wide range of downstream industries, making this code a vital component of the broader global economy.

Production process

Machines classified under hs code 847420 utilize a variety of mechanical processes to reduce the size of solid materials. Common techniques include impact crushing, where materials are struck by a high-speed rotor or hammer, as well as compression crushing, where materials are squeezed between two surfaces. Grinding machines employ rotating drums or discs to grind materials into finer particles through attrition and shear forces.

Production inputs

The primary inputs for the production of hs code 847420 machines include various metal alloys, such as steel and cast iron, for the structural components, as well as electric motors, gearboxes, and other mechanical parts. Specialized wear-resistant materials, like tungsten carbide, may be used for the crushing and grinding surfaces to ensure durability and longevity. Additionally, these machines require a range of supporting components, including hydraulic systems, control electronics, and safety features.

Production outputs

Machines classified under hs code 847420 are used to process a wide variety of solid materials, including 250100 Ores; iron, 251710 Stones; limestone, gypsum, chalk and slate, and other mineral resources. The crushed and ground materials produced by these machines are then typically fed into further processing steps, such as 847450 Machines; for sorting, screening, separating, washing, crushing, grinding, mixing or kneading earth, stone, ores or other mineral substances, in solid form, 842123 Machinery; for filtering or purifying gases, or 842129 Machinery; for filtering or purifying liquids, depending on the specific application and industry.
