Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower.

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

Achieve world-class production capacity in your kiln. In this section we focus on dry-process kilns, as they represent the majority of kilns now in use. The refractory requirements of wet- and semi-dry process kilns are essentially similar after the inlet stage. Today's dry-process kilns are shorter, without loss of production capacity.

Industry Status Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden.

Cement Industry Overview

This spike in labor efficiency is the result of industry efforts to increase efficiency by automating production and closing small kilns. The average kiln in use today is capable of producing 89.9 percent more clinker than an average kiln produced 20 years ago: 678,000 metric tons in 2012 compared with 357,000 metric tons in 1992.
