For over 60 years, FEECO International has built a reputation as the leader in rotary kiln design and manufacturing. Part of our success is owed to the FEECO Innovation Center, a state-of-the-art testing facility where our team of process experts conduct a variety of thermal tests to assist us in determining one's custom engineered kiln needs.

Nearly all cement plants have received permits from their local regulators to co-process these waste derived materials. The infrastructure built at the cement plants to handle these imports from Germany, and the experience of operating the cement kilns with these alternative materials, were accelerating factors in Poland's recent developments.

A by-product of the cement production process is a fine chalky powder waste known as cement kiln dust. River Cement disposed of the dust, which could contain hazardous constituents, in several on-site landfills. The "old" landfill, which was roughly 400 ft x 3,000 ft x 25-50 ft deep, was located in the southeast corner of the facility.

The cement kiln is a typical example of a sintering furnace. Kilns are used in the cement industry for calcining lime and are made in various forms. Rotary cement kilns as used in the cement industry take the form of a long cylinder supported on rollers. They vary …

Aug 30, 2012· Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.

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.
