Lime
Each lime kiln type and design is able to accommodate a given set of limestone characteristics. Testing to determine the suitability of a limestone for feed to a lime kiln is performed at 's Process Research & Test Center in Danville, Pennsylvania, USA using proprietary test procedures, referred to as a Limestone Evaluation (or LSE).

Solar treatment of cohesive particles in a directly irradiated rotary kiln
The first trials on solar calcination were made in 1980 by Flamant et al. in two different directly irradiated reactors, a fluidized bed and a rotary kiln (Flamant et al., 1980).In the fluidized bed reactor the particles were in a controlled atmosphere (closed reactor), whereas in the rotary kiln the particles were in contact with ambient air (open reactor).

SOLAR CALCINATION OF MINERALS
Of all the proposed concepts, the most used and studied are rotary kilns. After the first concept, proposed by Flamant, Meier et al. tested an open rotary kiln with a flow of 2.3 kg/h of 2–3 mm limestone particles. Calcination above 95% could be reached. In order to ensure a good particle mixing, high rotational speeds were required.
