About clays

cpc code 1540 covers the industry of clays, which are naturally occurring, fine-grained, earthy materials that are widely used in a variety of applications. Clays play a crucial role in various industries, including ceramics, construction, and manufacturing, making them an essential component of the broader economy. Their unique physical and chemical properties make them indispensable raw materials for a wide range of products.

Production process

The production of clays typically involves the extraction of the raw material from natural deposits, followed by processing and refining. This may include steps such as crushing, screening, washing, and drying to remove impurities and achieve the desired particle size and composition. Depending on the specific application, clays may undergo further processing, such as calcination or chemical treatment, to enhance their properties.

Production inputs

The main inputs required for the clay industry include the raw clay deposits, which are typically found in natural geological formations. Additionally, the industry relies on various machinery and equipment for the extraction, processing, and transportation of the clay materials. Energy sources, such as electricity or fuel, are also necessary for the various stages of production.

Production outputs

The primary outputs of the clay industry are the refined and processed clay materials, which are then used as inputs for a wide range of industries. These include the 2610 Ceramic Products, 2330 Cement and Concrete Products, and 3250 Medical and Dental Supplies and Equipment industries, among others. The specific applications of clays can vary greatly, from the production of bricks and tiles to the manufacture of advanced ceramic components and medical devices.
