PREPARING CLAY; PRODUCING MIXTURES CONTAINING CLAY OR CEMENTITIOUS MATERIAL, e.g. PLASTER (preparing material for foundry moulds B22C5/00)

Introduced: September 1968

Description

B28C covers machinery and processes for clay preparation and the production of clay-based or cementitious mixtures, including plaster formulations. This classification encompasses mixing, blending, and conditioning equipment used to process raw clay, combine clay with other materials, or prepare cementitious compositions before molding or casting. Technologies in this scope typically serve applications in construction materials, ceramics, and refractory manufacturing where consistent mixture quality is essential. Related but distinct processes such as final shaping of clay products or cement hydration during setting fall under adjacent classifications.
