Machines; for mixing mineral substances with bitumen

HS v2022 Code: 847432

About machines; for mixing mineral substances with bitumen

HS code 847432 covers machines used for mixing mineral substances, such as sand, gravel, or crushed stone, with bitumen. This industry plays a crucial role in the construction and infrastructure sectors, as the resulting bituminous mixtures are essential for the production of asphalt and other paving materials. These machines are widely used in road construction, maintenance, and repair projects, contributing to the development and upkeep of transportation networks worldwide.

Production process

The production of machines for mixing mineral substances with bitumen typically involves several key steps. First, the machine's frame and structural components are fabricated using metal alloys or other durable materials. Next, the mixing mechanism, which may include paddles, augers, or other agitating devices, is installed. The machine is then equipped with a heating system to maintain the bitumen at the appropriate temperature for mixing. Finally, the machine is outfitted with controls, sensors, and other features to ensure precise and efficient operation during the mixing process.

Production inputs

The main inputs required for the production of HS code 847432 machines include metal alloys for the frame and structural components, electric or hydraulic motors to power the mixing mechanism, and various electronic and mechanical components for the control systems. Additionally, the machines may require specialized materials for the mixing mechanism, such as heat-resistant and corrosion-resistant alloys. The production of these machines also relies on skilled labor, engineering expertise, and access to advanced manufacturing technologies.

Production outputs

The primary output of HS code 847432 machines is the production of bituminous mixtures, which are then used in the construction and maintenance of roads, highways, and other paving projects. These bituminous mixtures may be further processed or combined with other materials to create asphalt or other paving products. The output of these machines is often consumed by industries classified under 460110 Asphalt and bituminous mixtures, 230690 Other residues of the chemical or allied industries, and 681011 Building blocks and bricks, of cement, concrete or artificial stone, among others.
