About millstones, grindstones, grinding wheels and the like, without frameworks, for working stones, and parts thereof, of natural stone, of agglomerated natural or artificial abrasives, or of ceramics; natural or artificial abrasive powder or grain, on a base of textile, paper or other material

cpc code 3791 covers a diverse range of abrasive products used in various industrial and commercial applications. These products, which include millstones, grindstones, grinding wheels, and abrasive powders or grains, play a crucial role in shaping, polishing, and refining a wide array of materials. This industry is an integral part of the broader manufacturing and construction sectors, providing essential tools and materials for processes such as stone cutting, metal finishing, and surface preparation.

Production process

The production of the items covered under cpc code 3791 typically involves a combination of mechanical and chemical processes. Millstones, grindstones, and grinding wheels are often manufactured by bonding natural or artificial abrasive materials, such as silicon carbide or aluminum oxide, to a base material like stone, ceramic, or metal. The abrasive powder or grain is produced by crushing, grinding, and sieving raw materials to the desired particle size and composition.

Production inputs

The main inputs required for the production of cpc code 3791 items include natural stones (e.g., granite, sandstone, or limestone), synthetic abrasives (e.g., silicon carbide or aluminum oxide), and binders (e.g., resins or ceramics). Additionally, specialized machinery, such as grinding mills, presses, and kilns, are necessary for the manufacturing process. The availability and quality of these raw materials and equipment are crucial for the industry's productivity and the performance of its products.

Production outputs

The primary outputs of the cpc code 3791 industry are millstones, grindstones, grinding wheels, and abrasive powders or grains. These products are widely used in various industries, including 3792 Cutlery, 3812 Machinery for mining, quarrying and construction, 3822 Machinery for food, beverage and tobacco processing, and 3829 Other special-purpose machinery. The abrasive materials and tools produced under this code are essential for shaping, polishing, and refining a diverse range of materials, from stone and metal to glass and ceramics.
