The Foundation Optimization Solution of Lime Rotary Kiln

The common feature of early kilns was an egg-cup shaped burning chamber, with an air inlet at the base (the 'eye'), constructed of brick. Limestone was crushed (often by hand) to fairly uniform 20-60 mm (1 to 2.5 inch) lumps - fine stone was rejected. Successive dome-shaped layers of limestone and wood[8]or coal were built up in the kiln on grate bars across the eye. When loading was complete, the kiln was kindled at the bottom, and the fire gradually spread upwards through the charge. When burnt through, the lime was cooled and raked out through the base. Fine ash dropped out and was rejected with the 'riddlings'. Today we will introduce the lime kiln foundation optimization solution.

After careful discussion and examination, they get examine comment:

1. Agree the solution that use big diameter concrete column for rotary kiln main shell and for raw material silo and clinker silo use vertical concrete tubular pile solution.

2. Advise tubular pile for rotary kiln change to AB close type, effective length should be controlled in 30 meters.

3. Under precondition of satisfying rotary kiln design request, use tubular pile and square pile in priority. If it also can not satisfy request, assist to use filling pile column.

Attention that before using it, it should firstly optimize length and roughness of tubular pile to avoid problem of rotary kiln.

Lime rotary kiln features in simple structure, convenient and reliable control of the production process, less wearing parts, high rates of operation, its not only used to calcine high-grade cement in cement plant, but also widely used in metallurgical, chemical, construction and other industries. The rotary kiln produced by our plant has strong structure, stable operation, high-quality products from the kiln and so on advantages, we can also offer advanced efficient shaft preheater, five grade cyclone preheater.

At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of active lime line, pneumatic conveying eductor and free service for assembling various kinds of production line.
