Vertical Lime Kiln

energy saving vertical lime kiln

What is a vertical lime kiln? Vertical lime kiln, also called shaft lime kiln, is a type of shaft kiln specially designed for lime calcining. Compared with rotary lime kiln, it has low construction cost, but there are many shortcomings, such as low utilization coefficient (<50%), high energy consumption ( >160kg of coal is consumed per ton of lime to produce), serious environmental pollution, high labor intensity, unstable calcination quality, etc.

AGICO Cement, as an experienced cement equipment supplier, is professional in manufacturing rotary kilns and vertical shaft kilns. TTHN vertical lime kiln is a new type of calcining kiln developed by AGICO that merges high efficiency, high yield, and high automation into a single. It overcomes the disadvantages of traditional shaft kilns, deeply favored by customers for significant energy saving, environmental protection, high automation, high finished product quality, low construction costs, and short construction periods.
