Philippine customers purchased a set of limestone calcining rotary kiln from our company, and the equipment is currently running well. The crushed and screened limestone is sent to the lime kiln. In the rotary kiln, the limestone keeps rolling with the rotation of the kiln body and is evenly contacted with the hot gas, so as to achieve relatively complete calcination and decompose to produce quicklime and carbon dioxide. It is suitable for enterprises that produce lime on a large scale, with uniform calcination and stable product quality.
