The design of the screw is based on the theory of the inclined plane. The screw conveyor began to evolve in the late 1800s and was used as a means of increasing food and grain production to meet the needs of the rapidly growing American population. The first feed mills used screw conveyors throughout the process.

Clinkering is the primary step in the cement manufacturing process. The function of the kiln in the cement industry is to first convert limestone into lime, then react it with silica, aluminum oxide, and ferric oxide to form clinker compounds: C3 S, C 2 S, C 3 A, and C 4AF. The kiln is the heart of this production process.
